In the joint project STRONG, A+ Composites, in cooperation with SCHLIESSMEYER GmbH, is developing a process for inserting UD tapes into injection-molded parts in a load-appropriate and reliable manner.

In several work packages, existing and innovative methods are being tested and options are being investigated for injecting continuous fiber-reinforced thermoplastic tapes into the injection molding process in a way that is appropriate to requirements and loads. Processing tests using different material combinations are intended to show the range of materials and different tapes that can be used.

​

The most promising of the methods tested are selected and suitable materials are developed so that test specimens can be produced for testing and simulation. It is particularly interesting to see how complex geometries can be reinforced. Based on the results, the processes are further developed and two injection molding tools are manufactured. The tools are then used to produce demonstrators.

​

The project offers great potential to give the injection molding process new degrees of freedom. By using UD tapes to stiffen the components, plastic can be saved and new designs can be realized. New product classes with higher requirements become possible, or product differentiations can be achieved simply by using different UD tapes. This means that no new injection molding tools need to be produced. Differentiation is achieved through the performance of the tapes used.
