ABSTRACT:
A method for making a flexible fibrous continuous tape containing 60 to 98 wt % fiber based on the weight of the tape, from multifilament yarn selected from aramid, glass, aromatic polyester, and rigid rod polymer, comprising the steps: a1) spreading the filaments of the yarn to obtain a filament layer having a cross sectional aspect ratio (w/h) of 2 to 2000; and b1) treating the spread filaments with a curable resin, or a liquid thermoplastic resin or wax; or a2) treating the yarn with the curable resin, or the liquid thermoplastic resin or wax; and b2) spreading the filaments of the yarn to obtain a filament layer having a cross sectional aspect ratio (w/h) of 2 to 2000; followed by c) fixating the filaments by curing or solidifying the resin to obtain the tape, wherein steps a1-b1, respectively a2-b2, and c are performed in-line.
