WebShrinkage. Shrinkage is the reduction in volume during cure. Excessive shrinkage will cause internal stresses and serious degradation in the performance of the solidified epoxy. Epoxy systems containing fillers shrink less than unfilled epoxies. As a rule, the higher the filler content the lower the shrinkage. WebThe curing process of polymers/resins in composites introduces volumetric shrinkage, which, based on the component type and boundary conditions, can detriment the strength of the resulting materials and components. In this work, the effect of resin reinforcement (micro- and nanofillers) and curing cycle on curing-induced shrinkage is presented. WebJun 22, 2024 · The shrinkage stress of thermal cured epoxy resin developed during curing process can cause low film adhesion strength, low dimensional accuracy and even … ear shunt surgery
