ABSTRACT

In this work, characterization of polymer matrix composites was carried out. Thermoplastic polymers were used as a matrix. Nondestructive Young’s modulus values were compared with the destructive values. Differences between the destructive and nondestructive values are less than 10%. Reinforcements increased Young’s modulus. The principal strain values of the glass fiber-reinforced polymethylmethacrylate (PMMA) composites were higher than that of graphite-reinforced PMMA composites. Radiography and tomography methods were used for the characterization. Specimens consisted of homogeneously distributed reinforcements. Imaging behavior was appropriate. There are no cracks or pores according to radiography. Specimens consisted of homogeneously distributed reinforcements.

摘要

在这项工作中，进行了聚合物基复合材料的表征。热塑性聚合物用作基质。将非破坏性杨氏模量值与破坏性值进行比较。破坏性值与非破坏性值之间的差异小于10％。增强增加了杨氏模量。玻璃纤维增​​强的聚甲基丙烯酸甲酯（PMMA）复合材料的主应变值高于石墨增强的PMMA复合材料。放射线照相和断层摄影方法用于表征。标本由均匀分布的钢筋组成。影像学表现是适当的。根据射线照相，没有裂缝或气孔。标本由均匀分布的钢筋组成。
