This study introduces a novel sandwich-structured composite incorporating varying contents of zirconium diboride (ZrB 2 ), with polybenzimidazole (PBI) as the resin matrix and quartz fiber felt (QF) as the reinforcement. The ablative performance of the composites was assessed under high-energy continuous wave laser conditions, featuring a laser power density of 30 MW m -2 , and the laser ablation morphology and ablation mechanism of the ZrB 2 /PBI/QF composites were investigated. Further analysis examined the effects of ZrB 2 ceramic content on the density, thermal stability, mechanical properties, ablation characteristics, and rear surface temperature of the composites. Upon laser ablation, ZrB 2 oxidizes, forming a protective white ZrO 2 layer. At a 60% ZrB 2 content, the rear surface temperature of the composites reached 1031 °C after 42 s, resulting in a low linear ablation rate (0.12 mm s -1 ). The gases and residual carbon produced by the pyrolysis of PBI resin, the melting of QF, and the release of SiO 2 gas contribute to the formation of a SiO 2 protective layer. Building on this foundation, the incorporation of ZrB 2 further enhances energy dissipation and facilitates the development of a ZrO 2 -SiO 2 protective layer with increased reflectivity. This layer, along with another oxidation product, B 2 O 3 gas, serves to isolate oxygen and mitigate erosion. The findings suggest significant potential for developing advanced materials for high-energy continuous wave laser protection.

Lightweight and high-strength insulation materials have important application prospects in the aerospace, metallurgical, and nuclear industries. In this study, a highly porous silica fiber reinforced phenolic resin matrix composite was prepared by vacuum impregnation and atmospheric drying using quartz fiber needled felt as reinforcement and anhydrous ethanol as a pore-making agent. The effects of curing agent content on the structure, composition, density, and thermal conductivity of the composite were studied. The mechanical properties of the composite in the xy direction and z direction were analyzed. The results showed that this process can also produce porous phenolic resin (PR) with a density as low as 0.291 g/cm3, where spherical phenolic resin particles are interconnected to form a porous network structure with a particle size of about 5.43 μm. The fiber-reinforced porous PR had low density (0.372~0.397 g/cm3) and low thermal conductivity (0.085~0.095 W/m·K). The spherical phenolic resin particles inside the composite were well combined with the fiber at the interface and uniformly distributed in the fiber lap network. The composite possessed enhanced mechanical properties with compressive strength of 3.5–5.1 MPa in the xy direction and appeared as gradual compaction rather than destruction as the strain reached 30% in the z direction. This research provides a lightweight and high-strength insulation material with a simple preparation process and excellent performance.

The robust human–machine interaction systems of the aerospace industry necessitate the development of thermal resistant wave-transparent composites, with a pivotal focus on organic resin matrix. However, enhancing the heat resistance of such materials while preserving other critical attributes has been a formidable challenge. In this study, a novel designed strategy of a dual-curing functional phosphorus-based phthalonitrile monomer (P-ALK-PN) has been proposed. The optimized curing temperatures for intra- or intermolecular Diels-Alder reactions of alkynyl groups and polyaddition reaction of cyano groups resulted in a homogeneous and highly crosslinked N-enriched phthalonitrile system. After curing at 450 °C, the resin, namely P-ALK-PN-450 °C, demonstrated exceptional thermal stability ( T 5% = 644 °C), thermo-oxidative stability ( T 5% = 554 °C), and char yield at 800 °C (90.7 % in N 2 and 67.5 % in air). Their quartz fiber reinforced composites (P-ALK-PN/QFs) were subsequently fabricated by the hot-pressing process. Upon post-curing at 420 °C, P-ALK-PN-420 °C/QF displayed elevated glass transition temperature (550 °C), flexural strength (319 MPa), and relatively low dielectric properties with a dielectric constant (D k ) of approximately 4.2 and a dissipation factor (D f ) less than 0.02 across a wide temperature ranging from 25 °C to 600 °C. Especially, it exhibited excellent flame retardancy (only a 6.7 % weight loss at ambient temperatures exceeding 1300 °C for 200 s) as well, stemming from release of eco-friendly inert gases (NH 3 ) and formation of a graphitized protective layer during pyrolysis. These promising results highlight the potential applications of P-ALK-PN resins in aerospace and high-performance engineering fields.

