Abstract

A composite material was prepared with carbon fiber (CF) and a matrix of phosphate (as named ACP) mainly consisting of aluminum phosphate. CF was used in the form of felt cloth. Prepreg was made with CF and ACP, which was laminated and formed under pressure in a hot press into a composite. The prepreg was pretreated by drying at 80°C to form a compact matrix and to increase the adhesion between laminated prepregs. At the hot press treatment thorough removal of water was tried by using absorbent sheet and release sheet to form a compact structure. Consequently, porosity of CF/ACP composite decreased, and its bulk density and bending strength increased. SEM observation showed the formation of vitreous and compact matrix. Besides, adhesion between prepregs and shear fracture resistance were improved.
