Abstract

L'invention concerne un procédé et un dispositif de préparation d'un fil de fibre pour le soudage par friction-malaxage, ainsi qu'un procédé de soudage pour un fil de fibre. Le procédé de préparation comprend les étapes suivantes : S1, étalement d'un matériau fibreux en forme de faisceau et pré-imprégnation dans un adhésif de mise en forme pour former une bande fibreuse unidirectionnelle à couche mince, et fusion et plastification d'un polymère thermoplastique puis application de celui-ci sur la bande fibreuse unidirectionnelle à couche mince pour former une bande de revêtement de fibres ; S2, enroulement axial de la bande de revêtement de fibres pour former un fil préimprégné unidirectionnel multicouche en fibre/polymère ayant une section circulaire ; et S3, fendage du fil préimprégné unidirectionnel multicouche en fibre/polymère, en le maintenant dans un état semi-connecté, et en effectuant un traitement de fusion à chaud et un refroidissement pour obtenir un fil de fibre qui est fusionné après le fendage. Le fil de fibre de la présente invention peut être distribué uniformément et de manière omnidirectionnelle sur une pièce à souder pendant le soudage, ce qui améliore considérablement la résistance d'un cordon de soudure ; les fibres fendues peuvent être entraînées par une tête d'agitation tournant à grande vitesse, de manière à être distribuées de manière omnidirectionnelle à 360 degrés, et le cordon de soudure à tous les angles peut être renforcé par les fibres, ce qui permet d'éviter l'anisotropie des propriétés mécaniques, qui peut être causée par le renforcement de la fibre, au niveau du cordon de soudure.
