Embodiment Construction

[0037] The present invention relates to a method of producing a positive locking load application of rod-shaped fiber composite structures such as tension and compression rods, wherein the hollow body is made of fibers such as carbon fibers and a matrix such as a thermoplastic matrix. For the production of positive locking connections, hollow profiles of fiber-reinforced plastics, such as thermoplastics, are used without structural cores or residual cores. This offers the advantage that the hollow profile can be produced economically as a continuous profile. The invention can be used, for example, in the field of aerospace.

[0038]According to another aspect of the present invention, there is provided a method of generating positive locking load application of a strut bar comprising a fiber plastic composite hollow structure and an outer sleeve. The following method steps can be carried out in any order or simultaneously as long as the fiber plastic hollow structure is at le...

Abstract

The invention relates to a method for generating a tight locking application of a tension rod by means of an outer sleeve (5) through a hollow fiber-plastic structure (2). In the process, a force pushes the hollow fiber-plastic structure (2) at least partially onto at least one force-applying element (3), which is provided with an undercut (6) to form a locking tight connection. The method further comprises locally heating the fibre-plastic hollow structure to a plasticity point of the fibre-plastic hollow structure at least in the region of the undercut of the force application element, and applying at least one outer sleeve (5) to the fibre-plastic hollow structure in the region of the force application element.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 USC § 119 from German Application No. DE10 2019 006 280.9 filed September 5, 2019. The entire disclosure of the above application is hereby incorporated by reference. technical field [0003] The invention relates to a method of producing a positive locking load application of a rod-shaped fiber composite structure, and to a tension rod with a positive locking connection. Background technique [0004] The competitiveness of rod-shaped fiber composite structures or strut-and-tie rods in the aerospace industry is primarily determined by their weight, their manufacturing costs, their behavior in the event of impact damage, and their resistance to bending and their tensile strength. These components are mainly produced based on a thermosetting matrix combined with high-performance carbon fibers. The use of a thermoplastic matrix in combination with a suitable process for producin...
