汽车业轻量化还远远不够
杜邦公司的全球汽车技术总监Jeffrey 负责将杜邦众多的先进材料带入汽车业，帮助汽车行业不断开发出安全且富有驾驶乐趣的低排放、高燃效车辆。
在1988年进入杜邦，担任合成化学家。他担任过多项职务，后被提拔到管理层。2006年，加入了中央研究开发/材料科学和工程事业部，他领导的团队专注于开发光伏材料解决方案，用于改善换能效率，降低成本和延长系统寿命。
持有芝加哥大学的化学学士学位和伊利诺斯大学的有机化学博士学位。
和本刊记者Frank Esposito一同探讨了材料市场。
问：轻量化与杜邦材料战略的哪些方面相契合？
：无论对于杜邦还是整个汽车业来说，轻量化仍是一个重要的推力。我们做了一项基准比较调查，对行业内旨在实现轻量化和燃油效率的策略展开调查，在该调查中，只有25%的受访者表示，他们相信他们使用的材能够达到2025年的排放标准目标。成本是最大关卡。要达到规定没问题，但关键在于汽车制造商对消费者的成本转嫁承受力的把握。
问：杜邦通过哪些方式来完善其材料？
：我们不断改善工程聚合物的性能属性，比如高热稳定性、韧性和刚度。客户要求得到更具成本效益的解决方案，因此我们与客户和OEM密切合作以求实现这一切。
有些新型聚合物的加工效率更高。我们已经超越材料本身，通过系统方式让最终用户受益。我们将推出各种新型层压和混合材料，以及添加新型填充物的复合材料，不断推陈出新和改善材料性能。
问：您是否担心在某些应用中存在材料的工程设计过度的情况？
：我们从未听说材料方面有工程设计过度的情况。相反，有些属性方面仍有欠缺，比如增加刚性。
问：杜邦可采取哪些措施来扩大轻量化范围？
：我们在设计方面有很多工作要做，要设法用轻型塑料来取代金属件。我们需要考虑客户需求的范围。我们为[汽车零部件]添加肋架和改良波纹管设计。此外还把重点放在加工速度上。在零部件整合方面，可借鉴OEM是如何把某种材料引入车辆中的。我们可以简化供应链。
问：石油和天然气价格的下跌是否对车用塑料产生影响？
：从长远来看，我们不认为会产生巨大变化。天然气价格下跌可能只是暂时性的。美国汽车排放标准未有改变 。虽然企业购买材料的方式可能会改变，但轻量化仍是主要目标。
问：杜邦在车用塑料方面的现状如何？
：我们已围绕再生来源聚合物实施了多项计划。我们的工业生物科学开发成果也被应用于先进的车用材料中，如Sorona、 Hytrel和长链尼龙。
无论在何种应用领域，[生物塑料]都引起了广泛关注，无论是在热管理系统还是车用Sorona地毯中。[生物塑料的]引擎罩下应用也是一大目标。
客户迫切希望使用生物塑料，但挑战在于要找到合适的应用领域。例如，既要能让地毯呈现极其柔软的质感，同时要比尼龙或聚酯更好地防污渍，易于清理。
近年来，对新材料的总体需求很大。其推动力之一在于监管，另一方面则是对差异化的需求。新技术受到了最终消费者的极大青睐，所以有许多OEM在力求确立其创新地位。
