Ribbons of unidirectional fiber-reinforced plastics material are prepared by laying the unidirectional fibers in parallel strips, alternating with strips of another material, onto a plastics material which is on a backing sheet, applying a second backing sheet to the upper surface, which sheet may also be coated with plastics material, applying heat and pressure, and removing one sheet of release material together with the said alternating strips of another material. |
