The mean compressive stress in the nth reinforcement (in the ith layer) could be calculated using the following equation:
Both the FKM and HNBR samples show very similar compressive stress relaxation behavior up to 1,360 hours of testing, while HNBR presents a constant sealing force retention (78%) up to 2,500 hours.
The crystalline polymer PET has higher compressive strength and Young's modulus than the amorphous polymer PC, therefore PC particles are prone to deform under the influence of the compressive stress and tensile stress exerted by the matrix during elongation compared to PET particles.
Both figures 5 and 6 show that as the compressive stress increases, the area of the hysteresis loop correspondingly increases.
