Depolymerizable bio-based multifunctional closed loop recyclable epoxy systems for energy efficient structures

材料，特别是先进材料，是工业社会的支柱和繁荣之源“(材料2030宣言)。绿色协议和数字十年为欧洲确立了高度优先的政策，在欧洲，70%的技术创新直接或间接归因于先进材料。轻质和高强度材料在建造节油和高性能的交通结构中一直发挥着关键作用。轻质材料，如玻璃和碳纤维复合材料，由于其固有的性能，如高机械性能，被广泛使用。然而，较差的可回收性和回收方面构成了一个重大挑战。这些材料的寿命结束方面是至关重要的，因为当填埋时，它们会向环境中释放有毒物质。此外，最大限度地减少制造过程中的资源消耗和能源，优化未来先进材料的废物处理，有助于降低成本和产品在全球生命周期中的端到端足迹，从而显著改善其整体环境性能。REPOXYBLE将创造一种新的高性能材料--生物基环氧复合材料，目标是降低成本和能源效益、可回收利用和可持续发展。REPOXYBLE采用上游方法，比必须在产品开发过程结束时解决缺陷更有效率和效果。这种方法综合了产品性能、多功能性、可持续性、安全性和潜在的法律问题，同时仍有时间在单体合成、树脂配方和未来的复合材料设计方面采取行动。REPOXYBLE是由航空航天和汽车行业的两个互补市场应用推动的。

Materials, especially advanced materials, are the backbone and source of prosperity of an industrial society” (Materials 2030 Manifesto). The Green Deal and the Digital Decade establish high-priority policies for Europe, where 70% of all technical innovations are directly or indirectly attributed to advanced materials. Lightweight and high-strength materials have consistently played a key role in the construction of fuel-efficient and high-performing transportation structures. Lightweight materials such as glass and carbon fibres composites are commonly used due to their intrinsic properties such as high mechanical performance. However, the poor recyclability and recovery aspect poses a significant challenge. The end-of-life aspect of these materials is crucial, as when landfilled they release toxic substances into the environment. Moreover, minimising resource use, energy of manufacturing processes and optimising waste disposal of future advanced materials can help mitigate cost and product’s end-to-end footprint acrossits global lifecycle, thereby significantly improving its overall environmental performance. REPOXYBLE will create a new class of high-performance materials -bio-based epoxy compositestargeting cost and energy effectiveness, recyclability and sustainability. REPOXYBLE assumes an upstream approach more efficient and effective than having to address deficiencies at the end of the product development process. This approach integrates product performance, multifunctionality, sustainability, safety and potential legal concerns, while there is still time to act, on the monomers’ synthesis, the resin formulation and the future composite design. REPOXYBLE is driven by two complementary market applications in the aerospace and automotive sectors.
