| Abstract | ||
| The aim of this work is addition of kaolin powder into unsaturated polyester matrix to prepare particulate composites. Samples with and without kaolin exposed for many tests to determine the effect of kaolin contents on the mechanical properties of unsaturated polyester. The results show that, kaolin improved the compression strength by 194% at 7% kaolin, and improved the flexural modulus of unsaturated polyester by 33% at 3% kaolin, and increase the flexural strength by 7% at 5% kaolin, while the impact strength improved by 14% at 9% kaolin and the hardness increased by 4.66% at 3% kaolin. It is concluded that, kaolin acts as binder materials and as particulate reinforcement materials results in improvement in the mechanical properties of unsaturated polyester at relatively low kaolin contents. | ||
