Some factors that affect the sealing properties of the joint are the material of the gasket, the shape of the gasket and the clamped flanges but also the stiffness of the whole assembly.
Future Enhancements In the last several decades, the science and engineering community has progressively ventured outside of traditional boundaries in terms of materials, loads, configurations etc., for structural systems in mechanics.
By using this method another variable inputs could be taken into account, for instance applied loads (pressure applied to the cores of the unit), material properties of the gasket and of the other parts of the assembly as well etc.

To overcome these limitations the materials of the textile reinforcements are not only used because of their excellent structural properties and durability, but also because of additional functional properties (e.g. strain or damage sensing).
Materials and Methods Materials.
The woven 3D-textile reinforcement was manufactured by using the above described materials on a modified rapier weaving machine (Lindauer DORNIER GmbH, Germany) with a linear take-off (Kieselstein GmbH, Germany).
Due to the high strain rate, the mechanical properties of the materials are increasing, causing an overall improved composite behaviour e.g. by an increased mechanical anchorage of the 3D-textile reinforcement to the SHCC matrix.
