Abstract

In this study, production and mechanical properties of polymer composite materials obtained by using Al2O3, SiO2, MgO and TiO2 hard ceramic fillers were studied. Epoxy resin was used as the matrix material, and four different ceramic powders were mechanically mixed into the resin at 3% and 5% as reinforcement. The mechanical properties of the polymer composite materials were then characterized. For this purpose, flexural modulus and flexural strength of composite materials were determined by using three point bending test and impact toughness of the materials were determined by Charpy impact test. In addition, the hardness values of the samples were determined by Shore D hardness test.

Summary

Introduction

Materials science is a science based on the development of new materials or the improvement of the performance of existing materials. Zhao and Wenbo Luo investigated the effect of nano silica fillers on the mechanical properties of the epoxy composite. They concluded that the elastic modules of the nano SiO2/epoxy composite were greater than those of pure epoxy resins. Ahmad and friends investigated the effect of SiO2 particle shape on epoxy composites and concluded that elongated silica provides the best mechanical properties compared to other shapes [9]. Epoxy composite materials with Al2O3, SiO2, and TiO2 which are frequently used in the literature, and with MgO, which is not used much, were produced to investigate which reinforcement material caused better mechanical properties
