Abstract:
1. A method of manufacturing a laminate of unidirectionally arranged polymeric tapes of the core-sheath type, in which the core material has a higher melting temperature than the sheath material, the method comprising: pretensioning the polymeric tapes, and positioning the polymeric tapes and consolidating the polymeric tapes to obtain the laminate, wherein the positioning is carried out in two, three, four or more planes, the polymeric tapes are arranged in each plane in a parallel, side-by-side relationship in a first direction, the polymeric tapes of each plane are offset in a second direction relative to the polymeric tapes in an adjacent plane, the second direction being substantially perpendicular to the first direction, and the polymeric tapes of the laminate are unidirectionally arranged in a single direction in all of the two, three, four or more planes.
