本文研究了在义齿材料PMMA中添加天然开心果壳粉末的效果。以不同的质量分数（3%、6%、9%、12%）和平均粒径（53μm、106 μm、150 μm、212μm %）加入粉末，研究粉末的抗压强度、表面硬度和密度性能。手铺法是本研究中制备样品的方法。结果采用SPSS （one - way ANOVA）进行统计分析，取平均值，各粒径间差异有统计学意义。PMMA复合材料的抗压强度和表面硬度在填充颗粒（9%wt.）时达到最高值。结果表明，随着填料颗粒质量分数的增加，复合试样的密度值逐渐增大。关键词spmma，开心果壳粉，抗压强度，密度，硬度，生物复合材料引用本文：j . j .

This research had been done to investigate the effect of adding natural powder of Pistachio Shell to PMMA, which popularly used in denture applications. The powder added in different weights fraction (3%, 6%, 9%, and 12%), and different average particle size (53μm, 106 μm, 150 μm, and 212μm %), and studying Compression Strength, Surface Hardness, and Density properties. Hand Lay-Up represented the method used to prepare the specimens in this research. The results were statistically analyzed by SPSS (oneway ANOVA) to determine the mean value and showed a significant difference for each particle size. The highest value of compression strength and surface hardness of PMMA composite specimens happened at (9%wt.) of the filler particles. Also the results represented that the density values for the composite specimens are increased with increasing the weight fraction of the filler particles.
