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联手**参与CDCQ项目，以验证在大型复合材料部件中使用回收碳纤维的可行性。贝尔直升机和庞巴迪航空航天公司都使用碳纤维制造零部件，并产生碳纤维废料。这三家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再生碳纤维很可能是解决方案。环境可持续性是他们所有人的价值观。通过开发一种回收碳纤维的方法来减少他们对环境的影响，否则这些碳纤维将被送往垃圾填埋场，这是朝着循环经济模式迈出的一步。许多研究团队和实验室正试图重新利用航空航天工业中的废碳预浸料。然而，到目前为止，这些努力**并没有成功，因为碳复合材料零件的一级、二级和三级供应商未能**证明这些材料适合相关应用，并且供应链已到位，可以在较长时间内维持生产。因此，第一步是通过展示用这些回收材料生产的零件的价值和性能来创造一种动力，使当地的碳纤维废物增值。一旦这些事实得到证实，这些纤维的再利用将是有益的。原始设备制造商将能够开始对他们自己的废物进行分类和重新估价，这些废物由碳纤维预浸料废料和零件边角料制成。

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