Different experimental ways to minimize the preforming defects of multi-layered interlock dry fabric

Abstract : This study presents a strategy to improve the quality of a dry fabric’s preforms. Preforming tests were realized with one and two-layers of interlock carbone fabric at different configurations. Initial results led to preforms with several defects. For one-layer preforming, a new blank holder geometry and an increase of the pressure applied on the fabric allowed to improve the quality of the preforms. On the other hand, for two-layer preforming, the insertion of a mat fabric in the interface of the two preformed layers allowed to decrease the friction and to improve the preforms quality, significantly.
