Abstract

In this paper some mechanical characteristics of a composite made from a hybrid resin and reinforced with corn cob powder are presented. The hybrid resin was made with a combination between the natural dammar resin combined with a small percentage of acrylic one. The synthetic resin was inserted in order to increase the polymerization process which was produced in about 24 h. In the fist part of the investigation, from the compression test, some mechanical characteristics are determined, such as: breaking strength or maximum force obtained at breaking. Then, by using the SEM analysis and EDS spectrometry, some samples with 50% dammar and 60% dammar were investigated. The last hybrid resin test was Shore D hardness and it was found out that the hardness decreases with the increase of dammar percentage. In the last part of the study, some composites by using the poposed hybrid resin reinforced with corn cob powder were manufactured. It has been found out that the proposed composite reinforced with corn cob powder has increased compression mechanical properties compared other composites that have the same reinforcement.

玉米芯粉增强复合材料复合树脂的力学性能研究

本文介绍了玉米芯粉增强混合树脂复合材料的力学性能。该混合树脂是由天然达玛树脂与少量丙烯酸树脂混合而成。在第一部分的研究中，通过压缩试验，确定了一些力学特性，如:断裂强度或断裂时获得的最大力。然后，利用扫描电镜(SEM)和能谱分析(EDS)对含50%和60% damma的样品进行了研究。最后对混合树脂进行邵氏D硬度测试，发现硬度随损伤百分比的增加而降低。最后，以玉米芯粉为增强材料，制备了几种复合材料。结果表明，玉米芯粉增强复合材料的压缩力学性能比其他相同增强强度的复合材料有所提高。
