一种由共轭亚麻油（CLO）或共轭大豆油（CSO）、甲基丙烯酸正丁酯（BMA）、二乙烯基苯（DVB）和马来酸酐（MA）共聚物组成的自由基热固性树脂被稻壳加固。将填充量为70 wt %的复合材料进行压缩成型，树脂中共轭油的含量保持在50 wt %不变，改变BMA、DVB和MA的相对含量，得到不同树脂组成的复合材料。通过拉伸试验、DMA、热重分析和索氏萃取等方法，建立了树脂组成与复合材料性能之间的关系。总的来说，在树脂中加入MA后，树脂的力学性能有改善的趋势。所选样品的扫描电镜显示，含ma的复合材料具有更好的填料-树脂相互作用，CLO制备的样品比CSO制备的样品具有更好的性能。©2011 Wiley期刊公司高分子学报，2011
A free radical thermoset resin consisting of a copolymer of conjugated linseed oil (CLO) or conjugated soybean oil (CSO), n-butyl methacrylate (BMA), divinylbenzene (DVB), and maleic anhydride (MA) has been reinforced with rice hulls. Composites containing 70 wt % of the filler were compression molded, the conjugated oil content in the resin was kept constant at 50 wt %, and the relative amounts of BMA, DVB, and MA were varied to afford composites with different resin compositions. Tensile tests, DMA, thermogravimetric analysis, and Soxhlet extraction of the different composites prepared have been used to establish the relationship between resin composition and the properties of the composites. Overall, the mechanical properties tend to improve when MA is introduced into the resin. Scanning electron microscopy of selected samples showed a better filler–resin interaction for MA-containing composites and samples prepared from CLO exhibit better properties than those prepared from CSO. © 2011 Wiley Periodicals, Inc.
