Influence of Process Parameters on Mechanical Properties of Composites Fabricated by VARTM Process

Article Preview

Abstract:

Some glass fiber/vinyl ester resin composite laminated panels were fabricated by varying levels of resin temperature, resin bleeding time and vacuum level. Interlaminar shear tests were performed to investigate the effects of process parameters on interlaminar shear strength (ISS) of laminated panel. The optimization of processing parameters was also conducted by employing the method of Artificial Neural Networks (ANN) in order to improve the ISS of laminated panel. The optimized test results are: resin temperature 30°C, resin bleeding time 7s, vacuum level 97KPa, and the result of ISS is 41.2MPa
