Title
(EN) METHOD FOR PRODUCING FIBER-REINFORCED PLASTIC JOINED BODY FROM PREPREG
(FR) PROCÉDÉ DE PRODUCTION D'UN CORPS ASSEMBLÉ EN PLASTIQUE RENFORCÉ PAR DES FIBRES À PARTIR D'UN PRÉIMPRÉGNÉ
(JA) プリプレグから繊維強化プラスチック結合体を製造する方法
Abstract
(EN)
The method for producing a fiber-reinforced plastic joined body from a prepreg comprises heating the prepreg in an atmosphere at above ordinary temperature but lower than the prepreg curing temperature and at a lower pressure than atmospheric pressure, temporarily joining semi-finished products obtained in the heating step with one another or with another component, and holding the temporarily joined semi-finished products at the curing temperature or higher to cure the same.
(FR)
Le présent procédé de production d'un corps assemblé en plastique renforcé par des fibres à partir d'un préimprégné consiste à chauffer le préimprégné dans une atmosphère à une température supérieure à la température ordinaire mais inférieure à la température de durcissement du préimprégné et à une pression inférieure à la pression atmosphérique, à assembler temporairement des produits semi-finis obtenus à l'étape de chauffage l'un avec l'autre, ou avec un autre composant, et à maintenir les produits semi-finis assemblés temporairement à une température supérieure ou égale à la température de durcissement pour les durcir.
(JA)
プリプレグから繊維強化プラスチック結合体を製造する方法は、常温を越えて前記プリプレグの硬化温度未満であり大気圧より減圧された雰囲気において前記プリプレグを加熱し、前記加熱する工程により得られた半製品を互いに、または他の部品と、仮結合し、前記仮結合された半製品を前記硬化温度以上に保持して硬化させる、ことを含む。