Island-shaped Ag nanoparticles are prepared under the support platform of quartz fabric by a simple chemical deposition method. The prepared flexible SERS substrate in this study demonstrates highly sensitive, excellent signal reproducibility and stability. The enhancement ability can be adjusted by varying concentration of Ag + during synthesizing process, which would lead to the variation of size and gaps of Ag nanoparticles , thus affecting the LSPR effect. Moreover, the prepared SERS substrate shows great practical potential in rapid detection of contaminated fruit with different sampling method.

Chopped quartz fiber-reinforced fused silica (SiO 2 f /SiO 2 ) composites were fabricated by stereolithography . The fiber orientation characteristics and crack distributions after the debinding process of the green bodies were investigated. The results showed that the distribution of fibers presented orientation characteristics; additionally, the number of cracks after debinding decreased as the fiber content increased and the cracks oriented along the fiber orientation. The mechanical properties of SiO 2 f /SiO 2 ceramics with different fiber contents were also considered. As a result, a compressive strength of 51.2 MPa and flexural strength of 24.3 MPa were achieved for the SiO 2 f /SiO 2 ceramic with 4 wt% fiber, and a sintered cambered structure with a size over 150 mm × 150 mm × 3 mm was fabricated successfully without cracking and deformation for the SiO 2 f /SiO 2 composites with a fiber content of 4 wt% and 6 wt%.

This paper reports a lightweight thermal protection composite with good anti-ablation and thermal insulation properties for service in high temperature environment. The needle quartz fiber (NQF) reinforced phenolic resin aerogel (PRA) composites with surface densification and graded structure were prepared using a mixture of ceramic resin (CR) as the surface layer and phenolic resin (PR) as the internal layer. The Tensile and bending strength of the dense layers were up to 39.22 MPa and 57.22 MPa, respectively. The complete volume rebounded compressive strength of the internal layer was 0.25 MPa and 2.94 MPa in Z and XY directions. In the ablation experiment, the backside temperature peaked at 52 °C within 3 min and 127 °C within 5 min whereas the surface temperature exceeded 1100 °C. Furthermore, the ablated surface remained flat and had a near ablation rate even at a temperature exceeding 1700 °C. The composites which combine insulation and anti-ablation exhibit a prospect in the fields of aerospace and retardant insulation.

In order to improve the mechanical properties of the SiO 2f /SiO 2 composites, the uniform and complete Al 2 O 3 coatings were prepared on the quartz fibers via sol–gel method with aluminum isopropoxide as the precursor. The thickness of Al 2 O 3 coatings increases with concentration of aluminum isopropoxide precursor solution. The Al 2 O 3 coatings fabricated with 10 wt.% precursor solution were uniform and complete, and its thickness was approximately 430 nm. The SiO 2f /SiO 2 composites with Al 2 O 3 coatings achieve higher mechanical strength compared with the SiO 2f /SiO 2 composites without Al 2 O 3 coatings. The flexural strength of SiO 2f /SiO 2 composites increases with concentration of aluminum isopropoxide precursor solution. And the compressive strength shows a slightly decreasing trend with concentration of aluminum isopropoxide precursor solution. The mechanical performance of the SiO 2f /SiO 2 composites fabricated from fibers coated with 10 wt.% aluminum isopropoxide precursor solution was excellent, and its compressive strength was 57.1 MPa, flexural strength was 28.6 MPa. And the reason was that the Al 2 O 3 coatings effectively enhanced the interface isolation between the fiber and the matrix, optimizes the deflection path of the crack and increased the strength of the SiO 2f /SiO 2 composites. The mechanical strength of SiO 2f /SiO 2 composites with Al 2 O 3 coatings was increased after not only short-term but also long-term heat treatment.

