There is an increasing demand for high performance materials many of which are incompatible with conventional manufacturing processes due to their sensitivity with heat and abrasion (e.g. carbon fibre reinforced polymer (CFRP), polymers, thin films, semiconductor wafers). Surface preparation of these advanced materials is usually essential to exploiting their enhanced properties in engineering applications. This project concerns the development of a new, low temperature material processing technique using impulsive shock waves of liquid vapour as a generic manufacturing tool, called material processing by laser induced droplet vaporisation (LIDV). LIDV uses a pulsed laser to vaporise a stream of droplets to produce a succession of impacting shock waves at the surface of the component of interest. By exploiting the precision of modern droplet generation technologies with the power and control of a laser source, well-regulated impulsive forces can be achieved at a level sufficient to remove surface contaminants and/or to modify the surface mechanical properties (roughness and hardness). The project will undertake proof-of-principle experiments to establish the benefits of LIDV as a means to clean and modify the surface of CFRP. CFRP presents a particular problem since a multi-stage surface preparation process is required as all traces of surface contaminants and chemical agents that are exhumed during production must be removed before final assembly. It is expected that the LIDV process could provide more accurate and efficient surface modification of high performance materials than at present and that it will also open the door for exciting breakthroughs in peening, thin films transfer, hardening and alloying.

人们对高性能材料的需求不断增加，其中许多与传统制造过程不符，因为它们对热量和磨损的敏感性（例如碳纤维增强聚合物（CFRP），聚合物，薄膜，半导体Wafers）。这些高级材料的表面制备通常对于利用其在工程应用中增强的性能至关重要。该项目涉及使用液体蒸气的冲动性冲击波作为一种通用制造工具的新型低温材料处理技术的开发，称为激光诱导的液滴蒸发（LIDV）称为材料处理。 LIDV使用脉冲激光蒸发液滴流，以在感兴趣的组件表面产生一系列撞击的冲击波。通过用激光源的功率和控制来利用现代液滴产生技术的精度，可以在足以消除表面污染物和/或修改表面机械性能（粗糙度和硬度）的水平上实现良好调节的冲动力。该项目将进行原则证明实验，以确定LIDV的好处，以清洁和修改CFRP的表面。 CFRP提出了一个特定的问题，因为需要多个阶段的表面制备过程，因为必须在最终组装之前去除生产过程中挖掘出的所有表面污染物和化学药品的痕迹。预计LIDV工艺可以比目前提供更准确，更有效的高性能材料表面修饰，并且还将为令人兴奋的烤制，薄膜传输，硬化和合金启动打开大门。
