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.

纤维增强的塑料（FRP）非常适合作为高压血管的材料。正性材料特性允许匹配双轴应力条件。这使压力容器具有轻巧的设计，由于重量的显着减轻和FRP对腐蚀的极大阻力，该设计已被广泛使用。由汽车部门严格的回收法规驱动，热塑性Pre-Pregs的扩散以及渴望的扩散压力容器功能的增加，将开发用于高压容器的新设计。因此，新的设计将补偿FRP压力容器最新设计状态的缺点。该研究项目的目的是用于模块化高压容器的设计研究。新的FRP设计的目的是提供可回收压力容器，从而简化与周围结构的连接。压力容器内部的可及性将通过设计的模块化来实现。气缸和末端闭合将分别制造，从而增加容器的功能。由于内部的获取，该概念可用于设计活塞蓄能器，液压蓄能器和用金属氢化物储存氢。为了实现这些优势，必须对模块化压力容器的最终封闭概念和相应的连接技术进行研究。
