Quartz fiber: a key material for aircraft thermal insulation

Performance Characteristics of 1–6 mm Chopped Aramid Fibers

"1414 staple fiber" typically refers to para aramid chopped fiber. This type of chopped aramid fiber is produced by cutting high strength aramid filaments using a specialized process, with the fiber length typically controlled within the range of 1-6 mm. Possessing both high modulus and excellent heat resistance, these fibers are easily and uniformly dispersed within resins, rubbers, and engineering plastics thanks to their superior dispersibility thereby enhancing the overall mechanical properties of the final products.

Quartz Fiber Chopping Technology Continues to Advance, Ushering in New Opportunities

Wet-laid Aramid Fiber Nonwovens Embrace New Growth Opportunities

Distinguished by their high-temperature resistance, flame retardancy, high strength, and excellent insulation properties, aramid fiber wet-laid nonwovens are widely utilized across industries such as industrial filtration, new energy vehicles, electrical insulation, and rail transit. Furthermore, they are poised to achieve significant breakthroughs in fields including thermal insulation, anti-static applications, thermal conductivity, and composite reinforcement.

Performance advantages of basalt fiber wet nonwoven fabric

Basalt is a volcanic extrusive rock and one of the most widely existing and distributed minerals on Earth. The continuous fiber produced from it represents a qualitative leap in fiber quality compared to ordinary rock wool. Its high elastic modulus, high thermal stability, and excellent acid and alkali resistance have led to its widespread application.

Technical Analysis of Carbon Fiber Wet-Laid Nonwovens

Carbon fiber wet-laid nonwoven fabric is a porous material primarily made from chopped carbon fibers, which are evenly dispersed in an aqueous medium and prepared through a wet-laid web-forming process akin to papermaking. This process effectively mitigates fiber agglomeration issues, achieving a three-dimensional uniform distribution of fibers.

Quartz Filaments: The "Heat-Resistant, Wave-Transparent Barrier" for High-End Equipment

Quartz fiber is prepared using high-purity quartz sand (with an SiO₂ content of ≥99.95%) as raw material, through processes such as melt drawing, surface treatment, and composite molding. It is a specialized inorganic fiber material that combines high-temperature resistance, low dielectric loss, high electrical insulation, and thermal shock resistance.

Research on the Preparation Process and Properties of PPS Fiber Wet-Laid Nonwovens

PPS fiber wetlaid nonwoven fabric is produced by opening and dispersing PPS staple fibers in water to form a uniform suspension slurry. The slurry is then transported to the forming wire section for dewatering, resulting in a wet fiber web, which is subsequently reinforced and shaped
