演讲人介绍：
Leif Ickert先生曾在亚琛工业大学学习机械工程专业，主攻汽车工程。自2007始，他加盟亚琛工业大学汽车工程研究院。他已经在以下方面开展若干项目：与轻量设计相关的汽车车身结构设计、新制造技术、经济评估以及汽车概念。目前，他担任先进材料和复合材料主管。
内容简介：
识别新的轻量潜能在汽车行业开发新一代汽车中扮演着关键角色。作出这些努力的主要动力在于希望减少燃料消耗和二氧化碳排放。开发电动车将更加促进轻量设计，以抵消居高不下的电池重量。现在的大型汽车生产中轻量目标是通过密集采用高强度钢材加以实现的。然而，这些轻量潜能已经被挖掘殆尽。进一步通过降低薄板厚度和壁厚来降低重量正在面临来自刚度、噪声、振动和声振粗糙度要求的正面冲突。
最近的趋势表明，轻金属特别是铝在机器罩和门等方面的应用日益增加。工艺（比如，压铸）和材料（具有良好成型性能的高强度合金）方面的进展推动了这种趋势的发展。从中期来看，在多材料车身中使用高强度钢材和其它材料的同时汽车结构中将越来越多地采用轻金属。
纤维增强塑料为轻量设计提供全新的方法。尽管各种疑团还有待一一解答。本演讲将对与下述方面相关的挑战进行简要概述：材料（足够的可用性、材料特性、数值模拟、汽车认证方法）、工艺（周期时间、自动化、联合工艺、质量控制、接合技术、再循环利用）和设计方法（整体设计、生产设计和减少废物）。
再有，在汽车结构中采用纤维增强塑料要求我们对这些材料要有整体上的了解，而不仅仅是做到替代金属结构的这项工作。纤维增强塑料代表着一个具有高度复杂性的材料组别，但与此同时，其为部件和功能整合提供各种机会并可通过目的性设计在轻量方面发挥巨大潜能。关于这一点，要提请注意的是：纤维增强塑料包括增强纤维等各种碳纤维。在一些应用场合中，与较为昂贵的碳纤维相比，玻璃或其它纤维具有优势。
另外，纤维增强塑料在多材料的复合物中具有各种优势，比如，与金属材料相结合，在混合设计中高效利用纤维增强塑料。
科研成果：
纤维增强塑料在轻量设计方面的潜能是众所周知的，其已经被用于若干场合，但是，部件成本高昂时常成为人们争论的焦点。尽管短时间内在材料成本方面不会发生革命性变化，但是，能够实现大规模生产的新型生产技术的发展前景值得期待（一些生产技术已经呈现在人们面前，一些生产技术仍处于研发阶段）。
不过，就电动汽车而言，可以在成本方面挖掘新的潜能，为创新性轻量设计提供新的途径。假如可通过降低汽车重量节省高昂的电池容量，则可从全新的视角对轻量的量度进行评估。众多汽车制造商正在实施各种计划研究“新”材料。然而，与学术界建立紧密的合作关系以满足研究需求是一件很重要的事情。
汽车行业已经通过各种新途径打造轻型、可持续的未来，中国必须成为在这方面的关键合作伙伴之一。
Speaker Introduction:
Dipl.-Ing. Leif Ickert studied mechanical engineering at RWTH Aachen University with the focus on automotive engineering.Since 2007 he is employed at the Institut für Kraftfahrzeuge (ika) RWTH Aachen University. He has worked on several projects concerning the structural design of automotive vehicle bodies with regard to lightweight design, new manufacturing technologies and economic assessment as well as vehicle concepts. He is currently leader for advanced materials and composites.
Abstract of Speech:
The identification of new lightweight potentials plays a key role in the automotive industry during the development of new vehicle generations. These efforts are mainly driven by a desired reduction of fuel consumption and CO2 emissions. The development of electric vehicles will push the trend towards lightweight design even more as high battery weights have to be compensated.Current lightweight goals in large-scale production vehicles are achieved by the intense use of high strength steel. However,these lightweight potentials are already exhausted to a great extent. The weight reduction by means of further sheet or wall thickness reduction is facing a direct conflict with the requirements for stiffness and noise vibration harshness (NVH).
Latest trends show an increasing use of light metals, in particular the use of aluminium in applications such as bonnet and doors. Developments on the process side (e.g. die casting) and the material side (high strength alloys in combination with good formability properties) have pushed this trend. In the mid-term an increasing use of light metals can also be expected in the vehicle structure alongside with high strength steel and other materials in a multi-material body.
Fibre reinforced plastics (FRP) offer completely new approaches in lightweight design. Even though a number of questions have to be answered. The presentation will give a brief overview on the challenges concerning materials (sufficient availability, material characterisation, numeric simulation, automotive qualifycation methods), processing (cycle times, automation, process integration,quality control, joining technology, recycling) and design methods (integral design, design for production, scrap reduction).
Moreover, the implementation of FRP into automotive structures demands the integral understanding of these materials to achieve more than just the substitution of metal structures. FRP stand for a material group with a high complexity, but in the same way for a diversity of opportunities for part and functional integration and a huge lightweight potential by means of purpose design. In this context it will be mentioned, that FRP includes more the carbon fibre as reinforcing fibres.In some applications glass or other fibres can show an advantage in comparison to the rather expensive c-fibre.
Beyond that it will be shown that FRP can display advantages in a multi material composite e.g. in combination with metallic materials aiming at an efficient use of FRP in a hybrid construction.
Lightweight potentials by the use of FRP are well known and have been demonstrated in several applications, but high part costs have always been the crucial argument. New advances in reduction technologies (some already available, some still in development) capable of enabling a large-scale production show a perspective, even though a revolution on the side of the material costs cannot be expected in the near future.
Nevertheless, new cost potentials could be gained in correlation with electric vehicles, offering new approaches for innovative lightweight designs. If expensive battery capacity could be saved through a low vehicle mass, lightweight measures could be assessed from a new point of view. A lot of vehicle manufacturers are currently running development programs to learn about the “new” material. Nevertheless, it is important to have a close cooperation with academia to fulfill the research needs.
The automotive industry is ready to take new routes for a light and sustainable future and China must be one of the key partners in that concern.
