Carbon fiber felt needle punching is to open, comb and lay short fibers into a fiber net, and then reinforce the fiber net into cloth through needles. The needles have hooks and thorns, which repeatedly puncture the fiber net. The hooks and fibers are reinforced to form needle-punched carbon fiber raw felt. The production of carbon fiber felt by needle punching is to reinforce and hold the fluffy fiber net through the puncture action of the needle punching machine to obtain strength.<\/p>

The fiber net is repeatedly punctured by a needle with a barb on the edge of a triangular cross section (or other cross section). When the barb passes through the fiber net, the surface and local inner fibers of the fiber net are forced to penetrate into the fiber net. Due to the friction between the fibers, the original fluffy fiber net is compressed. When the needle withdraws from the fiber net, the inserted fiber bundles break away from the barb and remain in the fiber net. In this way, many fiber bundles entangle the fiber net so that it can no longer restore its original fluffy state. After many times of needle punching, quite a number of fiber bundles are pierced into the fiber net, so that the fibers in the fiber net are entangled with each other, thus forming a carbon fiber raw felt with a certain strength and thickness. The original carbon fiber felt is then pre-oxidized and carbonized to obtain carbon fiber felt (production process of PAN-based carbon fiber felt).<\/p>

Carbon fiber felt has high axial strength and modulus, low density, ultra-high temperature resistance in non-oxidizing environment, good fatigue resistance, acid and alkali resistance, high temperature resistance, good x-ray transmittance, good electrical and thermal conductivity, and good electromagnetic shielding properties. It is increasingly used in industry, medical care, environmental protection and other fields.<\/p>

Carbon fiber needle punched preforms are made of carbon fiber cloth with optimized angle plying, combined with carbon fiber short fiber filling, and connected as a whole through special processes. C\/C composite materials are made by vapor deposition and compounding, which is a lightweight, strong and durable carrier structure. Common specifications include regular parts such as flat plates and pots, as well as special-shaped parts such as guide tubes and crucibles.<\/p>

Carbon fiber needle punched preform is a kind of C\/C composite material preform. The forming process of needle punched preform is to use fiber mesh as the raw material for needle punching, and use a special needle with inverted hooks for needle punching to form a quasi-three-dimensional mesh structure reinforcement with certain strength in both plane and interlayer. Needle punched preform overcomes the weak interlayer strength of 2D laminated preform, and at the same time overcomes the weakness of 3D woven preform, which is complex process and high cost.<\/p>

Carbon fiber preforms are made of high-strength carbon fiber, carbon fiber cloth, and carbon fiber felt through repeated layering and needle-punching. They are filled with short fibers and have a certain density and firmness. The products include various hot field crucibles, guide tubes, crucibles, insulation barrel preforms and flat plate preforms. The products are C\/C value-compounded into lightweight, sturdy and durable hot field components. They can also be processed into high-speed rail, automobile brake discs, fasteners and special-purpose products.<\/p>
