Abstract

In this study unreinforced and reinforced samples with uncoated and coated woven carbon fibres (WCF) with alumina (Al2O3) and tri calcium phosphate (TCP) powders were incorporated into heat polymerised polymethyl methacrylate (PMMA) denture base resin in addition to poly vinyl alcohol (PVA) with 0.02 and 0.09 weight fraction (wi). Impact, flexural strength and water absorption of layered denture base resin have been studied. Surface morphology of the coating layers has been examined by field emission-scanning electron microscope (FE-SEM) and the toxicity of reinforcing materials were also investigated in human blood cells. Uncoated WCF sample showed high impact and flexural strength, but it still exhibits poor aesthetic. A significant increase of the impact strength values was observed in the coated specimens, in expense of flexural strength. The effect of TCP on PMMA resin was higher than when using alumina particles. Aesthetic, impact and flexural strength have improved together when PVA increased.

氧化铝和磷酸三钙复合碳纤维层对义齿基托力学性能的影响

在这项研究中，除了具有0.02和0.09重量分数（wi）的聚乙烯醇（PVA）外，还将具有氧化铝（Al2O3）和磷酸三钙（TCP）粉末的未涂覆和涂覆的编织碳纤维（WCF）的未增强和增强样品掺入热聚合聚甲基丙烯酸甲酯（PMMA）义齿基托树脂中。研究了层状义齿基托树脂的冲击性能、弯曲强度和吸水性。用场发射扫描电子显微镜（FE-SEM）研究了涂层的表面形态，并研究了增强材料在人体血细胞中的毒性。未涂覆的WCF样品显示出高的冲击和弯曲强度，但其仍然表现出较差的美观性。在涂层试样中观察到冲击强度值的显著增加，这是以弯曲强度为代价的。TCP对PMMA树脂的影响比使用氧化铝颗粒时更大。当PVA增加时，美观性、冲击性和抗弯强度共同提高。
