Article掺加纤维
在原始设备制造商的努力下，复合材料的使用变得更加广泛，数量更多，从而减轻汽车重量今年早些时候，宝马公司宣布，要在新一代7系列豪华轿车的底盘上，广泛利用碳纤维增强塑料（CFRP）。新车型的重量达到130公斤，比原来的车型更轻，同时在乘客舒适度和安全设备上还有提高。除了能够降低能源消耗和二氧化碳排放，还能降低汽车的惯性重心，并提高操作性能。据SGL集团（宝马CFRP项目主要合作商）首席执行官Jürgen Köhler称，“在BMW7系列上使用碳纤维产品，是碳材料在汽车业里大范围系列应用的里程碑。”混合材料方案车辆是在混合材料“碳芯”汽车结构的基础上制造的。在乘用车单位上，比如中立柱的结构因素上使用CFRP，会提高乘用车的总强度和抗扭弯。因此，乘用车钢板因素的配置是可以调整的，可以明显降低车身重量。CFRP还应用在车辆混合顶棚构架上。碳纤维的应用将由SGL Automotive Carbon Fiber公司开发（SGL-ACF）— 是BMW和SGL集团的合资公司 — 地点是在华盛顿州Moses Lake工厂。工厂在过去几年内的生产力稳步提高。初加工品是这些纤维利用全自动纺织生产工艺制造而成。然后，初加工品将直接送到宝马集团，并及工程CFRP零部件。CFRP is used in the hybrid roof frame of the new BMW 7 SeriesSGL集团在德国Wackersdorf工厂也提供碳纤维面料，以及回收材料。集团与BMW集团一同开发，将这些回收碳纤维产品用于C-柱和保护罩分割物上。宝马公司称，制造i3和i8车型上使用的CFRP密集材料过程的经验 — 以及相关基础设施 — 是结果如此成功的关键。新款BMW7系列使用了大量的额碳纤维，成为汽车业使用第二多的系列CFRP生产项目，仅次于i系列车型。设计，生产和装配CFRP材料的硬度和轻度，使其成为生产汽车结构组件的理想材料。但是广泛使用需要在零部件的设计，生产和装配上进行全新的改变 — 这对汽车制造商来说是个极大的投资。2010年宣布出售Lamborghini的Sesto Elemento，这是扩大使用CFRP最激动人心的案例。Sesto Elemento的562bhp V10是在Gallardo的基础上，用CFRP结构制造。999公斤的汽车能达到100公里/小时，在2.5秒中内就能达到300公里/小时的速度。为了把这种性能发挥的更高程度，Sesto Elemento的生产使Lamborghini的工程师们有机会测试各种技术，应用于今后CFRP零部件的制造商。公司在CFRP技术应用于汽车上历史很长。2001年到2010年，在Murciélago的生产中大约使用了31%的碳纤维增强环氧预浸料。这些材料继而应用于所有外部车体板材，以及内部结构零部件上，最后接合到钢材空间构架上。成本与数量在制造这个汽车的过程中，Lamborghini公司强调，为这些结构铺上CFRP板层，以及常常的高压热加工所产生的高成本。但是公司认为这个工艺适合Murciélago，每年的生产率大概会达到400辆。The Alpha Romeo 4C weighs 895kg and features extensive aluminium and low-density sheet-moulding compoundMurciélago的后续产品Aventador于2011年3月在Geneva车展中亮相，全复合材料构架设计上含有50%的碳纤维。这个设计极大提高了扭转刚度，比Murciélago在碰撞方面显示出更佳的性能。Aventador的CFRP组件每年的产量大约是800个，大部分是利用液体树脂工艺制造，比如真空辅助树脂传递模塑（VaRTM），以及树脂传递模塑（RTM）上。Lamborghini公司认为这些技术在这些数量上是搞笑的，但对更高数量的生产来说，需要开发新的技术。锻造复合材料Lamborghini采用的革新技术当时还有所谓了锻造复合材料，在汽车结构和悬挂摆臂上使用。这是与高尔夫俱乐部制造商Callaway一同合作开发，不连续的纤维增强材料适用于高产量CFRP零部件的生产。锻造复合材料是在碳纤维增强模压塑料板材（CFSMC）的基础上而成，有Quantum Composites公司提供。该材料是由25.4mm长的碳纤维短麻屑（占材料重量的53%）构成，随意分布在两层乙烯基酯树脂中间的衬垫上。这些材料经过滚筒压缩称板材形状，再卷起来，成为标准预浸材料。这个材料用于配对金属工具热压工艺中的压塑法。它能承受大约132-160摄氏度，6.9-10.3MPa的压力，加工时间在3至5分钟。Lamborghini公司称，这种材料能大幅度降低生产循环时间，以及复杂的三维零部件的需要（这在持续的碳叠层组合材料中不典型）。公司利用锻造复合材料，降低了Sesto Elemento悬架控制手臂重量，与铝材质大约轻27%。该材料出现在2010年版Lamborghini Gallardo LP570-4 Superleggera上。此外，这些零部件的生产只需要6分钟。自开发Sesto ...
