Abstract (EN):
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 or
carbon fibres were produced with better mechanical and thermal performances than the single materials,
increasing the competitiveness of the epoxy rapid tooling processes. Charpy Impact tests
were employed to obtain a qualitative indication of the composites toughness. The electronic instrumentation
of these tests allows a more accurate differentiation of the impact behaviour of the
neat and aluminium filled resins, and the tri-phase composites, and consequently, more rigorously
tailor their properties.
