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.

在此SGER奖下进行的研究的目的 是通过实验验证最佳界面涂层 施加到增强纤维上的刚度可以显著提高 复合材料的性能，减少或消除，交叉， 层板开裂 关于互动的新详细信息 在纤维、基质和纤维的界面区域之间， 将产生复合材料。 这将提供一个基本的 理解物理可控的微 纤维增强复合材料，这将 有助于这类材料的最佳设计。
