Abstract
(EN)
A mutually-embedded phenolic resin composite sleeper, comprising: an embedded sleeper body made of a foamed phenolic resin, the sleeper body being internally provided with a uniform or pre-designed non-uniform unidirectional fiber layer on the cross section. Two portions of the sleeper body which form a mutually-embedded structure are bonded together by an adhesive to form the composite sleeper. The mutually-embedded structure is one of a right-angled trapezoid, a trapezoid, and a triangle, preferably the right-angled trapezoid. The composite sleeper uses an embedding technology, and improves a foaming process and a fiber arrangement mode, thereby increasing the lateral strength of the sleeper by more than 50%, and reducing the noise level of the sleeper; and the mechanical strength of the sleeper is effectively improved and the life of the sleeper is prolonged.

La présente invention concerne une traverse composite en résine phénolique à incorporation mutuelle, comprenant : un corps de traverse incorporé constitué d'une résine phénolique moussée, le corps de traverse étant pourvu à l'intérieur d'une couche de fibre unidirectionnelle uniforme ou non uniforme sur la section transversale. Deux parties du corps de traverse qui forment une structure mutuellement incorporée sont liées ensemble par un adhésif pour former la traverse composite. La structure à incorporation mutuelle est un trapèze à angle droit, un trapèze ou un triangle, de préférence un trapèze à angle droit. La traverse composite utilise une technologie d'incorporation, et améliore un processus de moussage et un mode d'agencement de fibres, ce qui permet d'augmenter la résistance latérale de la traverse de plus de 50 % et de réduire le niveau de bruit de la traverse ; et la résistance mécanique de la traverse est efficacement améliorée et la durée de vie de la traverse est prolongée.
