NOVEL MANUFACTURING METHODS FOR THE INCLUSION OF SELF-HEALING AGENTS FOR AEROSPACE AND AUTOMOTIVE COMPOSITE MATERIALS AND THEIR PROPERTIES

航空航天和汽车复合材料自愈剂的新制造方法及其在自然界中的性质，所有的生物都可以在一定程度上修复/愈合自己。这可能是极端的，就像某些种类的海星重新长出失去的四肢一样，到人类表皮表面划痕的结痂和封闭。这些都是自主神经自我修复的例子。这与复合材料和塑料等现代人造材料形成了鲜明的对比，这些材料一旦损坏，就需要从外部来源进行修复或更换(例如，在金属上焊接，在复合材料结构上打补丁)。这些都是外部治疗的一个例子。建立在自主神经自我修复的过去研究和最新进展的基础上。该项目旨在利用之前对基于Diels-Alder(DA)的共价自适应网络(CAN)的研究来评估它们作为预浸料的适宜性和加工性，以使玻璃层压铝增强环氧树脂(GLARE)等商用系统通过可逆的共价键具有自我修复能力，从而为复合材料提供循环经济。预浸料和复合材料的表征和检测技术(FTIR、NIR、拉曼和超声波)，以查看DA和反向Diels-Alder(RDA)产品以及损伤对结构的影响。DMA/TMA研究确定了不同纤维和固化温度对DA反应对复合材料力学性能的影响，包括。继续进行研究，使用预浸料的流变学研究来表征自愈效率，同时使用更传统的拉伸/压缩测试来确定自愈效率。同时研究了固化和固化后制度对自我修复效率的影响。

Novel manufacturing methods for the inclusion of Self-healing agents for aerospace and automotive composite materials and their properties In nature, all organism can repair/heal themselves to some degree. This can be as extreme as re-growing lost limbs by some species of starfish to the scabbing and sealing of superficial scratches to the epidermis of humans. These are examples of autonomic self-healing. This is in contrast to modern man-made materials like composites and plastics, which once damaged they need fixing or replacing from an external source (e.g. welding in metals, patches on composite structures). These are an example of external healing. Building on past research and recent advances in autonomic self-healing. This project aims to use previous research on Diels-Alder (DA) based covalent adaptable networks (CANs) to assess their suitability and processability as a prepreg to make commercially available systems such as glass laminate aluminium reinforced epoxy (GLARE) with self-healing capabilities through the reversible covalent bonds that could provide a circular economy for composites. Characterisation and detection techniques of both the prepreg and the composite by (FTIR, NIR, Raman and ultrasound) to see DA and reverse Diels-Alder (rDA) products and the effect that damage has on the structure. DMA/TMA studies to determine the effects of the different fibres and curing temperatures on the DA reaction has on the mechanical properties of the composite including. Continued research to use rheological studies on the prepreg to characterise the self-healing efficiencies alongside the use of more traditional tensile/compression testing to determine the self-healing efficiencies. Alongside research into effects of curing and post-curing regimes upon self-healing efficiencies.
