Composites have been used for many years in small recreational and high-performance boat industries. Their widespread acceptance in the boat industry is due to their light weight, vibration damping properties, corrosion resistance, high impact strength, design flexibility, low fabrication costs and ease of maintenance and repair. The use of lightweight composite materials in constructing larger marine structures is increasing in recent times. Ther-mosetting composites, the usual candidates for constructing boats, are non-recyclable in nature and their use in larger marine structures is not a justifiable solution. This will add the environmental burden and is not de-sired. These issues are also causing problems for the usage of composites in marine renewable energy structures such as tidal and wind turbine blades.We need to develop next generation of recyclable, lightweight composite materials that would be a more sustain-able solution for the environment. Newly introduced liquid thermoplastic acrylic resin based composites are a po-tential candidate for such applications. This liquid resin is processed in the same way as the traditional thermoset-ting resins used in boat building and wind turbine blade industries, features high mechanical properties, but is re-cyclable unlike thermosetting composites. This recyclability can provide an answer to the major issue of the treat-ment of end-of-life composites.The construction of large marine structures with liquid thermoplastic resin based composite materials represents a challenging task. This project will focus on potential development of liquid acrylic resin based composites for ma-rine and ship building and for renewable energy structures. This will involve manufacturing acrylic matrix compo-sites and studying their physical and mechanical properties. This will also involve studying the fibre/matrix interface in dry condition as well as after seawater immersion. There will be investigations on the welding/joining and repair-ing potential of this new composite system. The fire resistance property will be investigated in collaboration with Fire Safety Engineering Laboratory at the University of Edinburgh. Finally, a demonstrator will be manufactured in conjunction with industry.

复合材料已在小型娱乐和高性能船舶工业中使用多年。它们在船舶工业中被广泛接受是由于它们的重量轻、振动阻尼性能、耐腐蚀性、高冲击强度、设计灵活性、低制造成本以及易于维护和修理。近年来，轻质复合材料在建造大型海洋结构物中的使用越来越多。热固性复合材料，通常的候选人建造船只，是不可回收的性质和他们的使用在较大的海洋结构是不合理的解决方案。这将增加环境负担，是不可取的。这些问题也给海洋可再生能源结构（如潮汐和风力涡轮机叶片）中复合材料的使用带来了问题。我们需要开发下一代可回收的轻质复合材料，这将是对环境更具可持续性的解决方案。新推出的液体热塑性丙烯酸树脂基复合材料是一个潜在的候选人，这样的应用。这种液体树脂的加工方式与造船和风力涡轮机叶片行业中使用的传统热固性树脂相同，具有高机械性能，但与热固性复合材料不同，可重复循环。这种可回收性可以解决废旧复合材料处理的主要问题。用液体热塑性树脂基复合材料建造大型海洋结构是一项具有挑战性的任务。该项目将重点关注液体丙烯酸树脂基复合材料的潜在开发，用于海洋和船舶建造以及可再生能源结构。这将涉及制造丙烯酸基质复合材料，并研究其物理和机械性能。这也将涉及研究干燥条件下以及海水浸泡后的纤维/基体界面。将对这种新的复合材料系统的焊接/连接和修理潜力进行调查。耐火性能将与爱丁堡大学消防安全工程实验室合作进行研究。最后，将与工业界一起制造一个演示器。
