Abstract

This paper experimentally investigated the effect of recycled carbon fiber reinforced plastic (rCFRP)'s initial orientations and fiber-to-polymer ratios using vibration for fiber alignment. The studied rCFRPs were placed on top of a filter plate (with rectangular holes) and vibrated for fiber alignment. The rCFRPs were then mixed with the matrix material (Polypropylene) at different ratios (25/75, 20/80, and 15/85) by heating. The alignments of fibers in the mixed polymers were analyzed by using image processing software. Tensile testing of fibers at 0°, 45°, 90° to the pulled direction was conducted to evaluate the mechanical properties. The results showed that a 90° orientation and a fiber-to-polymer ratio of 20/80 provided the highest tensile strength values.
