Abstract
A thermosetting epoxy resin includes particles of magnetite and conductive carbon to act as microwave susceptors. A composite material comprises a thermosetting epoxy resin matrix phase with particles of magnetite and a carbon fibre reinforcement phase. A mould for a composite article comprises a mould body made from a material that is substantially transparent to microwaves with a surface or rear surface layer including microwave radiation absorbing material.
Claims25
A thermosetting epoxy resin including particles of magnetite and particles of conductive carbon material.
A composite material comprising a thermosetting epoxy resin matrix including particles of magnetite and carbon fibre reinforcement.
A method of forming a composite material article comprising the steps of providing a matrix material comprising at least a thermosetting epoxy resin and magnetite particles, providing a mould of substantially microwave transparent material, providing a carbon fibre reinforcement material, laying up the matrix material and the reinforcement material in the mould and applying microwave radiation to the laid-up material to effect thermosetting of the resin.
A mould for moulding a composite material article comprising a mould body formed of material which is substantially transparent to microwave radiation and a tool face having microwave radiation absorbing material on or adjacent the working surface thereof.
A method of making a mould for moulding a composite material article comprising the steps of providing a mould body of substantially microwave transparent material, providing a tool face and incorporating into the tool face or applying to the working surface of the tool face, microwave radiation absorbing material.
