Abstract

In this work the effectiveness of the one-dimensional (1D) electrical resistance method at sensing low velocity impact damage in AS4/3501-6 carbon fiber polymer matrix laminated composite plate specimens was studied. A fully instrumented experimental setup for characterization of electrical properties has been developed. Two types of laminates were tested: a 16-ply orthotropic [0/45/-45/90]2s laminate (thickness = 2.25 mm) and a 32-ply orthotropic [0/45/-45/90]4s laminate (thickness = 4.5 mm). Single impact and cumulative damage studies were conducted for both the 16- and 32-ply samples. Before and after each impact, the top surface resistance and the oblique resistance (resistance through the thickness of the specimen at an oblique angle) of the impact region were measured and their effectiveness to sense damage was evaluated.
