Experimental study on behaviour of woven composites in thermo-stamping under nonlinear temperature trajectories

Possessing high specific strength and stiffness, woven composites have received great amount of attention as a potential alternative to sheet metals in aerospace and automobile industries. To successfully simulate the manufacturing process, predict the performance of the end products and provide information to aid design of manufacturing processes, the material model should take consideration of various length scales, dynamic characteristics and material properties under different temperatures. Bias extension and tensile tests are among the most important experiments that provide crucial modeling parameters for material characterizations. This paper focuses on experiments under different temperature trajectories, as the forming process itself is often conducted under such conditions.
