Rapid forming of woven composites has the potential to open up a large number of new applications to structural polymer composites. However, there are still many unknowns for these relatively new material systems, both in proper methods to experimentally obtain material properties and in analysis and simulation of forming behaviours. Systematic benchmark tests on the material characterization of woven composites and the modelling of its forming process are clearly needed to accelerate the implementation of these promising processes. This report is the first report of an international cooperative benchmark effort, focusing on material properties. The experiments include shearing tests (picture frame tests) and bias extension tests for both balanced and unbalanced fabrics. These experiments play an important role in the study on woven fabric composites, by providing data for material characterization and verifying models.
