The benefits gained from the application of composite materials are well exploited in the hose and pressure vessel industry. In particular the design of pressurised structures has reached the state of maturity and may be regarded as a full covered topic. Novel developments like improved performance vessels and asymmetric structures have led to an increased demand for automation, especially when costs become an issue. In cooperation with the Delft University of Technology and the Taniq BV, a novel structure that relies on an arrangement of optimal isotensoid cells has currently been introduced. This structure enables a new range of high-performance applications where the combination of improved structural efficiency and flexibility is a key achievement. In this paper we outline the design methodology and verification procedure of such structures. The theory covering the mechanics of composite materials serves as a basis for the presented mathematical derivations. By applying this theory, we show that there is still some space to further improve the structural performance of simple geometries like reinforced hoses, especially when regarding the trade off between maximised strength and minimal matrix (e.g. rubber) loading. The equations supporting this trade-off are easily assessable and do immediately provide key conclusions. In addition, since we present the analysis procedure of reinforced hoses as a particular case of the theory for anisotropic shells, an extension to more complicated shapes is rather easy to perform. The created articulated pressurisable structures relying on the presented theory have been tested and found to perform according to the predictions.
