Abstract
Epoxide filled composites are being increasingly used for mouldings blocks of hybrid
injection moulds. The filling is sought for improving both mechanical and thermal properties that
are relevant for the mould performance. In spite of several works investigating the particulate filling
of resins, there are only a few reports on fibre reinforcement. Composites based on an epoxy system
with varying volume fractions of short steel fibres (SSF) were investigated. The mechanical
properties were determined for each composite, and the topography of the fracture surfaces was
analyzed by SEM. The mechanical properties of the epoxy filled composites were also compared to
commercial particulate composites that are used for producing casting moulds. In spite of the SSF
being more difficult to mix that the usual metal particulate fillers, it was found that the resulting
composites show some improvement in the mechanical properties.
