Composite sleeper and preparation method and mold thereof
The invention relates to the technical field of rail transit composite materials, in particular to a composite sleeper and a preparation method and mold thereof. In order to solve the problems that a composite sleeper is low in strength and too large in linear expansion coefficient, the composite sleeper is designed, a base material of the composite sleeper is a short basalt fiber reinforced regenerated plastic polymer, and a long basalt fiber layer is arranged at the position close to each of the upper surface and the lower surface of the sleeper. The strength of the sleeper can be improved, and the linear expansion coefficient of the sleeper can be reduced.
本发明涉及轨道交通复合材料技术领域，具体涉及一种复合轨枕及其制备方法与模具。为了解决复合轨枕强度低、线膨胀系数过大的问题，本发明设计一种复合轨枕，所述复合轨枕基体材料为短玄武岩纤维增强的再生塑料聚合物，在靠近轨枕上下表面处各设有一层长玄武岩纤维层。既能提高轨枕强度，又能降低轨枕的线膨胀系数。
