Abstract : This paper provides a review of the state-of-the-art of advanced composite materials compression test methods. The problem of evaluating the compression properties for advanced composite materials is addressed by surveying the different test methods that are in use. Compression test methods are categorized in four groups according to method of load application. Each group was evaluated according to test specimen configuration, loading fixture and/or testing apparatus, data acquisition, and data interpretation. The results of the evaluation of the state-of-the-art of advanced composite materials compression test methods are: 1) There is no current compression test method that is universally accepted throughout the composite testing community, and 2) The two contenders for best compression methods are: a) The uniaxially wedge action friction grips loaded coupon IITRI test method, and b) The honeycomb core sandwich beam in four-point bending. This paper provides recommendations of what actions need to be taken in order to adapt a compression test method to be universally acceptable to the composite testing community. (Author)
