Evaluation the Mechanical Properties of Kaolin Particulate Reinforced Epoxy Composites

Epoxy resin has many chemical features and mechanical properties, but it has a small elongation at break, low impact strength and crack propagation resistance, i.e. it exhibits a brittle behavior. In the current study, the influence of adding kaolin with variable particle size on the mechanical pro...
