Document Type and Number:
Japanese Patent JP7123047
Kind Code:
B2
Abstract:
A sheath-core composite yarn 1 for fiber-reinforced resins, which comprises a core yarn 2 and covering yarns 3, 4, and wherein: the core yarn is a superfiber yarn that has a strength of 14 cN/decitex or more and an elastic modulus of 300 cN/decitex or more; each of the covering yarns 3, 4 is at least one yarn selected from among a carbon fiber yarn, a glass fiber yarn, an aramid fiber yarn and a high-strength polyethylene fiber yarn; and the covering yarns 3, 4 are composed of at least two yarns which have different winding directions and cover the circumference of the core yarn 1. A fiber-reinforced resin according to the present invention is obtained by integrally molding the sheath-core composite yarn 1 with a matrix resin or by integrally molding a fiber structure that contains the sheath-core composite yarn 1 with a matrix resin. Consequently, the present invention provides: a sheath-core composite yarn for fiber-reinforced resins, which has high impact energy absorption properties; and a fiber-reinforced resin which uses this sheath-core composite yarn for fiber-reinforced resins.
