Résumé : |
One of the major trends in composite manufacturing in recent years has been the development of dry textile preforms that build up the final fibre geometry and structure. The production of such preforms is based, for example, on the sewing, cutting and assembling of flat textiles. In the past, the sewing yarn itself has been an important limitation of this production technique. For this reason, a pure carbon-fibre sewing yarn has been developed that combines excellent processing behaviour and mechanical performance with a reasonable compromise between price, performance and availability. |
