<p>PCT No. PCT/FI89/00020 Sec. 371 Date Jul. 31, 1990 Sec. 102(e) Date Jul. 31, 1990 PCT Filed Feb. 9, 1989 PCT Pub. No. WO89/07673 PCT Pub. Date Aug. 24, 1989.A method for the manufacture of an oriented thread structure for lamination and/or protective purposes is disclosed in which preferably glass, carbon, aramide, borax or ceramic reinforcing threads (1), in general are bound to form an oriented thread mat. The mat can be laminated inside a resin or other binder to form a strong shell structure, in which the strength of the shell is principally based on the strength of the above-mentioned reinforcing threads (1). The laminable thread structure can be easily formed on the surface of a mold and avoids air-bubbles in the laminate. The reinforcing threads (1) are bound to a basic knitted structure consisting of one-sided loops (2) by loops (3, 4) running transversely in the opposite direction.</p> |
