Özet
Bulk molding compound (BMC) composites are widely used in engineering applications; however, improving their mechanical response through low-content nanoscale modification remains challenging for highly filled thermoset molding systems. In this study, Ti3C2Tx MXene was incorporated into an industrial BMC formulation under unchanged compression-molding conditions to investigate its influence on mechanical and microstructural characteristics. The unmodified BMC and composites containing 0.238, 0.476, and 0.714 wt.% MXene were characterized using tensile testing, Izod impact testing, Shore D hardness, FTIR, XRD, TEM, SEM, and SEM–EDS. Ti3C2Tx MXene addition improved the mechanical response within the investigated low-content range. The average tensile strength increased from 14.24 MPa for unmodified BMC to 24.00 MPa for the 0.714 wt.% MXene-added composite, a 68.6% improvement. The tensile modulus increased from 7.85 to 10.14 GPa, absorbed impact energy increased by up to 52.6%, and Shore D hardness increased from 70.6 to 75.8. TEM provided local evidence of MXene-related layered and partially overlapped regions, while SEM–EDS supported Ti-containing MXene-related regions in powder mixtures and molded bulk composites. BMC/MXene-0.71 exhibited the highest average mechanical values, whereas BMC/MXene-0.48 showed a more repeatable mechanical response and a comparatively balanced distribution tendency.
