Machine for producing multiaxial fibrous webs |
| 摘要 |
A plurality of unidirectional sheets ( 30 a, 30 b, 30 c) are superposed in different directions and they are bonded together. At least one of the unidirectional sheets is made by spreading a tow so as to obtain uniform thickness, width not less than 5 cm, and a weight of no more than 300 g/m<SUP>2</SUP>, cohesion being imparted to the sheet so as to enable it to be handled prior to being superposed with other sheets. Advantageously, the unidirectional sheets are made of carbon fibers and are obtained by spreading out large tows.
