Method for the production of hollow components of composite fiber materials in tube construction, film tube and a manufacturing method for a film tube

摘要

Method for the production of hollow components with the use of a tubular foil (1) and a forming tool (3), comprising the steps of:a) introducing a plastic - material in the region of an inner - surface (4a, 4b) of the forming tool (3),b) forming of the material to the inside - surface (4a, 4b) of the forming tool (3),c) introduction of a tubular foil (1) in the form tool (3), so that the material between an outer surface of the tubular foil (1) and the forming tool (3) is positioned,d) expansion of the tubular foil (1) with the aid of pressure and / or vacuum,e) introduction of a pressure (p) by means of atmospheric pressure and / or heating of the forming tool, so that the material completely or partially melted and shape of an internal, - contour of the forming tool (3) and an outer contour of the expanded film tube (1) is adapted to,characterized byForms of the tubular foil (1)) in the manufacture of a continuous material, prior to being introduced into the forming tool (3) in step c) in such a way that it in a sectional plane perpendicular to its longitudinal extent, a contour with a plurality of distributed over its circumference in the direction of its longitudinal extension, embossed indentations (e) comprises.
