AB  - We present a new hybrid CFRP concept, aimed at increasing the energy absorption capacity of the material by diffusing damage through-out the laminate. To achieve this, we combine thin-ply CFRP layers, cut into interlocking tiles, with titanium interlayers. Uniaxial tension tests and bending tests on a preliminary design iteration showed that damage initiation and initial propagation were successfully achieved, but damage propagation localized during further loading. Final failure was triggered by strain concentrations in the titanium layers, which caused the titanium failure strain to be locally exceeded. The key to achieving higher laminate ultimate strain is to prevent or ameliorate these strain concentrations in the titanium layers.
