Method of making composite structure for superplastic forming.

摘要

The present invention provides a method of superplastically forming an article by explosive bonding two or more components (16, 18, 20) together to form a composite article and superplastically forming the resulting article. The explosive bonding involves spreading a layer of salt (12) to prevent the components bonding to the supporting structure (10)during the explosion and coating the external surfaces of the components with an adherent rubber or plastic coating (26, 28) to prevent surface degradation during the explosion. <IMAGE>
