Abstract

Continuous Fiber Reinforced Polymer (CFRP) tubular structures are widely used due to their lightweight and superior mechanical performance. However, rapid and cost-effective methods for fabricating small-to-medium sized CFRP tubular structures remain scarce. This study presents a novel Rotary Additive Manufacturing (RAM) system that utilizes a coextrusion process and a 4-axis motion system to fabricate grid-stiffened CFRP tubular structures with complex stiffener designs. Compression performance was evaluated through experimental tests and high-fidelity simulations, examining the effects of grid-stiffening, stiffener pattern, and thickness. The results validate the effectiveness of CFRP stiffeners, as evidenced by significantly improved peak force and specific energy absorption(SEA). Additionally, the ability to tune the mechanical performance of these structures by optimizing the stiffener design was demonstrated. The proposed design and fabrication process enables the creation of high-performance and innovative grid-stiffened CFRP tubular structures for applications such as aircraft fuselages, prosthetic sockets, and beyond.

网格加筋连续纤维增强聚合物管状结构的旋转增材制造

连续纤维增强聚合物（CFRP）管状结构因其重量轻、力学性能优越而得到广泛应用。然而，制造中小型碳纤维增强塑料管状结构的快速和经济有效的方法仍然很少。本研究提出了一种新型的旋转增材制造（RAM）系统，该系统利用共挤压工艺和四轴运动系统来制造具有复杂加强筋设计的网格加筋CFRP管状结构。压缩性能通过实验测试和高保真模拟来评估，检查网格加劲、加劲器模式和厚度的影响。结果验证了CFRP加强筋的有效性，其峰值力和比能吸收（SEA）显著提高。此外，通过优化加强筋设计来调整这些结构的机械性能的能力也得到了证明。提出的设计和制造工艺能够创造高性能和创新的网格强化CFRP管状结构，用于飞机机身，假肢插座等应用。
