Thermoset Prepreg Market Report
“The thermoset prepreg market size will reach USD 5.7 billion in 2026 and offers robust growth opportunities for market stakeholders. With the market expected to grow at a CAGR of 6.5%, the annual sales will hit the USD 7.8 billion mark in 2031, driven by rising commercial and defense aircraft production, sustained defense spending growth, expanding composite intensity in next-generation aircraft programs, and the ongoing substitution of metallic components with lightweight composite structures across automotive and industrial applications. Thermoset prepregs, led by epoxy resin systems, remain the material of record for flight-critical structures thanks to their proven qualification history, exceptional mechanical performance, and decades-long track record across the most demanding aerospace and defense programs.”
