Abstract

This study explores the feasibility of improving damage resilience around structural features in composite components through varying (a) the internal geometry of the reinforcement and (b) matrix properties. The gradients in fibre architecture are realised through varying the braiding angle in triaxial braided sleeve. Introducing matrix gradients is implemented through a novel Liquid Resin Print technique which is applied through precise point-wise injections of dissimilar brittle and tough polymers into dry textile preforms prior to infusion. Open hole tensile tests are used to assess the damage development in reference and modified materials.
