Entfernbarer Kern zur Herstellung rohrfoermiger Strukturen aus Faserverbundwerkstoffen
摘要
A removable core for use in the production of tubular structures from fibre reinforced resin materials. The body of the core is composed of a foam material which softens or collapses under the action of heat sufficient to cure the resin material but is hard and cross-sectionally dimensionally stable under less heat than that. The core is provided on the outside with a heat shrunk plastic tube or hose which closely embraces the foam body and serves as a coating therefor, thereby enhancing the rigidity and stability of shape of the core and imparting thereto a smooth surface.
