Thermomechanical Properties of Carbon Fabric Reinforced Epoxy Laminates with h-BN and MoS2 Fillers

Abstract This work endeavors to investigate thermomechanical performance of carbon fabric reinforced epoxy composite (CEC) with fillers – hexagonal boron nitride (h-BN) and molybdenum disulfide (MoS2). The filler 2, 4, 6, 8 Wt.% was dispersed precisely in the resin through magnetic stirring ultrasonication, prepared loaded CEC using vacuum bag technique studied behavior at an elevated temperature by dynamic mechanical analysis. 6 MoS2-CEC showed 70% enhancement storage modulus since networks increased stiffness. increase G-band intensity Raman spectra composites confirmed improved matrix-fiber stress transfer. 4 BN-CEC revealed highest glass-transition 92°C. thermogravimetric analysis exhibited a two-step thermal decomposition: matrix (nearby 260°C) fibers (beyond 420°C). maximum degree crosslinking, twice neat CEC, MoS2 restrained mobility chains decreased decomposition. Both have comparable stability are significantly than CEC. Thus, containing solid lubricant up shall be used for high-temperature applications.
