Braided Composites for Aircraft Fuselage Frames

今天的飞机是用坚固而轻便的复合材料制造的。目前的制造技术主要局限于劳动密集型的一层一层地沉积聚合物预浸层，然后**在昂贵的高压罐中固化聚合物。航空航天工业正在寻求降低制造**复合材料结构部件的成本。航空航天工业承重结构的制造是蒙特利尔理工学院、空间技术中心(CTA)和纺织技术中心(GCTTG)决定与庞巴迪航空结构和工程服务公司(BAES)合作使用新技术来解决的**挑战。该项目旨在开发一种使用定制的自动编织技术和结构注塑**成型工艺来制造**复合材料飞机机身骨架的工艺。该项目将确定飞机机身框架的设计包络，建立编织**纺织结构的模型，开发编织技术，开发非高压灭菌器浸泡技术，**生产编织C框架演示器并评估成本。编织C形框**制造的项目提案将培养大学和学院层面的高素质人才。它还将在学术界和产业界之间创造**巨大的知识转移机会。通过帮助生产更便宜、更安全、更轻、更环保的飞机，结果将对BAES和加拿大非常有利。

Today's aircrafts are built using strong and lightweight composite materials. Current manufacturing techniques**are mostly limited to labor intensive layer-by-layer deposition of polymer pre-impregnated plies followed by**polymer cure in an expensive autoclave cure. Aerospace industry is looking to reduce the costs for fabricating**composite structural components. Manufacturing of load-bearing structure in the aerospace industry is a**challenge that Polytechnique Montreal, Centre technologique en aérospatiale (CTA) and Center for Textile**Technologies (GCTTG) decided to address using novel technologies in partnership with Bombardier**Aerostructure and Engineering Services (BAES). This project aims at developing a process to manufacture**composite aircraft fuselage frames using tailored automated braiding technologies and structural infusion**molding process. This project will define the design envelope for aircraft fuselage frames, model braided**textile architectures, develop the braiding technology, develop the out-of-autoclave infusion technology,**produce braided C-frame demonstrators and evaluate the costs. The project proposal on braided C-frame**manufacturing will train highly qualified personnel at both the university and college level. It will also create**great knowledge transfer opportunities between academia and industry. The outcomes will be highly beneficial**to BAES and Canada by helping to produce cheaper, safer, lighter and greener aircrafts.
