Abstract

The development of alternative materials or other materials as a substitute for metal materials is necessary to minimise the shortcomings that exist in them. One of the materials that can be utilised as an alternative to metal materials is composite materials. The purpose of this study is to determine the composition of composites made of glass fibre and nanosilica as reinforcement and unsaturated polyester resin as the right matrix for flexural testing using the Taguchi method.In this study, there are three factors and each factor has three levels with the final output being the determination of the optimal level setting. The data required in this research is composite flexural strength test data and the test results will be analysed using ANOVA.The results of ANOVA calculation of SNR values showed that each factor and interaction between factors had a significant effect on the flexural strength of the composite. The results showed that the optimal setting level was obtained from composites made from (A1), (B1) and (C3).
