Design of Composite Structures for Sustainability and Recyclability

回收、可持续性和环境友好性对复合材料领域来说是相对较新的。在航空航天和汽车工业，他们开始意识到需要一种更平衡的方法来设计和制造这些材料。有很多方法可以使复合材料更加环保。一是在可持续结构设计中使用天然纤维复合材料。另一种方法是利用航空航天工业中典型的许多复合材料制造过程中固有的废物：预浸料切断物、废弃零件和零件修整物。利用这些废物，不仅可以节省成本，还可以减少不可用废物的产生。因此，应该在两个方面进行重要的研究：(1)可持续设计可以通过使用更具可持续性的基础材料来实现；(2)对于那些不可持续性的材料，然后找到回收和再利用的方法。所涉及的科学是调整当前的建模和测试方法，以改进可回收和可持续材料的设计和制造，这些材料与常规复合材料的基本形式并不完全相同。该方法必须使用先进的材料模型、材料和工艺表征设备以及整体可持续的设计方法。

Recycling, sustainability and environmental friendliness are relatively new to the world of composite materials. In aerospace and automotive industries, they are beginning to realize the need for a more balanced approach to design and manufacturing with these materials. There are ways to make composites more environmentally friendly. One is to use natural fiber composite materials in the design of sustainable structures. Another is to make use of the waste that is inherent to many composite manufacturing processes typical of the aerospace industry: prepreg cutoffs, rejected parts and part trimmings. Make use of the waste, then it would not only save on cost but would also lower the production of non-useable waste materials. There are thus two fronts where important research should be conducted: (1) sustainable design can be achieved by making use of more sustainable base materials, and (2) for those materials that are not sustainable, then find a way to recycle and reuse them. The science involved is to adapt current modeling and testing methods to improve the design and manufacturing of recycled and sustainable materials, which are not quite in the same basic form as regular composite materials. The approach must use advanced material models, material and process characterization equipment and an overall sustainable design approach.
