摘要

在本工作中,使用压模法开发了复合材料,其组成为M2A1C(环氧树脂+2wt%MWCNT+1wt%Al2O3)、M2A1.5C(环氧树脂+2 wt%MWCNT+15wt%Al2O3。从组成来看,与M2A1C相比,M2A1.5C在拉伸强度、弯曲强度和冲击强度方面分别提高了30%、24%和28%的机械性能。从热重分析来看,在Al2O3含量增加的过程中发生了临界变化,但与其他复合材料相比,M2A1.5C在残余质量和最高温度分解方面有显著改善。由于复合材料中材料的低密度,M2A1C组合物中的疏水性降低。这项研究正在探索改进聚合物-金属基杂化复合材料的方法,使其更轻、更实惠,并更容易在轻负载应用中使用。

Investigation of mechanical, thermal and water absorption behaviour of MWCNT’s with AL2O3 reinforced polymer composite
In this work, composite materials were developed using compression moulding method, which the composition of M2A1C (Epoxy + 2 wt % MWCNT +1 wt % Al2O3), M2A1.5C (Epoxy + 2 wt % MWCNT +1.5 wt % Al2O3) and M2A1C (Epoxy + 2 wt % MWCNT +2 wt % Al2O3). From the composition, M2A1.5C had improved the mechanical properties of 30%, 24% and 28% in tensile strength, flexural strength and impact strength, respectively, compared to the M2A1C. From the thermo-gravimetric examination, the critical change was happened during increasing of Al2O3, however, the M2A1.5C had a significant improvement within the residual mass and maximum temperature decomposition with compared to other composites. Hydrophobicity decreased in the M2A1C composition, due to the low density of the material in the composite. The study is exploring ways to improve the polymer-metal matrix hybrid composite materials to make them lighter and more affordable, as well as easier to use in light load applications.
