次地板组件和轨道车辆的地板组件
摘要：
本发明提供了一种次地板组件和轨道车辆的地板组件，次地板组件包括相互连接的上板材和下板材，其中上板材和下板材中至少一个为碳纤维材料制成，上板材和下板材之间形成隔音腔。本发明的次地板组件采用碳纤维材料代替了至少一部分的钢材料，从而在保持强度的情况下，减轻了次地板组件的重量，进而实现了车体减重的效果。
摘要（英）：

The invention provides a sub-floor component and a rail vehicle floor component. The sub-floor component comprises an upper sheet material and a lower sheet material which are connected, wherein at least one of the upper sheet material and the lower sheet material is made of carbon fiber material; a sound insulation chamber is formed between the upper sheet material and the lower sheet material. According to the invention, the sub-floor component is made of carbon fiber material instead of at least part of steel material so that the intensity is maintained and the weight of the sub-floor component is reduced and the weight of the vehicle body is reduced.
