Structure and performance have extremely important influence to the performance of PEMFC.Since carbon fiber surface is very smooth, therefore beaten in laboratory
Slurry cannot pass through mashing as plant fiber and make its surface wire-dividing broom purification, between fiber and fiber can not as plant fiber that
Sample forms paper by forming Hydrogenbond.Therefore must be added to adhesive, it can just make page that there is certain intensity.It is more at present
Adhesive using phenolic resin as carbon fiber paper, but that there are brittleness is big, poor toughness, hardness are high, heat resistance for pure phenolic resin
The insufficient, disadvantages such as intensity is low, extreme influence material mechanical performance, therefore, it is necessary to be modified to phenolic resin.In carbon fiber
It is made of paper it is standby during, resin impregnated carbon fiber body paper and resin solidification mold process can generate carbon fiber paper performance to Guan Chong
The influence wanted, during resin-molded, solidification temperature, molded curing pressure will affect the performances such as carbon fiber paper thickness, density.
Meanwhile guarantee phenolic resin curing is complete before carbonization, generates hole in carbon fiber paper, the probability of crackle also can accordingly reduce,
Resin can give full play to cohesive action in carbon fiber paper, and then improve the processing performance of carbon fiber paper.Solidify in carbon fiber paper
During, solidification temperature too low curing time extends or solidification is incomplete, declines phenolic resin carbon yield.Solidification temperature mistake
Height, Resin Flow is too big, not can guarantee resin content.Studies have shown that graphene is added in resin system, both played
The effect of reinforcement can improve the electric conductivity and mechanical property of material again.Phenolic resin is modified using anacardol, can be shown
Write the toughness and heat resistance for improving material.It there is no the report by graphene and anacardol while phenol-formaldehyde resin modified at present.
