Viscoelastic properties of bioinspired asymmetric helicoidal CFRP composites

Abstract A dynamic mechanical thermal analyser (DMTA) was used to develop insight into the properties of bioinspired asymmetric helicoidal carbon fibre reinforced plastic (CFRP) composites as a function architecture using inter-ply stacking angles 0° (UD), 0/90° (cross-ply), 5°, 15°, 10°, 20°, 25° and 30°. Here, we show that CFRP are linearly correlated their oriented ply fractions between 45° off loading axis. We furthermore provide evidence from tan- δ curves heterogeneous materials with separate viscoelastic phases glass transition temperatures, resulting architectures these composites. Inter-ply finally noted critical factors affecting extent macromolecular mobility within helicoidally stacked continuous Graphical abstract
