Abstract
An innovative winding process has been developed for the production of lightweight truss structures by autonomously joining composite profiles. The winding device consists of an open ring with a rotor-stator design and is moved by a vertically articulated robot. The robot allows a high degree of flexibility and design variety in the winding patterns. In order to achieve a high joint strength, however, it is necessary to provide a flange on the transverse profile which can be wound around to create a form-fit. This flange is very complex and expensive to manufacture and cannot be individually adapted. In order to provide a better flange to join these cost-effective pultruded profiles, 3D printed dual-curing epoxy joining elements are being developed. These elements are first manufactured using the digital light synthesis (DLS) printing process, which results in a semi-rigid, but only partially cured part. The printed joining elements can then be robotically wound with pre-impregnated fiber tows (towpreg). The assembly is then heated to activate the second curing reaction and co-cure the two materials, resulting in a permanent, void-free bond. Combining these two technologies enables the economic mass production of light-weight composite truss structures, aiding in an increase in resource efficiency in the corresponding fields of application such as the construction or transportation industries.
