Title (EN) REINFORCING FIBER BUNDLE AND MOLDING MATERIAL
(FR) FAISCEAU DE FIBRES DE RENFORCEMENT ET MATÉRIAU DE MOULAGE
(JA) 強化繊維束および成形材料
Abstract:
(EN) Disclosed is a reinforcing fiber bundle which comprises a propylene resin (A), a propylene resin (B) that contains at least a carboxylic acid salt bonded to the polymer chain, and reinforcing fibers (C), and wherein: the propylene resin (A) contains more than 70% by mass but 100% by mass or less of a component (A-1) that has a weight average molecular weight of 150,000 or more; the amount of the propylene resin (B) relative to 100 parts by mass of the propylene resin (A) is 3-50 parts by mass; and the total content ratio of the propylene resin (A) and the propylene resin (B) is 0.3-5% by mass of the whole reinforcing fiber bundle. This reinforcing fiber bundle has excellent mechanical properties and excellent handling properties. Also disclosed is a molding material which contains this reinforcing fiber bundle and a matrix resin.
(FR) L'invention concerne un faisceau de fibres de renforcement qui comprend une résine de propylène (A), une résine de propylène (B) qui contient au moins un sel d'acide carboxylique lié à la chaîne de polymères et des fibres de renforcement (C) et : la résine de propylène (A) contenant plus de 70 % en masse mais 100 % en masse ou moins d'un constituant (A-1) qui présente un poids pondéral moléculaire moyen de 150.000 ou plus ; la quantité de la résine de propylène (B) par rapport à 100 parties en masse de la résine de propylène (A) étant de 3 à 50 parties en masse ; et le rapport de teneur totale en résine de propylène (A) et en résine de propylène (B) étant de 0,3 à 5 % en masse de la totalité du faisceau de fibres de renforcement. Ce faisceau de fibres de renforcement présente d'excellentes propriétés mécaniques et d'excellentes propriétés de manipulation. L'invention concerne également un matériau de moulage qui contient ce faisceau de fibres de renforcement et une résine de matrice.
(JA) プロピレン系樹脂(A)と、重合体鎖に結合したカルボン酸塩を少なくとも含むプロピレン系樹脂(B)と、強化繊維(C)とを含み、プロピレン系樹脂(A)は重量平均分子量が15万以上の成分(A-1)70質量%を超え100質量%以下を含み、プロピレン系樹脂(A)100質量部に対して、プロピレン系樹脂(B)の量は3~50質量部であり、プロピレン系樹脂(A)とプロピレン系樹脂(B)の合計の含有率は強化繊維束全体の0.3~5質量%である、機械物性および取扱い性に優れた強化繊維束;並びに、この強化繊維束とマトリックス樹脂を含む成形材料が開示される。
