文摘

Both matrix and fiber/matrix interface of carbon/carbon composites were optimized. Radial carbon nanotube (CNT) was grown on carbon fibers (CF) to strengthen matrix. Pyrocarbon layer was introduced between CF and CNT/matrix to optimize interface. Optimal designs endowed composite with improved strength, ductility and toughness.
