Pre-impregnated composite materials are strategic enabling inputs for contemporary UAV manufacturing. This paper evaluates prepreg technology trends and export-control implications between 2021 and 2024, using documentary analysis of industrial disclosures, EU dual-use reports, Wassenaar control lists and Czech export-control documentation. The findings show a coupled technological-regulatory trajectory: thermoset and thermoplastic prepregs, OOA processing and AFP/ATL automation advanced alongside stricter compliance governance under Regulation (EU) 2021/821.
