STUDY AND APPLICATION OF THERMAL EXPANSION MOLDING OF COMPOSITE

The principle and molding process of the thermal expansion technology of the composite are briefly introduced. The material property, design and manufacture of the thermal expansion core mold are tested, the influencing factors on the expansion pressure are analyzed and the technology is compared with the autoclave molding process. The core mold made of thermal expansion silicon rubber is used with steel mold to mold CF composite products with good result. The research showed that this technology was suitable for the global co-curing molding of the multi-cavity composite products.
