Multi-load generating device for testing of stability of flexible textile laminate under loading condition, has load generating mechanisms exerting force simulating load condition e.g. cyclic stress

摘要

The device (10) has load generating mechanisms operated independent of each other, where each mechanism exerts force simulating a load condition in the form of shear stress in a plane, cyclic stress, gas permeability, film separation or delamination. The mechanisms include a load-producing main mechanism for testing two orthogonal loading ratios, where the loads generated by the mechanisms are individually controllable. Permeability of nitrogen, air, helium or hydrogen on a material i.e. flexible textile laminate is tested. An independent claim is also included for a method for testing of a performance parameter of a material.
