摘要

拉伸强度差和脆性被认为是环氧树脂的一个主要弱点。本文采用热重分解法研究了氧化钙的添加对环氧树脂热降解的影响。以环氧树脂为基体材料，制备了氧化钙含量分别为5%、7.5%、10%和15wt%的四种复合材料。使用阿伦尼斯方程来评估复合材料的活化能，并将结果制成表格。研究结果表明，添加氧化钙作为填料有助于通过抑制环氧树脂的热分解过程来提高部件的热稳定性。氧化钙/环氧树脂比例为10%（重量）的组合物显示出良好且明显的稳定性，与其他复合材料相比，10%CaO填料/环氧树脂复合材料在400°C下的热分解增加证明了这一点。图形摘要

Study the Thermal Properties of Epoxy Resin Reinforced with Calcium Oxide Fibers

ABSTRACT Poor tensile strength and brittle nature are considered to be a major weakness in epoxy resin. Herein, thermogravimetric decomposition is used to investigate the effect of the addition of calcium oxides on the thermal degradation of the epoxy resin. Four composites with 5%, 7.5%, 10%, and 15 wt % calcium oxide are prepared with epoxy resin as a matrix substance. Arrhenius equation is used to evaluate the activation energies of the composites and the findings are tabulated. The findings indicate that the addition of calcium oxides as a filler contributes to an enhancement in the thermal stability of the components by inhibiting the process of thermal decomposition of epoxy resin. The composition with a ratio of 10% by weight of calcium oxide/epoxy shows a good and distinct stability, which is evidenced by the increasing in the thermal decomposition of the composite 10% CaO filler/epoxy at 400°C compared with other composites.
