Abstract
A forming process for composite parts comprising pultruding a resin and fiber material through a shortened pultrusion die, exposing the pultruded resin and fiber material to an induction heating coil aligned to be in-line with the pultrusion die to cure the resin and fiber material, wherein one or more of the resin and/or fiber material include a metallic component to facilitate cure via the induction heating coil.
Claims16
A method of making an article comprising:
- feeding a fibrous material from a continuous supply through a pultrusion die, said pultrusion die having a length of less than 1.0 meters, an inductively heated die insert, a tool housing made from a thermally insulating material, and an opening therein into which a reactant may be introduced and feeding said fibrous material at a rate of at least 0.5 meters per minute;
- contacting the fibrous material with a resin when the fibrous material is passed through the pultrusion die, forming a composite mass with a skinned exterior via the inductively heated die insert upon exit from the pultrusion die;
- and
- contacting the composite mass with an in-line induction coil to complete a curing process;
- wherein the resin includes a metallic component to facilitate cure via the inductively heated die insert and the in-line induction heating coil.
