A Study on the Fiber Orientation Effects of Carbon Fiber Reinforced Anisotropy Polymer Hybrid Composites on the Extreme Thin Plate

In this paper we describe an experimental study. This article is a trial production of carbon fiber reinforced anisotropic polymer composite materials of very thin plate sandwich structure consisting of polymer single plate as core and fiber reinforced very thin single plate with X-Y surface anisotropy adhered to each other in optional orientation angle. Bending and tensile characteristics of their mechanical properties are also clarified in this article. It was found that the following; 1) Regarding bending: Calculated value of bending elastic modulus of C.F. prepreg 6 ply, C.F./P.M.M.A./C.F. sandwich and sandwich are similar each other. Material effect of sandwich structure is better than that of C.F. structure. Bending elastic modulus is greatly influenced by orientation angle. 2) Regarding tension: Sandwich structure is inferior to C.F. structure with regard to tensile strength and Young's modulus. Sandwich structure is not effective against tension. Experimental value and calculated value of sandwich structure were similar. Both of strength and elastic modulus are greatly influenced by orientation angle
