Developmental use of recycled carbon fibers in aricraft, helicopter and train secondary structures

贝尔直升机德事隆加拿大公司、庞巴迪航空航天公司和庞巴迪运输公司正在联合他们的力量参加CDCQ，以验证回收碳纤维在大型复合材料部件中的使用。贝尔直升机公司和庞巴迪宇航公司都是碳纤维部件的用户，并产生碳纤维废料。这三个工业合作伙伴正在寻找低成本的解决方案来减轻重量，在他们的产品中引入交联碳纤维很可能是解决方案。环境的可持续性对所有人来说都是一种价值。通过开发一种回收碳纤维的方法来减少他们的环境足迹，这是朝着循环经济模式方向迈出的一步。许多研究团队和实验室都在尝试将航空航天工业中废弃的碳预浸料回收利用。然而，这些努力迄今为止尚未成功，因为碳复合材料零件的1级、2级和3级供应商未能证明这些材料适用于相关应用，并且供应链能够在较长时间内维持生产。因此，第一步是通过展示用这些废弃材料生产的零件的价值和性能，来创造一种动力，使碳纤维废料在当地得到利用。一旦这些事实得到证实，将有利于重新使用这些纤维。原始设备制造商将能够开始分类和重新评估自己的废物，由碳纤维预浸料废料和零件切边制成。

Bell Helicopter Textron Canada, Bombardier Aerospace and Bombardier Transportation are joining their forcesto the CDCQ to validate the use of recycled carbon fibers in large composite parts. Bell Helicopter andBombardier Aerospace are both user of carbon fibers in their parts and generate carbon fiber wastes. Thesethree industrial partners are looking for low cost solutions to reduce weight and the introduction of recycledcarbon fibers in their products could very well be the solution. Environmental sustainability is a value for all ofthem. Reducing their environmental foot print by developing a way to recycle carbon fibers that wouldotherwise go to the landfill is one step in the direction of a circular economy model. Many research team andlab are attempting to revalorize waste carbon prepreg from the aerospace industries. However these effortshave been unsuccessful so far because the tier 1, 2 and 3 suppliers of carbon composites parts have not beenable to demonstrate that these materials are suitable for relevant applications, and that the supply chain is inplace to sustain production over an extended period. Therefore the first step is to create a momentum to locallyvalorize carbon fiber waste by demonstrating the value and performance of parts produced with these recycledmaterials. Once these facts are proven, it will be beneficial to reuse these fibers. The OEMs will be able toinitiate the sorting and revalorization of their own waste, made of carbon fibers prepreg scraps and parttrimmings.
