Hollow composite product e.g. tank, manufacturing method, involves blowing interior of thermoplastic parison for plating assembly against mold, where assembly is formed by thermoplastic parison and structure

摘要

The method involves extruding a thermoplastic parison (1) placed in a mold (3) using an extrusion blow molding machine (2). A heated composite structure (4) is intercalated between the parison and the mold, before sealing the mold, using an intercalating unit. The interior of the parison is blown for plating an assembly against the mold using a blowing unit, where the assembly is formed by the thermoplastic parison and the structure. The structure is formed by composite wires constituted of filament such as glass filament. The product is made of reinforcement material such as long fiber. An independent claim is also included for a device for manufacturing a hollow composite product.
