 Full text | Abstract: Knitted glass fabrics as a kind of reinforcement have received great attention in the composites industry in recent years. Glass yarns, however, are very difficult to be processed in the knitting process due to their high stiffness, low elongation and high coefficient of friction. In this paper, the knittability of glass ply yarns, which are of different yarn parameters, were investigated by testing their mechanical performance using a self-developed knit simulating apparatus. The experimental results show that damage caused to glass yarn during the knitting process is closely related to yarn parameters. Composition modification, fibre diameter reduction, optimising of sizing formulation and yarn twist introduction can provide glass yarn with a much better performance during severe abrasive interaction. |
