REINFORCED WOVEN MATERIAL AND METHOD AND APPARATUS FOR MANUFACTURING THE SAME

摘要

This invention provides a method and an apparatus for manufacturing a reinforcing woven fabric by weaving flat and substantially nontwisted multifilaments of reinforcing fiber having a binding property of 400 - 800 mm in hook drop value as warps and wefts. The methods includes the steps of:
(a) a weaving step for weaving the woven fabric with warps (Twr) and a weft (Twf);
(b) a warp supplying step for supplying the warps (Twr) to the weaving step;
(c) a weft supplying step for supplying the weft (Twf) to the weaving step; and
(d) a taking-up step for taking up the woven fabric woven from the weaving step. Example methods may include the step of opening and widening the warps (Twr) prior to the weaving step and/or opening and widening each of the warps (Twr) and/or wefts (Twf) of the woven fabric. A reinforcing woven fabric having a small thickness and an extremely high covering factor and capable of indicating a high strength can be obtained at a low cost as a substrate for reinforcing composite materials.
