In this year, the research orientation was still going on the evaluation of the micro structures of randomly oriented strands (ROS) composites fabricated with carbon fiber reinforced thermoplastics (CFRTP) as well as the mechanical properties verification and the corresponding simulation methods.Two 3D X-ray micro CT methods based on different image processing algorithms are studied and the acquired internal geometry information are applied to two different mechanical modeling processes. The combination of X-ray micro-CT methods and analytical simulation models open the new ways for comprehensive solution methodologies of discontinuous CFRTP analyses with criterions and suggestions of corresponding applications.

今年，碳纤维增强热塑性塑料（CFRTP）随机取向股线（ROS）复合材料的微观结构评价、力学性能验证及相应的模拟方法仍是研究方向。研究了基于不同图像处理算法的X射线显微CT方法，并将获得的内部几何信息应用于两种不同的机械建模过程。X射线显微CT方法与解析模拟模型的结合，为不连续CFRTP分析的综合求解方法开辟了新的途径，并提出了相应的应用准则和建议。
