Abstract : Hydrostatic pressure can cause significant changes in the mechanical properties of composite materials. A thorough understanding of these effects is essential for the effective design of composite structures for high-pressure applications. In this report, the literature on the effects of hydrostatic pressure on the mechanical behavior of composite materials is reviewed. This includes a general description of the effects of hydrostatic pressure on unreinforced polymers and a detailed critique of the experimental work that has been done on composite materials. The section on composites is divided into three parts: compressive, tensile, and shear testing. For each type of testing, the test materials and techniques and the physical and quantitative results are discussed. (MM)
