Legislation is driving major changes in the way that certain industries designs and manufactures its products to make them more environmentally friendly and less polluting. In automotive, emissions controls are challenging designers to produce ever lighter vehicles, which has driven them to consider incorporating less dense materials such as polymer composites. In electronics, WEEE Legislation has driven designers to use materials, which are inherently recyclable as well as allowing them design freedom to reduce costs and increase functionality. This has led to a shift towards 3D packaging and the use of thermoplastic encapsulants. RapidPM will develop technology to enable structures comprising fundamentally different material types to be assembled rapidly, consistently and using low cost technology. The basic approach is to use a thermoplastic coating which is deposited onto the surface of one component, usually a metal such as aluminium alloy or copper, and bond this by welding onto the other component which could typically be a thermoplastic or a thermoplastic composite. In this way, designers of structures for the electronics and automotive industries can use the flexibility afforded by advanced thermoplastic processing technologies, the properties of the thermoplastic in use, and the inherent recyclability which thermoplastics bring by remelting. The project will generate results of mechanical test of joints, environmental tests, and techno-economic assessment against conventional adhesive bonding and mechanical fastening techniques.

立法正在推动某些行业设计和制造产品的方式发生重大变化，使其更加环保，污染更少。在汽车领域，排放控制对设计师提出了挑战，要求他们生产更轻的车辆，这促使他们考虑采用密度较低的材料，如聚合物复合材料。在电子产品领域，Wyndham立法促使设计师使用本质上可回收的材料，并允许他们自由设计，以降低成本并增加功能。这导致了向3D包装和使用热塑性塑料的转变。RapidPM将开发技术，使结构包括根本不同的材料类型，以快速，一致地组装和使用低成本技术。基本方法是使用沉积在一个部件（通常是金属，如铝合金或铜）的表面上的热塑性涂层，并通过焊接将其结合到另一个部件上，该另一个部件通常可以是热塑性塑料或热塑性复合材料。通过这种方式，电子和汽车行业的结构设计者可以使用先进的热塑性塑料加工技术提供的灵活性，使用中的热塑性塑料的特性以及热塑性塑料通过重熔带来的固有可回收性。该项目将产生接头的机械测试结果，环境测试，以及与传统粘合剂粘合和机械紧固技术相比的技术经济评估。
