Lightweight composite structures are widely used in aerospace and marine engineering because of their high specific stiffness and strength. However, these structures are highly susceptible to low frequency vibration transmission and airborne noise radiation. Traditional composite designs focus primarily on mechanical performance and lack intrinsic vibration and acoustic control capabilities. Meanwhile, most acoustic or elastic metastructures are fabricated from resins or metals and suffer from limited load bearing capacity. This work presents multifunctional fiber reinforced composite metastructures for integrated vibration attenuation and noise reduction. By combining local resonance mechanisms with acoustic impedance engineering through additive manufacturing, lightweight load bearing structures achieve low frequency bandgaps, broadband sound absorption, and significantly enhanced structural stiffness.
