Title (EN) METHOD FOR PRODUCING FIBER-REINFORCED PLASTIC
(FR) PROCÉDÉ DE FABRICATION D’UN PLASTIQUE RENFORCÉ DE FIBRES
(JA) 繊維強化プラスチックの製造方法
Abstract:
(EN) Provided is a method for producing a fiber-reinforced plastic having high mechanical properties and high productivity during molding of complex shapes. A method for producing a fiber-reinforced plastic in which a sheet base material A is used, wherein: the sheet base material A is a base material having one or more sheets of notched prepreg a; the notched prepreg a is a prepreg in which a plurality of notches for separating unidirectionally oriented reinforcing fibers are inserted in a prepreg having the reinforcing fibers and a resin; and the method for producing a fiber-reinforced plastic includes a placement step (A) in which a plurality of sheet base materials A are placed in a mold such that each of the sheet base materials A forms an overlapping part that overlaps one or more other sheet base materials A and a non-overlapping part that does not overlap, and a molding step in which the plurality of sheet base materials A are heated and pressurized, the total area of the overlapping parts and the non-overlapping parts being 50-100% relative to the area of the mold surface.
(FR) La présente invention concerne un procédé de fabrication d’un plastique renforcé de fibres ayant des propriétés mécaniques élevées et une productivité élevée durant le moulage de formes complexes. L'invention concerne plus précisément un procédé de fabrication d’un plastique renforcé de fibres dans lequel un matériau de base en feuille (A) est utilisé, selon lequel : le matériau de base en feuille (A) est un matériau de base ayant une ou plusieurs feuilles de préimprégné entaillé (a) ; le préimprégné entaillé (a) est un préimprégné dans lequel une pluralité d’entailles de séparation des fibres de renfort unidirectionnellement orientées sont insérées dans un préimprégné présentant les fibres de renfort et une résine ; et le procédé de production d’un plastique renforcé de fibres comprend une étape de mise en place (A) dans laquelle une pluralité de matériaux de base en feuille (A) sont placés dans un moule de sorte que chacun des matériaux de base en feuille (A) forme une partie chevauchante qui chevauche un ou plusieurs autres matériaux de base en feuille (A) et une partie non chevauchante qui ne chevauche pas, et une étape de moulage dans laquelle la pluralité des matériaux de base en feuille (A) sont chauffés et placés sous pression, la zone totale des parties chevauchantes et des parties non chevauchantes représentant de 50 à 100 % par rapport à la superficie de la surface du moule.
(JA) 複雑形状成形時に高い力学特性と高い生産性を有する繊維強化プラスチックの製造方法を提供する。シート基材Aを用いた繊維強化プラスチックの製造方法であって、 前記シート基材Aは、切込プリプレグaを一枚以上有する基材であり、 前記切込プリプレグaは、一方向に配向した強化繊維と樹脂とを有するプリプレグに対して、強化繊維を分断する複数の切込を挿入したプリプレグであり、 複数のシート基材Aを、それぞれのシート基材Aが他の一枚以上のシート基材Aと重なった重ね部及び重なっていない非重ね部を形成するように、型に配置する配置工程(A)、並びに、複数のシート基材Aを加熱・加圧する成形工程とを含み、前記重ね部と非重ね部の面積の合計を、型表面の面積に対して50~100%とする繊維強化プラスチックの製造方法である。
