报告摘要：The successful development of all composite structure aircraft, for example well known Boeing's 787 and Airbus's A350 aircrafts, represents a revolutionary breakthrough in composite material technology. However, it is well recognized that the compressive strength of advanced resin-based composites is much lower than the tensile strength. The higher the fiber strength property, the greater the gap. The low compressive strength of high-performance carbon fiber reinforced polymer (CFRP) composites has been an issue in the companying composites industry for decades. K Niu and R Talreja (2000) proposed a resin controlled yield criterion for the compressive failure of unidirectional fiber composites, which turned out to be in a very simple expression as the rule of mixtures for axial compression. The rule of mixtures is illustrated to show compressive failure of a fiber composite in this presentation.
