Epoxy composites of reduced flammability - ScienceDirect

The contemporary planes built up from composites have their weight reduced by 25–45% and, hence, they reach longer distances having reduced fuel consumption. Epoxy laminates reinforced with carbon fibers constitute an important group among the composites used in the aviation industry [1] .
