Impact testing of carbon fiber-epoxy resin composite with graphene

Abstract

The article presents the state of knowledge in the field of dynamic tests with the use of drop Tower devices of the impact energy of a spherical pivot 18 J. developed structures of composite samples were presented, with dimensions of 150×100 mm, consist of unidirectional prepreg mTm46 / HTS (12k)150-35% RW and adhesive film with and without addition of graphene plane. The impact strength of these composites panels were investigated according to ASTm d7136 / 7136m-15 method. Relationship between impact force versus time during impact test was presented. Relationship between deformation and impact energy in the time of the test was also consulted. The type and degree of samples destruction were observed by the microscope. The effect of graphene addition on the properties of carbon fiberepoxy resin composites were determined. keywords: composite, graphene, composite with graphene, drop tower impact test.