Hierarchical and gradient nanostructures are important to exploit the full potential of nanofibers in filtration applications. The introduction of a gradient into carbon nanotube (CNT)/fiber hierarchical structures could result in a change of the particle capturing properties. Here, we show the fabrication of hierarchical carbon nanotube (CNT)/quartz-fiber (QF) filters with gradient nanostructures where the content of CNTs decreases exponentially along the thickness direction of the filters. The loading of catalysts for the growth of CNTs in the QF filter has been achieved using an aerosol technique, which can be carried out on a large-scale. With only 1.17 wt% CNT, the penetration of the CNT/QF filter at the most penetrating particle size (MPPS) has been reduced by one order of magnitude, while the pressure drop only increases about 6% with respect to that of the pristine QF filter, leading to an obvious higher quality factor (Qf) for the CNT/QF filter. More importantly, the service life of the CNT/QF filter with the CNT-rich side downstream has increased by 64% when compared with the pristine QF filter. In contrast, when the CNT-rich side is placed upstream, the service life of CNT/QF filter is only 41.7% of that observed when placing the CNT-rich side downstream. Scanning electron microscopy (SEM) images reveal that the gradient nanostructure of the CNT/QF filter, together with the CNT/QF hierarchical structure play very important roles in the simultaneous enhancement of the filtration efficiency and the service life of the air filters.

Inspired by the Xanthium fruit-like structure, a hybrid hardness and softness structure of carbon nanotubes (CNTs) and polymer chains is considered to be a promising hybrid grafting material. The distributed hard CNTs and soft polymer chains (γ -mercaptopropyl triethyl silane, MPTS) increase the surface roughness of short quartz fibers (QFs), forming a percolated network throughout the surrounding polyurethane (PU) matrix, thereby improving the interfacial interaction between QFs and PU. The modified QFs demonstrate improved interfacial adhesion, higher fiber surface energy, and greater interfacial area failure resistance. The composite fibers exhibited better interfacial adhesion owing to the multi-scale interface structure by CNT@MPTS. In comparison to the unmodified QFs, the interfacial shear force increased by 50.59 %, respectively. Enhancements in the mechanical properties, load transfer in the interface phase, local stress elimination, and inhibition of interphase crack are also brought about by the synergistic effect of CNT and MPTS. The tensile strength of CNT@MPTS modified QFs/PU composite fibers (8% [email protected] %QFPU) rose by 16.72 %. These results indicate a promising route toward developing continuous QFs-based composites with applications as textile-reinforced polymer composites.

Carbon fiber reinforced ceramizable phenolic resin matrix composites (C f /CPR) have been widely used in the field of thermal protection materials. However, the industrial application of the C f /CPR is restricted by its easy oxidation failure under high temperature condition. In this work, a novel antioxidative ceramizable composites modified with AlB 2 and B 4 C (C f -Q f /CPR) were prepared by using quartz fiber-coated carbon fiber (C f -Q f ) as reinforcements via co-weaving technique. The thermal stability, mechanical properties, interfacial phase evolution and anti-oxidation mechanism of the composites were investigated. The residue yield and the flexural strength of the composites after treatment at 1200°C for 15 min were 93.4 % and 62.4 MPa, increased by 5.4 % and 67.3 % compared with those of C f /CPR. Quartz fiber and ceramic protective layer showed synergistic effect to improve the oxidation resistance of carbon fiber and PyC, confirming good high temperature mechanical properties and oxidation resistance of as-received composites.

The preparation of fused silica glass with microstructural patterns has attracted considerable interest, and the process chain of using nano-silica powders mixed with organic polymers to prepare composites for molding, degreasing, and sintering provides a good solution. However, the potential negative effects of organic residues cannot be avoided. In this study, a pattern stencil replication method with silica gel using high-purity quartz fibers as reinforcement is proposed for preparing micropatterned fused silica glass. The microscopic morphology and mechanical properties before and after silica gel drying and the optical properties of fused silica glass obtained by sintering were evaluated via transmission electron microscopy), three-point bending strength test, scanning electron microscopy, X-ray diffraction spectrum analysis, ultraviolet–visible and infrared measurements. The results showed that quartz fiber as a reinforcer could shorten the drying time of the gel and did not degrade the quality of the fused silica glass obtained by sintering. Laser confocal test results showed that microlens arrays were generated by template replication, demonstrating the feasibility of molding fused silica lens arrays with small feature sizes and providing new ideas for the preparation of bulk fused silica glass or micropatterned glass.
