Résumé : |
Short fiber-reinforced plastics are used for many technically demanding applications. For efficient development processes and high product quality, their anisotropic material properties must be factored into the design cycle. A simple approach often taken is to reduce the material stiffness. However, a more accurate approach is to consider the effective fiber orientation. This article discusses the pros and cons of both approaches. |
