Energy absorption capacity of braided frames under bending loads

  • The energy absorption capacity of braided composite frames under bending loads was studied by conducting quasi-static four-point-bending tests. As specimen geometry C-shaped frame segments where chosen which show the typical failure behaviour of frames with open cross section, such as local buckling and crippling. The braiding manufacturing process offers the possibility to influence the fracture mechanics by a local hybridization of the braider yarns. Different hybridization concepts were investigated to identify design principles for braided frame structures with enhanced energy absorption capacity. The test results show that the post-failure energy absorption of braided frame segments can be significantly increased by a local modification of the braid architecture.
