激光处理对CFRP与铝胶接性能的研究
EFFECT OF LASER TREATMENT ON PROPERTIES OF CFRP/ALUMINUM ADHESIVE
摘要
Abstract
Carbon fiber reinforced polymers (CFRP) have been receiving much interest in motivation and aviation fields due to their outstanding properties including lightweight and high strength.However,bonding strength of CFRP between composites and other materials needs to be enhanced because of the strong surface inertia and weak bonding strength.CFRP was treated by lasers with different pulse widths.The modified surface and cementation section of CFRP were characterized by SEM,contact angle test and surface roughness analysis.The results show that the amount of residual resin on CFRP surface decreased with increasing of pulse width,while the surface energy and surface roughness increased.The efficiency of the laser treatment method has been compared with mechanical grinding method through bonding strength and fiber cross section analysis.The bonding strength of CFRP and aluminum for laser treatment method improved 1.95 times and 1.02 times for mechanical grinding method in compassion with the untreated samples.At last,the bonding mechanism and failure mechanism of this dissimilar joint were investigated.关键词
