Abstract

This study focused on VaRTM which is one of low-cost processing method, and intends to reveal the effect of to insert thermoplastic veil between carbon fiber on molding quality and strength property. Molding quality was assessed by measurement of the fiber volume fraction; the compression strength was determined by doing non-hole compression (NHC) and compression after impact (CAI) test. And design of experiments and analysis of variance were introduced to understand the effect of processing condition to the manufacturing quality and the compression strength properties. With the results obtained, it is confirmed that molding quality is affected by process condition. The CAI test clearly showed the increase in strength as a result of melt-infiltrated of the thermoplastic veil. NHC strength is significantly affected by molding quality. The effect of process condition change can be explained by introducing the design of experiments and the analysis of variance.
