Multiaxial Warp Knit (MWK) fabrics have brought together the advantages of textile technology: high deposition rates, unlimited shelf-life, low cost and improvement in damage tolerance. The effect of stitching architectures of such fabrics is reported in this work. Three stitch architectures of carbon MWK, in epoxy matrix, were considered. Damage resistance and tolerance testing were carried out on dry and aged samples along with DMTA, FTIR, Raman Spectroscopic analysis. Investigations showed that during low energy impact high stitch density offered more damage resistance, being directly...
