Fiber-reinforced plastics (frp) are ideally suited as material for high-pressure vessels. The orthotropic material properties allow to match the biaxial stress condition. This enables a lightweight design for pressure vessels, which is already widely used due to the significant weight reduction and the excellent resistance of frp to corrosion.Driven by strict recycling regulations in the automotive sector, the spreading of thermoplastic pre-pregs and the desire for an increase of functionality of pressure vessels, a new design for high-pressure containers will be developed. The new design thereby will compensate the disadvantages of the state of the art design of frp pressure vessels.The objective of this research project is a design study for modular high-pressure vessels. The aim of a new frp-design is to provide recyclable pressure vessels that furthermore simplify the connection to surrounding structures. The accessibility of the interior of the pressure vessel will be achieved through the modularity of the design. Cylinder and end closure will be manufactured separately, and thereby the functionality of the vessel will be increased. Due to the access of the interior the concept can be used to design piston accumulators, hydraulic accumulators and hydrogen storage with metal hydrides. In order to achieve these advantages, a study of different concepts for end closures for modular pressure vessels and the corresponding joining techniques has to be carried out.

纤维增强塑料（frp）是高压容器的理想材料。正交各向异性材料特性允许匹配双轴应力条件。这使得压力容器的轻量化设计成为可能，由于玻璃钢的显著减重和优异的耐腐蚀性，这种设计已经得到广泛应用。在汽车行业严格的回收规定、热塑性预浸料的普及以及对压力容器功能性的需求的推动下，将开发新的高压容器设计。因此，新的设计将弥补玻璃钢压力容器设计的缺点。本研究项目的目标是模块化高压容器的设计研究。一个新的玻璃钢设计的目的是提供可回收的压力容器，进一步简化连接到周围的结构。压力容器内部的可达性将通过设计的模块化来实现。圆筒和端盖将单独制造，从而增加容器的功能。由于内部的访问，该概念可用于设计活塞环，液压环和金属环的储氢。为了实现这些优点，必须对模块化压力容器端盖的不同概念和相应的连接技术进行研究。
