发明名称 Method of forming an expanded composite
摘要 Process using low to medium temperature thermoset epoxy composite materials and an expandable epoxy matrix material to efficiently form high strength composite parts of divers shapes in a single-one-step process. The composite material is placed within the periphery of a mold and expandable epoxy matrix material is placed between the layers of the composite material either before or after closing the mold and, then, subjecting the mold and its contents to heat which activates the epoxy resins in both the composite material and the matrix material causing the matrix material to expand thereby compressing the composite material in order to produce a competent composite part.
