Patent ID: 8168022

Claim:
Process for producing a laminate being built of at least two monolayers of polymeric tapes, the polymeric tapes having a tensile strength of at least 200 MPa, the polymeric tapes having a sheath/core structure and the sheath material is applied to the core material in a later step with a doctor blade, by spraying, powder coating or leading the tapes through a polymer solution, dispersion, said process comprises the steps of forming a first monolayer of polymeric tapes by pre-tensioning the polymeric tapes and subsequently positioning the polymeric tapes under tension in a unidirectional, parallel manner, forming at least a second monolayer over the first monolayer in the same manner the first monolayer is formed, thereby stacking the at least two monolayers of polymeric tapes in such a way that the polymeric tapes in the first monolayer are oriented in the same direction as the polymeric tapes in the second monolayer and that the polymeric tapes of each monolayer are offset to the tapes of the adjoining monolayer above or below that monolayer consolidating the thus stacked monolayers of polymeric tapes to obtain a laminate.
