**Abstract**
 The results are discussed of experimental investigations, carried out to understand the response of stitched and unstitched S2-glass/SC epoxy composites to high strain rate compression loading, using a Split Hopkinson Pressure Bar set-up. Fifteen layers of plain weave S2-glass fabric were used to fabricate stitched and unstitched laminates with a low viscosity RTV SC-15 epoxy resin system. A 3-cord Kevlar thread was used for the stitching. Four different types of samples were considered, with sample configurations designated according to the location of the stitch line with reference to the loading direction. Dynamic and static responses of the laminate under compression were compared, and failure modes were studied using optical microscopy. Results showed that under higher strain rates loading, the stitched laminates exhibited a confining effect, and that overall, stitched laminates proved to provide increased damage resistance. 23 refs.
