Abstract
(EN) Provided is a method for cutting a high-strength fiber sheet in which a high-strength fiber sheet comprising a high-strength fiber for forming fiber-reinforced plastics is cut by means of sprayed abrasive grains. In this method for cutting a high-strength fiber sheet, a nozzle is moved so as to trace the outline, having a prescribed shape, of a sheet to be produced while spraying compressed air containing abrasive grains from the nozzle towards the high-strength fiber sheet, whereby the high-strength fiber sheet placed on a net-like base is cut to a prescribed shape.
(FR) L'invention concerne un procédé de découpe d'une feuille de fibres à haute résistance dans lequel une feuille de fibres à haute résistance, comprenant une fibre à haute résistance pour former des matières plastiques renforcées par des fibres, est découpée au moyen de grains abrasifs pulvérisés. Dans ce procédé de découpe d'une feuille de fibres à haute résistance, une buse est déplacée de façon à tracer le contour, ayant une forme prescrite, d'une feuille à produire tout en pulvérisant de l'air comprimé contenant des grains abrasifs à partir de la buse vers la feuille de fibres à haute résistance, moyennant quoi la feuille de fibres à haute résistance placée sur une base de type filet est découpée dans une forme prescrite.
(JA) 繊維強化プラスチック形成用の高強度繊維からなる高強度繊維シートを噴射した砥粒により切断する高強度繊維シートの切断方法を提供する。本高強度繊維シートの切断方法は、ノズルから砥粒を含む圧縮空気を前記高強度繊維シートに向けて噴射しながら、作製するシートの所定形状の輪郭をなぞるように前記ノズルを移動させることにより、網状の基台に載置された前記高強度繊維シートを所定の形状に切断する。
