INVESTIGATION OF C/AL LAMINATE

The fine structure,density,and thermal expansion coefficient of curbon fiber/aluminium/epoxy laminate (CALL) with various volume fraction carbon fiber reinforced epoxy (CFRP) have been revealed.The effect of surface treatment of reinfarced components,the ply design of CFRP/aluminium strctture,the volume fraction of CFRP,and fiber hybridism on mechanical properties of CALL were investigated.The results show that CALL is of low density,low thermal expansion,and high strength.The tensite,flexure,and shear strength of CALL are comparable with the corresponding values of aramid fiber/aluminum laminate(ARALL) and higer than the corresponding values of glass fiber/aluminium laminate (GLALL).
