Abstract

This paper describes design, manufacture, and testing of a linerless composite vessel for liquid hydrogen, having 0.3 m diameter and 0.9 m length. The vessel consists of a composite cylinder manufactured by wet filament winding of thin-ply composite bands, bonded to titanium end caps produced by additive manufacturing. The aim was to demonstrate the linerless design concept with a thin-ply composite for the cylinder. The investigation is limited to the internal pressure vessel, while real cryogenic tanks also involve an outer vessel containing vacuum for thermal insulation. Thermal stresses dominate during normal operation (4 bar) and the layup was selected for equal hoop strains in the composite cylinder and end caps during filling with liquid hydrogen. Two vessels were tested in 20 cycles, by filling and emptying with liquid nitrogen to 4 bar, without signs of damage or leakage. Subsequently, one vessel was tested until burst at almost 30 bar.

无衬里液氢复合罐的设计、制造和低温测试

摘要本文介绍了一个直径 0.3 米、长度 0.9 米的无内衬液氢复合容器的设计、制造和测试。该容器由一个复合材料圆筒组成，圆筒通过湿法缠绕薄层复合材料带制造而成，并与增材制造的钛合金端盖粘接在一起。其目的是展示使用薄层复合材料制造圆筒的无衬垫设计理念。调查仅限于内部压力容器，而真正的低温罐还包括一个用于隔热的真空外容器。在正常运行期间（4 巴），热应力占主导地位，在充填液氢时，复合材料筒体和端盖的环向应变相等，因此选择了这种铺层方式。对两个容器进行了 20 次循环测试，即充入和排空液氮至 4 巴，未发现损坏或泄漏迹象。随后，一个容器在接近 30 巴的压力下测试至爆裂。

期刊介绍： Applied Composite Materials is an international journal dedicated to the publication of original full-length papers, review articles and short communications of the highest quality that advance the development and application of engineering composite materials. Its articles identify problems that limit the performance and reliability of the composite material and composite part; and propose solutions that lead to innovation in design and the successful exploitation and commercialization of composite materials across the widest spectrum of engineering uses. The main focus is on the quantitative descriptions of material systems and processing routes. Coverage includes management of time-dependent changes in microscopic and macroscopic structure and its exploitation from the material''s conception through to its eventual obsolescence.
