Description

technical field [0001] The invention relates to the surface modification of poly-p-phenylene benzobisoxazole fibers, in particular to a surface modification treatment device for continuously treating poly-p-phenylene benzobisoxazole fibers. Background technique [0002] Due to its light weight and high strength properties, composite materials have a growing demand in high-tech fields such as aviation, aerospace and national defense. Composite materials are multiphase systems composed of matrix materials and reinforcement materials. Composite materials that use polymer as a matrix as structural members mostly use fibrous materials, especially continuous long fibers, as reinforcing materials. As a new type of reinforcing material, poly-p-phenylenebenzobisoxazole (PBO) fiber has attracted much attention not only for its excellent mechanical properties, but also for its good heat resistance and high oxygen resistance index. "Superfibers of the 21st Century". However, despite ...

Problems solved by technology

Some of these methods have excessively lost the mechanical properties of the fiber itself (chemical oxidation method) while improving the surface properties of PBO fibers, and some have serious degradation effects, that is, the modification effect decreases with time (plasma treatment method) , radiation treatment method), some treatment effects are not obvious and the treatment speed is slow and the efficiency is low (biological treatment method). At the same time, most of these methods are in the experimental stage and cannot continuously process PBO fiber filaments, which reduces production efficiency , can not achieve the purpose of industrial production
