rovings of structural composites containing carbon fibers and having a polymer matrix known for example under the reference as4 pekk fc of u00bc inch were draped side by side over the various nonwovens the dimensions of the draped plies are therefore 305 mm wide by 1100 mm long the dimensions of the nonwovens were 500 mm u00d7 1200 mm the clamping of the nonwovens was provided by adhesive tape at the periphery the various configurations tested and the results obtained are presented in the table below that a peek nonwoven or a peek pei nonwoven comprising from 60 to 70 of peek constitutes a material that is adequate for the application that needlepunching and in particular needlepunching of 50 to 130 strokes minute and preferably of 110 strokes minute with a tolerance of 5 to 10 gives a greater strength to the nonwoven that hydroentangling of the order of 40 to 80 bar and more specifically of 60 bar with a tolerance of 5 to 10 is advantageous the drape forming tests have brought to light the importance of clamping the nonwovens specifically depending on the positioning of the clamping the accuracy of the drape forming varies it was therefore necessary to develop effective clamping solutions several types of clamping can be used mechanical clamping using screwed or.
