This proposal intends to produce affordable lightweight smart cosmetic automotive panels by combining high strength alloys with shape memory or impact responsive polymers. The objective will be to engineer hybrid panels with high structural integrity and dent resistance that are at least 30% lighter than their monolithic steel counterparts whilst imparting shape memory and deformation rate dependant properties. The intention is to produce a panel with a formed metal 'A' class surface backed with a polymer inner layer. The polymer backing layer will enable the use of significantly thinner metal sheet thus providing significant weight saving. The hybrid panels will be produced using standard polymer injection moulding technology with the metal sheet being formed into the tool by the pressure of the injected polymer (cf. sheet hydroforming) with the polymer being moulded to the back of the metal substrate using micro scale mechanical interlocking. Take up of the technology would have a significant environmental impact by reducing tail pipe emissions and there is significant potential for improved pedestrian safety as a result of improved impact performance of components such as the car bonnet. If this technology was adopted on a single component (i.e. bonnet) with 250k units a year this would save in the order of 1.5 million kg of CO2 per annum. Additionally, the novel manufacturing techniques developed in this project will be a key enabler in the delivery of new product concepts.

该提案旨在通过将高强度合金与形状记忆或冲击响应聚合物相结合来生产负担得起的轻质智能化妆品汽车面板。目标是设计具有高结构完整性和抗凹陷性的混合板，其重量比整体钢板轻至少30%，同时赋予形状记忆和变形率相关特性。本发明的目的是生产具有成形金属“A”级表面的面板，所述成形金属“A”级表面背衬聚合物内层。聚合物背衬层将使得能够使用显著更薄的金属板，从而提供显著的重量减轻。混合面板将使用标准聚合物注射成型技术生产，其中金属板通过注射聚合物的压力形成为工具（参见图1）。片材液压成形），使用微尺度机械联锁将聚合物模制到金属基底的背面。采用该技术将通过减少尾气排放对环境产生重大影响，并且由于汽车发动机罩等部件的冲击性能得到改善，因此行人安全性有很大的改善潜力。如果在一个单一部件（即发动机罩）上采用这项技术，每年可节省25万台，每年可节省150万公斤二氧化碳。此外，该项目开发的新型制造技术将成为交付新产品概念的关键推动因素。
