Abstract To obtain uniform and controllable material removal on hard and brittle materials, a novel processing technology with functionally graded lapping and polishing plate (FG-LPP) was proposed. Taking application of particles/rubber composites and adjustable contact stress of workpiece as key point, the abrasive particles and rubber were mixed with different mass ratios; then the FG-LPP was formed with characteristics of required quasi-continuous distribution of Young’s modulus in the radial direction by two-step processing technique. The properties of Young’s modulus, loss factor, and glass transition temperature of different particles/rubber composites were tested and calculated. Through comparison and analysis, silicon carbide (SiC)/chloroprene rubber (CR) composites are the suitable application object of FG-LPP. Moreover, by laser particle size analyzer, scanning electron microscope, and X-ray diffraction, the size distribution of abrasive particles, micromorphology of particles/rubber composites and their phase composition were tested respectively to better reveal the structure and properties. The test results indicate that under the action of ZnO and MgO, CR undergoes a vulcanization reaction gently and forms a spatial three-dimensional structure. Thus, it helps to increase the intermolecular distance and weaken the intermolecular forces because the NO is easy to enter the CR molecules, which improves the intermiscibility between SiC and CR.

颗粒/橡胶复合材料应用于功能梯度研磨抛光板的结构与性能

摘要 为了在硬脆材料上获得均匀可控的材料去除率，提出了一种新的功能梯度研磨抛光板（FG-LPP）加工工艺。以颗粒/橡胶复合材料的应用和工件接触应力可调为重点，将磨料颗粒与橡胶按不同质量比混合；然后通过两步加工技术形成具有所需杨氏模量在径向上准连续分布特性的FG-LPP。测试并计算了不同颗粒/橡胶复合材料的杨氏模量、损耗因子和玻璃化转变温度的性能。通过对比分析，碳化硅（SiC）/氯丁橡胶（CR）复合材料是FG-LPP的合适应用对象。而且，通过激光粒度分析仪、扫描电子显微镜和X射线衍射分别测试磨料颗粒的粒度分布、颗粒/橡胶复合材料的微观形貌和相组成，以更好地揭示其结构和性能。试验结果表明，在ZnO和MgO的作用下，CR发生温和的硫化反应，形成空间三维结构。因此，由于NO容易进入CR分子中，从而有助于增加分子间距离并减弱分子间作用力，从而提高了SiC和CR之间的互溶性。分别测试了颗粒/橡胶复合材料的微观形貌及其相组成，以更好地揭示其结构和性能。试验结果表明，在ZnO和MgO的作用下，CR发生温和的硫化反应，形成空间三维结构。因此，由于NO容易进入CR分子中，从而有助于增加分子间距离并减弱分子间作用力，从而提高了SiC和CR之间的互溶性。分别测试了颗粒/橡胶复合材料的微观形貌及其相组成，以更好地揭示其结构和性能。试验结果表明，在ZnO和MgO的作用下，CR发生温和的硫化反应，形成空间三维结构。因此，由于NO容易进入CR分子中，从而有助于增加分子间距离并减弱分子间作用力，从而提高了SiC和CR之间的互溶性。
