Analyzed theoretical and empirical reinforcement mechanisms, including load transfer, dislocation strengthening, grain refinement, and precipitation hardening.
Poor wettability between carbon fibers and aluminum matrices drives brittle interfacial Al4C3 formation, which serves as a major site of structural failure.
Engineered fiber coatings significantly mitigate interfacial reactions while enhancing composite mechanical properties through coordinated load transfer, dislocation accumulation, and matrix grain refinement.
