内饰件阻燃性能的发展趋势
阻燃法规趋势
● Required more severe spec in Flame retardant regulation
对阻燃剂的规定更加严格。
● Tightening of burning speed requirement in Taiwan, Middle East, and Brazil since 2015
自2015年起,台湾、中东、巴西等地开始加强对燃烧速度的要求。
● Result from ISO17025 certified Test Laboratory is mandatory in Thailand
在泰国,由iso 17025认证的测试实验室产生的结果是强制性的。

Flame Retardant Test (Horizontal method)
阻燃性实验(水平燃烧测试)
● Horizontal method is required for Passenger Vehicles
客车采用水平测试方法

水平测试方法所用烤炉
试样

Set test piece on U-frame of equipment, and burn 15 sec. at edge of test piece A side Measure burning speed from A line to B line
将样品置于设备u型架上,在样品A侧边缘燃烧15秒,测量从A线到B线的燃烧速度

Flame Retardant Test (Vertical method)
阻燃性实验(垂直燃烧测试)
Vertical method is required for Bus
公共汽车采用垂直燃烧测试
Vertical method is 3 ~ 4 times severe than Horizontal method
垂直法比水平法剧烈3 ~ 4倍
电动车对复合材料的需求
Necessity of Lightweight <Technology level>
轻量级的必要性<技术级别>
● Weight reduction by steel structure optimization and AL for Eng. vehicle
采用钢结构和铝制车辆发动机来优化减重
● Multi-material structure is necessary to compensate EV mass increase
多材料结构是补偿电动汽车质量增加的必要手段

Current status of Composite Battery case upper case
复合电池外壳的现状
● Increase composite adoption for Battery Upper Case
增加电池外壳复合材料的采用

Battery Pack: Trend of flame retardant regulation
电池组:阻燃剂相关的法规趋势

Battery Pack: Fire Resistance Test
电池组:抗燃烧性测试
※UN R100,中国法规GB/T31467.3 - 2015记载
● Purpose of regulation
法规制定的目的
・ Confirmation of fire resistance from external fire
从外部火焰确定抗燃烧性
● Test Procedure 实验步骤
・ 70 sec. direct fire exposure to battery pack
电池组直接暴露在火中70秒
・60 sec. indirect fire exposure (with screen) to battery pack
电池组件的间接暴露在火中60秒(有屏幕遮挡)
・3 hours observation after test end
三个小时后观察测试结果
● Criteria : No explosion
合格标准:没有爆炸

Summary
总结
● Required more severe spec in Flame retardant regulation
对于阻燃剂的法规更加严格是必要的
● Multi-material structure with composite is necessary to compensate EV mass increase
为了补偿电动车质量的增加,必须要采用复合材料的多材料结构
● For composite battery pack, fire resistance performance is mandatory for safety
对于复合电池组,为了安全,防火性能是必须的
