12 CompositesWorld DESIGN & TESTING JUNE 2015 fber-reinforced composites as well. Tere is work yet to be done on simulating the molding process in areas such as identifying a potential delamination from hand or tape layup and linking this information to curing to determine warpage and residual stresses. Te next critical step is transferring this as-manufactured infor- mation to the structural analysis. Many solutions for continuous- fber composites only pass fber orientation one way, from design to structural or to manufacturing simulations, but the as-manufac- tured information is not yet easily incorporated into the analysis. Solutions for discontinuous-fber composites are further devel- oped by the likes of e-Xstream engineering (Newport Beach, CA, US) and Autodesk, which ofer software able to bring as-manu- factured fber orientations (Fig. 4), fber volume fractions and warpage results from molding simulation to the structural simula- tion, providing more realistic results and valuable insight.

Kenik is the product line manager for Autodesk's composite simulation products and has been involved in both research and development of the technology within those products. Schrader works across simulation products on validation and special projects. (Waltham, MA, US) software can determine weld-line loca- tions, fber orientations from injection or compression molding and warpage due to cooling of a discontinuous-fber-rein- forced composite part. Siemens PLM Software (Plano, TX, US), Dassault Systèmes (Vélizy-Villacoublay, France), and ESI Group (Rungis, France) are able to inform users about ply orientations from a portion of the manufacturing process for continuous FIG. 4 A screen shot from Autodesk's Advanced Material Exchange showing fber orienta- tion being mapped from manufacturing (right) to structural simulation (left).
