抄録

A new process of internal activation of glass fiber reinforced thermoplastic polymer (GFRTP) of Polypropylene (PP) was achieved by homogeneous low energy electron beam irradiation (HLEBI) to the interlayered glass fiber chopped strand mats (GF-CSM) prior to assembly. Panels were fabricated by hot-press consisting of 5 HELBI-treated GF-CSMs between 6 untreated PP sheets. HLEBI improved the Charpy impact value (a_uc) of the internally activated GFRTP. HLEBI from 0.22 to 0.86 MGy mostly improved the a_uc at each accumulative probability of fracture (P_f). Based on the 3-parameter Weibull equation, the a_uc value was defined as the statistically lowest impact value, a_s estimated as the a_uc at P_f = zero. The highest a_s values at more than 87 kJ/m² were found for GFRTP irradiated at 0.65 MGy which appears to be at or near the optimum HLEBI dose. Strengthening the adhesion force at the extremely broad surface area of the fibers increased interfacial friction force to prevent fiber pull out, fiber/matrix debonding and crack generation in the hard to adhere PP matrix GFRTP, resulting in increasing a_uc of GFRTP with glass fiber surface-activated by HLEBI.
