Method and Apparatus for Continuous Production of Endless Fiber-Reinforced Rotationally Symmetric and/or Non-Rotationally Symmetric Components with Varying Cross-Sectional Profiles by Means of Orbital Winding Technology

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a method and apparatus for continuously manufacturing endless fiber-reinforced components—both rotationally symmetric and non-symmetric, with varying cross-sections—using orbital winding technology. A stationary winding core moves forward while a rotating tape storage system lays thermoplastic, fiber-reinforced tape around the core under controlled heat and pressure to form the desired part.

Patent Abstract

Das Erfindung umfasst das Bereitstellen eines die wesentlichen die Außenkonturen des gewünschten Bauteils aufweisenden Wickelkerns, der in der Orbitalwickelanlage nichtrotierend, jedoch eine Vorschubbewegung ausführend ausgebildet ist. Um diesen wird ein faserverstärktes, thermoplastisches Tapematerial von einem orbital rotierenden Tapematerialspeicher mittels orbitaler Lege- und Wickeleinheit als Konsolidiermodul bei zeitgleichem Aufheizen des Wickelmaterials und mit einem konstanten Druck und unter Beibehaltung einer konstanten Tapematerialspannung aufgelegt.
