چکیده
|
Hollow glass beads and graphene were used to improve the performances of the epoxy resin. the density,tensile,compressive properties and thermal behaviors of the as-prepared samples were discussed. experiment results showed that hollow glass beads could effectively reduce the density of the epoxy resin matrix. when the hollow glass beads loading was 30 wt%,the density of the composites was 0.81 g·cm-3. moreover,graphene could enhance the mechanical performances of the foamed composites. when the graphene loading was 0.75 wt%,the tensile strength,young's modulus and strain break of the epoxy/hollow glass beads/graphene ternary samples were 85.2 %,53.4 % and 11.0 % more than the control binary sample,respectively. moreover,the compressive strength and modulus were 10.8 % and 68.6 % more than the control binary sample,respectively. in addition,dsc and tg results showed that graphene could accelerate the curing and improve the thermal stability of the foamed composites.
