DEFINITION

Classification: 264/259

(under subclass 241) Processes in which a molding material is shaped or formed against a preform and said shaped material remains united with the preform to constitute a composite article.

(1) Note. Where the preform and the shaping material are the same composition so that the product is homogeneous and cannot be called composite, the patent will not be placed herein but will be classified in the appropriate subclass based on the manipulative steps involved.
