Abstract
Although laminated composites are characterized as having high specific strength, stiffness, corrosion resistance, and have been widely used in load bearing structures, they are vulnerable to low velocity impact damage. Under a low velocity impact, various types of damages such as delamination, matrix cracking, fiber/matrix interfacial debonding, and even fiber fracture occur, significantly reducing the residual load carrying capacity and service lifetime. This article first presents the low velocity impact test procedure on laminated composite, followed by understanding and interpretation of test results, and evaluating the residual strength. Thereafter, the effect of environmental attacks on the low velocity impact response and residual strength were addressed. Presented also here are two analytical models to estimate the compression after impact (CAI) strength, and tension after impact (TAI) strength. Finally, some future perspectives on this research direction are discussed.
