composite/compounding material in upper application, force large can separation is type: composite/compounding material non force parts and composite/compounding material force parts. its in composite/compounding material non force parts also can separation is force parts （如车身, sheet/plate and base/seat and other non force parts ） and parts （洗漱间, and water tank and other 辅助构 parts ）, composite/compounding material force parts main/primary is 指列车车体, machine and toward 架构架 and other large type force parts, it is composite/compounding material 取代传统材 material, achieve light amount key/critical.

1, composite/compounding material in 列车辅助 parts and generally force parts upper application

Japan new dry use high speed in, glass fiber reinforcement material （GFRP） composite/compounding material main/primary use in inner frame, 洗漱间, 厕, small 便池, water tank, 集便箱, front cover/cap sheet/plate, di 层客车两端车顶 sheet/plate, 空调风道 天花 sheet/plate and 餐车空调 cover/cap sheet/plate 侧天花 sheet/plate and other 部位. is decrease/reduce electrical 弓周围 空 gas force 噪声, in upper 安装 受 electrical 弓罩也 is using/adopting GFRP材 material manufacturing. 200系东北, upper new dry 线客车 using/adopting 蜂窝夹层材 material manufacturing sheet/plate, in 间间壁门 and other.

同样, France TGV high speed 列车也 a large amount of using/adopting fiber reinforcement plastics （FRP） manufacturing sheet/plate, sheet/plate, frame 架, base/seat and and other. using/adopting FRP manufacturing this parts, remove weight light outer, also tool has easy design, decrease light repair as 业, and can using/adopting overall molding reduce cost and other advantages. in addition, use 玻璃钢 sheet/plate, overall 卫生间 in outer already relatively and, solution issues, also to decrease light weight 目.

Italy ETR500 type high speed upper, has internal structure 边墙, sheet/plate and 行李舱都 use high ratio rigid degree composite/compounding material sheet/plate ——两层Tedlar poly fluorine ethylene plastics thin in has Nomex蜂窝芯材 glass fiber (GF) aldehyde laminate; Europe 之星列车也 use aldehyde sheet/plate its internal structural parts.

UK iron 路部门 through experiment/testing rear 发现, selection fiber reinforcement composite/compounding material electrical 弓头, its property can non 常令人满意. in recent years, composite/compounding material also by use impact resistant parts, and very good experiment/testing 结果.

2, composite/compounding material manufacturing 列车主承 force parts

currently, fiber reinforcement composite/compounding material in structural parts upper application 也越 越 more, its technology already basic 接近实际 application. 列车司 machine 室, and toward 架构架 and other as is large type force parts, in structure weight in has relatively large ratio/proportion, 车体部 separation heavy 占车辆自 heavy 15%~35%, toward 架占车辆自 heavy 25%~35%. therefore, this separation is application new material main/primary research field/area.

（1） high speed 列车 司 machine 室. its front outer need made formed 鼻状形, need light amount 化, also need resistant impact, in 此FRP obtain application. UK 城间 125 type machine machine front is use lamination FRP sheet/plate polyurethane ester foam formed structure, ratio made parts light 30%~35%, can resistant 0.9Kg heavy block 以300Km/h speed degree impact; Italy ETR500 high speed force 车头部 using/adopting Kevlar fiber and ring oxygen resin pressure molding, its rigid property and impact resistant property good, most high speed degree 达300Km/h.

（2） composite/compounding material 车顶. composite/compounding material in cover/cap upper application can reduce heavy 心, increase 车体运行 stability property. Japan iron comprehensive technology research and Japan iron company combined as, use carbon fiber reinforced plastics （CFRP） made formed high speed 列车车顶, 该CFRP车顶 through viscous and aluminum alloy frame versus 连, rear again through welding and upper aluminum alloy 侧壁连 in 一起. experiment/testing table/sheet 明, using/adopting this type of 车顶 车体 tool has relatively high gas strong/high degree and relatively low heavy 心, but also 每节车厢 decrease light 约300~500Kg

（3） composite/compounding material 车体. 车体 按 process different separation is types:

1, will thick is 2.1mm曲面 sheet/plate and made formed 一体, will molding CFRP outer sheet/plate in aluminum alloy frame upper, made long 6000mm, wide 3300mm, high 3290mm, weight is 680Kg.

2, hot pressure molding made formed long 1000mm, wide 3320mm high 3300mm semi 圆形车体, rear versus in 一起, relatively aluminum alloy weight decrease light 30%. but also aldehyde 基CFRP relatively aluminum alloy has good high temperature resistance property can, aluminum alloy in 400℃ and 40MPa force lower generate large deformation, aldehyde 基CFRP in 500℃ and 130MPa force deformation very small.

（4） composite/compounding material toward 架. machine 车车辆 转 toward is 支承车体, ensure 列车平稳运行 important parts, its is for strong/high degree and fatigue resistance can requirements especially high large type 承载构 parts, Germany AEG and MBB company in research technology 部 支持 lower, made world upper 第一台 composite/compounding material 构架 转 toward 架, Model/Grade is HLD-E, design speed degree 200Km/h. Germany rear, Japan made formed 功CFRP转 toward 架构架, 构架自 heavy is 0.3t, ratio 普通钢 made decrease light 70%, 该构架测梁 is CFRP lamination material structure, sheet/plate thick 16.4mm, using/adopting molding, most high design speed degree 160Km/h.
