Composites age through cracking, delamination, moisture, fatigue, thermal stress, and UV degradation—often simultaneously.
ElastoSure K-Load models these coupled mechanisms. K-Flash handles rapid events like pyrolysis and ablative recession, while K-Fail converts degradation into remaining useful life.

What Is Composite & Fiber-Reinforced Polymer Aging?
Composite aging begins at the microstructural scale. The polymer matrix degrades, the fiber-matrix interface weakens, and damage accumulates across the laminate through micro-cracks and delamination.
Traditional fatigue tests provide design allowables, but not how those values change over years of moisture, thermal cycling, and real-world loading. ElastoSure models that degradation over the structure’s service life.
Moisture is a major driver. Water plasticizes the resin, lowers glass transition temperature (Tg), and weakens the fiber-matrix interface. Combined with thermal cycling and fatigue, these effects become synergistic—not simply additive.
