Patent ID: 8062448

Claim:
A method of making a multiaxial fibre sheet having a longitudinal direction, the method comprising: superposing at least two unidirectional sheets fed in different directions onto a support that moves in a direction of advance parallel to the longitudinal direction of the multiaxial sheet to make, and bonding the superposed sheets together, wherein at least one of the unidirectional sheets is formed by spreading at least one tow of filaments so as to obtain a sheet of substantially uniform thickness, having a width of not less than 5 cm and a weight of not more than 300 g/m 2 , and the at least one unidirectional sheet is fed in a direction transverse to the direction of advance, and successive segments of unidirectional sheet are fed at a selected angle relative to the direction of advance by repeating a sequence comprising: moving the at least one unidirectional sheet above said support parallely to the transverse direction, cutting out a segment from the at least one unidirectional sheet, and depositing the cut off segment on said support or on the multiaxial sheet that is being made to be superposed with at least one other unidirectional sheet, and transverse cohesion is provided to the at least one unidirectional sheet and maintained while the at least one unidirectional sheet is handled prior to being deposited as successive segments.
