Strength Optimization of Material Systems Containing Cylindrically Shaped Coated Fibers

根据这项SGER奖进行的研究的目的是通过实验验证，在增强纤维上应用具有最佳硬度的界面涂层可以通过减少或消除交叉铺层开裂来显著提高复合材料的性能。将生成关于纤维、基质和复合材料界面区域之间相互作用的新的详细信息。这将从根本上理解物理可控的微观参数对纤维增强复合材料的影响，这将有助于这类材料的优化设计。

The purpose of the research to be performed under this SGER award is to verify experimentally that interface coatings of optimum stiffness applied to reinforcing fibers can significantly improve the performance of composites by reducing, or eliminating, cross- ply cracking. New detailed information on the interaction between a fiber, the matrix and the interphase regions of composites will be generated. This will provide a fundamental understanding of the influence of physically controllable micro- parameters on fiber reinforced composite materials, which will aid in the optimal design of this class of materials.
