摘要

Impact performance of two-dimensional quasi-isotropic laminates subjected to impact loading with flat-ended impactors has been studied in terms of impact stress, strain rate, and volume fraction of laminae. A simple model was formulated to predict impact stress within an elastic limit as a function of volume fractions of laminae. Individual impact parameters for syntactic foam and fiber-reinforced epoxy were experimentally obtained at impact energy levels of 0.54 and 0.87 joule, and used to predict impact stress of the laminates made of the same materials. A reasonable agreement between predictions and experimental results were found. (C) 2003 Wiley Periodicals, Inc. J Appl Polym Sci 89: 2306-2310, 2003. [References: 10]
