OPTIMIZATION OF VIP PARAMETERS OF THE MECHANICAL PROPERTIES OF GFRP COMPOSITE

ABSTRAKT
In this paper, the optimization of vacuum infusion process (VIP) parameters of the mechanical properties (modulus and tensile strength) of glass fiber reinforced plastic (GFRP) composites has been investigated. The optimization was done using 20 samples that were designed by the response surface methodology (RSM) method using such process parameters as the viscosity of 400, 550, and 700 g/cm·s, glass fabric surface weight of 200, 300, and 400 g/m2, and fabric angle of 0°, 30°, and 60°. The results show that with increase in the resin viscosity, the strength and modulus of the samples increase by 7.9% and 5.1%, respectively. On the other hand, increasing the fabric surface weight reduces the strength by 11.5% and the modulus by 16.1%. Finally, it is shown that the reinforcement angle has the highest impact on the mechanical properties of the composite sample such that on increase in the reinforcement angle from 0° to 45°, the strength and modulus decrease by 77.3% and 47.7%, respectively, and increase again at higher angles.
