Liu, S. (author), Sinke, J. (author), Dransfeld, C.A. (author)The bias-extension test is one of the test methods to characterise the intra-ply shear behaviour of continuous fibre reinforced composites including fabrics and unidirectional (UD) materials.

Gülmez, D.E. (author), Sinke, J. (author), Dransfeld, C.A. (author)Discontinuous tape composites have considerable attention due to their high formability and tailorable structures. Despite their advantages, this discontinuity leads to complex structures and makes it difficult to predict their mechanical properties. On the other hand, they have high orientational and dimensional sensitivity, which causes...conference paper 2022
