  • V-Shape Molding and Mechanical Characterization of Continuous Carbon Fiber Reinforced PA6

抄録

<p>In this paper, in order to investigate the mechanical property of V-shape carbon fiber reinforced thermoplastics (CFRTP), four point bending tests were conducted. The test was carried out using similar testing tool to ASTM D 6415. Also, step-by-step four point bending test with acoustic emission (AE) measurement were performed and the damage process were characterized. CFRTP plates were molded with a bending-type V-shape mold which has angle 90°. CFRTP studied was plain woven carbon fabric reinforced polyamide 6 (PA6). Pre-consolidated laminates were preheated above melting temperature of PA6 in a hot press machine, and then pressed after transferred to the V-shape mold. As a result, the molding temperature 250 °C specimen indicated maximum interlaminar tensile strength about 44 MPa. Also, the difference between damage process and modes occurred with change of molding temperature. The critical damages of 200 °C specimen was weft fiber yarn cracks and 250 °C specimen was interfacial peeling between weft fiber yarn and warp fiber yarn.</p>
