Title (EN) PREFORMS FOR MOULDING PROCESS AND RESINS THEREFOR
(FR) PREFORMES DESTINEES A UN PROCEDE DE MOULAGE ET RESINES UTILISEES A CETTE FIN
Abstract:
(EN) Binder coated fibres comprising from 80 to 99 % by weight reinforcing fibres and from 1 to 20 % by weight of a preform binder resin, said binder resin being in the form of particles or discrete areas on the surface of the reinforcing fibres, said binder resin comprising: from 40 to 90 % by weight of the binder resin of a thermosetting resin and from 10 to 60 % by weight of the binder resin of a high molecular weight engineering thermoplastic and/or an elastomer selected from vinyl addition polymer, fluororelastomers and polysiloxane elastomers, the engineering thermoplastic/elastomer being dissolved in the thermosetting resin, the binder resin being non-tacky at ambient temperature, having a softening point in the range 50 to 150 °C and being heat curable at a temperature in the range 50 to 200 °C.
(FR) L'invention se rapporte à des fibres recouvertes d'une résine de liaison et contenant de 80 à 99 % en poids de fibres de renforcement et de 1 à 20 % en poids d'une résine de liaison de préforme, ladite résine se présentant sous la forme de particules ou de zones espacées situées à la surface des fibres de renforcement. Cette résine de liaison contient de 40 à 90 % en poids d'une résine thermodurcissable et de 10 à 60 % en poids d'une matière thermoplastique industrielle de poids moléculaire élevé et/ou d'un élastomère sélectionné à partir d'un polymère d'addition vinylique, de fluoroélastomères et d'élastomères polysiloxylanes. La matière thermoplastique industrielle/l'élastomère est dissout dans la résine thermodurcissable. La résine de liaison est non-adhésive à température ambiante, présente un point de ramollissement situé entre 50 et 150 °C et peut être durcie à chaud pour une température située entre 50 et 200 °C.
