Influences of MBS on the Interfacial and Mechanical Properties of PC/ABS/Fiber Reinforced Materials
In this study,enhanced polycarbonate(PC)/acrylonitrile-butadiene-styrene copolymer(ABS)/glass fiber(GF)/MBS and PC/ABS/carbon fiber(CF)/MBS blends were successfully fabricated by introducing methyl methacrylate-butadiene-styrene(MBS)copolymer as a compatibilizer.The observations of liquid nitrogen fractured surfaces by scanning electron microscopy(SEM)reveal that the addition of MBS could significantly improve the interfacial adhesion of all alloy materials.The mechanical performance tests indicat that the addition of 1%MBS to the PC/ABS/GF blend could increase the tensile strength,tensile modulus,and notched impact strength by 6.52%,53.87%,and 0.22%,respectively.In the PC/ABS/CF blend,the addition of 3%MBS could improve 10.14%,45.10%,and 0.66%of these properties,respectively.However,due to the low melting point of MBS,its incorporation has a negative impact on the thermal stability of the alloys,leading to a decrease of thermal performance.The study shows that the introduction of MBS could significantly enhance the interfacial bonding and mechanical properties of the PC/ABS matrix.
