Title (EN) SIZING AGENT FOR REINFORCING FIBERS, AND USE THEREOF
(FR) AGENT D'ENCOLLAGE DE FIBRES DE RENFORCEMENT ET UTILISATION ASSOCIÉE
(JA) 強化繊維用サイジング剤及びその利用
Abstract:
(EN) Provided are: a sizing agent for reinforcing fibers, which can simultaneously impart excellent fiber convergence properties in reinforcing fibers used to reinforce a matrix resin, excellent rubfastness, excellent uniformity of adhesion and excellent adhesive properties with a matrix resin; and a synthetic fiber strand and a fiber-reinforced composite material, which use the sizing agent. This sizing agent for reinforcing fibers contains a polyamide (A), a carbodiimide group-containing compound (B) and water (C). The melt viscosity at 150°C of the polyamide (A) is 100-15,000 mPa·s, and the compound (B) has two or more carbodiimide groups in the molecule. The polyamide (A) is preferably a water-soluble polyamide.
(FR) L'invention concerne : un agent d'encollage de fibres de renforcement, qui peut simultanément conférer d'excellentes propriétés de convergence de fibre dans des fibres de renforcement utilisées pour renforcer une résine de matrice, une excellente résistance au frottement, une excellente uniformité d'adhérence et d'excellentes propriétés adhésives avec une résine de matrice ; et un brin de fibre synthétique et un matériau composite renforcé par des fibres, qui utilisent l'agent d'encollage. Ledit agent d'encollage de fibres de renforcement contient un polyamide (A), un composé contenant un groupe carbodiimide (B) et de l'eau (C). La viscosité à l'état fondu à 150 °C du polyamide (A) est de 100 à 15 000 mPa·s, et le composé (B) a deux groupes carbodiimide ou plus dans la molécule. Le polyamide (A) est de préférence un polyamide soluble dans l'eau.
(JA) マトリックス樹脂を補強する為に用いられる強化繊維に対して、優れた繊維集束性、優れた耐擦過性、優れた均一付着性、及びマトリックス樹脂との優れた接着性を同時に付与できる強化繊維用サイジング剤と、それを用いた合成繊維ストランド及び繊維強化複合材料を提供する。 ポリアミド(A)と、カルボジイミド基含有化合物(B)と、水(C)と、を含む強化繊維用サイジング剤であって、前記ポリアミド(A)の150℃における溶融粘度が100~15000mPa・sであり、前記化合物(B)が分子内にカルボジイミド基を2つ以上有する、強化繊維用サイジング剤。前記ポリアミド(A)が水溶性ポリアミドであると好ましい。
