The invention discloses a rail train, a train head and a manufacturing process of the train head. The rail train comprises an inner skin and an outer skin, the reinforcing beam is located between the inner skin and the outer skin, and the reinforcing beam and the outer skin are cured and formed; the foam sandwich is filled between the inner skin and the outer skin, and the reinforcing beams are embedded in the foam sandwich; the inner skin, the outer skin and the reinforcing beams are all integrally formed through mold pressing of carbon fiber composite materials. Due to the fact that the carbon fiber composite material is small in specific gravity, excellent in mechanical property such as specific strength, specific stiffness and tensile strength and light in foam weight, the mechanical property of the product structure can be met while the weight of the product is reduced, and therefore the train head solidified through the material can achieve the light weight and solve the problem caused by deformation at the same time. Due to the fact that the reinforcing beam and the outer skin are formed in the curing mode, the outer skin and the reinforcing beam can be connected more firmly, the problem that the assembling relation is improper due to deformation generated when the reinforcing beam is independently cured is solved, the production period is shortened, and cost is reduced.

    本发明公开了一种轨道列车及列车车头和列车车头的制造工艺,其包括:内蒙皮和外蒙皮;位于内蒙皮与外蒙皮之间的加强梁,加强梁与外蒙皮固化成型;填充在内蒙皮与外蒙皮之间的泡沫夹芯,加强梁内嵌于泡沫夹芯;内蒙皮、外蒙皮和加强梁均由碳纤维复合材料模压一体成型。由于碳纤维复合材料的比重较小,比强度、比刚度、抗拉伸强度等力学性能优异,泡沫重量较轻,在使产品减重的同时,可满足产品结构的力学性能,因此,采用上述材料固化的列车车头可实现轻量化的同时降低形变带来的问题。由于加强梁与外蒙皮固化成型,可使外蒙皮与加强梁连接的更为紧固,解决了加强梁单独固化时产生的形变而导致装配关系不当的问题,还缩短了生产周期,降低了成本。
