The test method covered by this standard is used to determine the residual compressive strength and compressive strain after impact of multidirectional laminates made of unidirectional or woven fabric prepreg. The test method is intended for dry and conditioned test specimens. It may be applied at ambient as well as low and elevated temperatures.
