Abstract
A composite structure and method of making the composite structure are disclosed. A reinforcing fabric such as fiberglass is mechanically attached, for example, by stitching to a non-woven polyester fabric. The attached fabrics are placed in a mold with the non-woven fabric facing the inside of the mold. A self-expanding, self-curing foam is filled into the mold in an amount sufficient so that upon expansion in the closed mold, the foam penetrates into the interstices of the non-woven fabric which upon curing forms a bond therewith. The resulting structure can be used in a number of applications wherein the reinforcing fabric is later impregnated, for example, with a resin, and allowed to cure. Typical use of such a structure is as a stringer in fiberglass boat construction.
