[0055] Example 2
[0056] First step, short cut carbon fiber chemical plating:
[0057] The commercial T800 carbon fiber is used, and then the screen is used to sieve by 400 mesh screen. The short-cut carbon fiber is taken under the sieve to obtain a short cut carbon fiber having a length of 30 μm, and the chucking carbon fiber is chemically copper-plated, and the process comprises: front treatment → Sensitization, activation → restore → plating, wherein the pre-treatment is soaked using a burning method and an organic solvent. The specific process is 1 h in a heating furnace of 420 ° C, then uses acetone to immember 1 h, then use alcohol ultrasound 15 min, dry After the cryogen is roughly rinsed, then repeatedly rinsed all residual nitric acids, then alcohol dehydrate, and then dried by alcohol; sensitizes, the activation of carbon fibers are placed in sensitization - the mechanical stirring for 15 min. Sensitization - The formulation of activated liquid is chlorinated 30g / L, a...
