Epoxy-based composites moulds are frequently used for wax and polymer materials injection.Tri-phase materials, composed by an epoxy resin, aluminium particles and milled glass orcarbon fibres were produced with better mechanical and thermal performances than the single materials,increasing the competitiveness of the epoxy rapid tooling processes. Charpy Impact testswere employed to obtain a qualitative indication of the composites toughness. The electronic instrumentationof these tests allows a more accurate differentiation of the impact behaviour of theneat and aluminium filled resins, and the tri-phase composites, and consequently, more rigorouslytailor their properties.
