Local strain re-distribution and stiffness degradation in cross-ply polymer composites under tension
Individual aramid Kevlar® 49 fibers were embedded into the 0° ply of transparent cross-ply glass fiber reinforced polymer (GFRP) laminates and used as Raman sensors for the monitoring of the local strain field due to matrix ...
Effect of Off – Axis Matrix Cracking on Stiffness of Symmetric Angle-Ply Composite Laminates
Matrix cracking models developed for cross-ply composite laminates cannot easily be applied to more complicated geometries. In this paper a detailed analysis of the effect of matrix cracking on the longitudinal Young’s ...
