Title:
FIBER-REINFORCED STRAND, METHOD OF MANUFACTURING A FIBER-REINFORCED STRAND
Document Type and Number:
WIPO Patent Application WO/2012/093561
Kind Code:
A1
Abstract:
In the disclosed method of manufacturing a fiber-reinforced strand, a fiber-reinforced strand is manufactured in such a way as to assume a state in which the cross-section thereof approximates a circle as nearly as possible. The method involves passing a reinforced fiber bundle (3) through a resin bath means (7) to create a resin-impregnated reinforced fiber bundle (3) and thereafter imparting a twist to the reinforced fiber bundle (3). When the resin bath means (7) has an impregnation region (21) where the reinforced fiber bundle (3) is impregnated with a thermoplastic resin (5), and a twist-imparting region (22) where a twist can be imparted to the resin-impregnated reinforced fiber bundle (3), twists are imparted over the distance L of the twist-imparting region (22) such that the twisting pitch P, at which twists are imparted to the resin-impregnated reinforced fiber bundle (3), fulfills L/3≥P≥3.15/90×(dtex)1/2.
