引言传统纤维复合材料的高性能只体现在平面型的增强材料上(一维或二维),由于基体的性质必然决定了材料在垂直于平面方向强度的限制。为了克服这种限制,人们已设计了各种多维增加纤维强度的方法。这包括 Introduction The high performance of traditional fiber composites is only reflected in planar reinforcements (one-dimensional or two-dimensional), since the nature of the matrix necessarily determines the strength of the material in the direction perpendicular to the plane. To overcome this limitation, a variety of multi-dimensional methods have been devised to increase fiber strength. This includes
