Friction Properties of Steel Fibre Reinforced Epoxy Composites Used in Moulding Blocks of Hybrid Moulds

Abstract:

Rapid tools for injection moulding are often produced by casting of epoxide filled composites. The moulding blocks obtained in this way are likely to undergo wear especially at the surfaces of the moulding cores during the ejection phase. In this study, tribological properties of epoxide composites containing different volume fractions of short steel fibres used in moulding blocks were assessed. Friction tests with the composites and moulded polypropylene were carried out with a prototype equipment that reproduces the actual ejection phase of injection moulding. The friction data were interpreted in terms of the roughness and compared with the microscopic features of the epoxy composite surface.
