ESI全球论坛2014年开发用于注塑和BMC/SMC模塑的CAE软件包括短/长纤维增强材料作者：Ryo Nakano和Katsuya Sakaba，CAE业务部，东丽工程株式会社Pierre Marquette，COE复合材料制造，ESI集团从轻量化设计的角度，不同长度的玻璃纤维和碳纤维增强塑料是像BMC/SMC一样在注塑和压缩成型方面很有前途的方法。特别是长玻璃纤维/碳纤维有望实现模压制品的高弹性模量和高强度性能。无论是短纤维还是长纤维，成型过程中纤维的取向和分布都是塑料件设计的关键。由于长纤维具有弯曲和相互作用的特性，建议对传统的纤维取向分析方法进行修正，使之能够正确地估计短纤维取向。此外，传统方法不能根据纤维沿空腔部分的分布来预测纤维体积分数。在CAE软件“3D TIMON”中直接模拟短/长纤维的纤维动力学，不仅可以估计纤维的取向，还可以估计纤维的弯曲、断裂和分布。BMC/SMC成型CAE也是最新发展起来的，具有较高的实用性。传统的注塑CAE和BMC/SMC成型CAE已经与直接纤维模拟联系在一起。最后，通过成型过程模拟得到的纤维取向可以与材料性能评估和结构分析联系起来。
ESI Global Forum 2014 Development of CAE software for injection and BMC/SMC molding including short/long fiber reinforcement Authors: Ryo Nakano and Katsuya Sakaba, CAE Business Div, Toray Engineering Co., Ltd Pierre Marquette, COE Composites Manufacturing, ESI Group From a view of the lightweight design, glass fibers and carbon fibers reinforced plastics with various lengths are a promising way in injection molding and compression molding like BMC/SMC. Especially, long glass/carbon fibers are expected to realize high performance in elastic modulus and strength of molded parts. For both short and long fibers, fibers orientations and distribution in molding process is a key for plastic parts design. Conventional fibers orientation analysis which can correctly estimate short fibers orientation is suggested to be modified for long fiber because long fibers characteristics of bending and interacting. Also, fibers volume fraction by fiber distribution along cavity portion cannot be predicted by conventional methods. Direct simulation of fibers dynamics of short/long fibers in CAE software “3D TIMON” can be applied to estimate not only fibers orientation but fibers bending, breaking and distribution. BMC/SMC molding CAE which has high applicability to practical part is also newly developed. Conventional injection molding CAE and BMC/SMC molding CAE have been linked with direct fibers simulation. Finally, fibers orientation obtained by molding process simulation can be linked to material property estimation and structural analysis.
