摘要：

The Charpy impact test method has been widely used to investigate impact resistance of fiber reinforced composites because of its simplicity. However, when laminated composites such as CFRPS are to be tested, each specimen may have different thickness without a notch. This may result in incorrect material evaluation for impact resistance. In this paper, an instrumented Charpy impact tester was introduced in order to determine a proper Charpy impact test method for CFRPs and to investigate the effect of the ratio of the support-span length to thickness l/t on impact characteristics for both unidirectional and fabric CFRPs.
