 一, electrical is automotive future market trend

1.国家 policy make

2014 year 5 month 7 day, 工信部 published 《兰亍 add strong/high use enterprise 平均燃 material consumption tube/pipe notice (征求意见稿)》, its in is to 2015 year production use 车平均燃 material consumption amount need drop 至6.9L/100Km and 2020 year 进一步 drop 至5.0L/100Km target/goal, for 不达标 enterprise 提出 惩罚 measures. pressure 倒逼车企寻求 technology type.  

图1: 2010 year world 各国 油 consumption

一直以, 我国乘 use in improves product consumption 方面步伐 relatively slow. from 2006 year to 2012 year, 平均每 year consumption reduce 1.3%. currently, inner use 车 平均油 consumption is 7.38 rise /100公里. 79家 Domestic use enterprise in, has 22家未 can 达标. need to 2015/2020 year 平均油 consumption large 限,根本出路 is new can 源, new material di 轮驱劢!

2. automotive industry trend

Europe electric vehicles will new market 20%, method will achieve can automotive output/production volume 200万辆 target/goal. requirements to 2020 year, new can automotive production can force will 达200万辆, 累计产销 amount ultra- 500辆. “ China manufacturing 2025” will “ energy saving and new can automotive ”列入十 large field/area 之一.  

二, decrease heavy is currently electrical solution main/primary 手段

research table/sheet 明, 约75% 油 consumption and quality has 关, reduce automotive quality, can has reduce consumption and 排放. currently, a large amount of research table/sheet 明, automotive quality decline 10%, consumption decline 6-8%, reduce 4%.

图2: 车 heavy and speed material efficiency 关系

图3: pure electrical 动车整车 quality and can force 关系

table/sheet 1: pure electrical 动车整车 quality and can force 关系

由图2 and 3 and table/sheet 1 can obvious 看出, automotive weight low material efficiency high, from make automotive can force large large improves. therefore, automotive light amount is automotive energy saving and environmental protection, improve/increase can force most has measures 之一.

三, carbon fiber reinforced composite/compounding material is currently solution decrease heavy most good methods

1. various material decrease heavy can force

lower 面, 我们 看看 various material decrease heavy 情况: consumption 钢材400kg is standards, high strength 钢材则 need 320kg, aluminum alloy 240kg, alloy 220kg, composite/compounding material 160kg, decrease heavy force separation is: 10%—20%, 40%, 50%以 and composite/compounding material 60%.

2. various material quality comparison

table/sheet 2 various material quality comparison

3. carbon fiber reinforced composite/compounding material in automotive decrease heavy upper application 实例

leading future 宝马 carbon fiber amount electric vehicles , full carbon fiber 承载式车身总 heavy has 112.2公斤. 号称“宝马 has history technology most 先进 车 type ” 宝马i系 will again leading automotive development 潮流. this 车 4门两 cover/cap is 复材（ outer sheet/plate - engineering plastics, inner add strong/high sheet/plate -玱纤戒 carbon reinforcement ）材 material made formed. forecast in the future in CFRP（ carbon fiber reinforced composite/compounding material ） application 方面会继续领先, 宝马以 outer Europe large automotive 厂商也 will in year 2万～5万辆 production amount upper using/adopting CFRP.

summary:

政府严格 车辆油 consumption standards and oxidation carbon regulations, is new can automotive selection CFRP important 推手. USA is 例, 2017 至2025 year USA new use 车 燃 material efficiency requirements to 4.32 rise / 100 公里, ratio currently water 平几乎 improve/increase 一倍. 据估算, type use decrease heavy 245kg can to target/goal. in 同样续航里程 conditions lower, electric vehicles weight ratio automotive need ultra- 200~300 kg more more.

therefore is ensure electrical automotive has relatively good 续航里程 and can cost, electrical automotive weight must decrease heavy 50% above. in has light amount material in, CFRP is can will 钢质零部 parts decrease heavy 50~60%, can provide and other strong/high degree 先迚材 material. therefore 说, GFRP is future development electric vehicles ratio selection.
