The aim of the present study was to investigate the effect of the addition of different types of fibres on the transverse and impact strength of acrylic resin denture base material. The addition of glass fibres (strand) and polyethylene fibres produced a non significant increase in the modulus of elasticity, compared with the control of conventional heat-cured acrylic resin. The addition of glass fibres (woven and strand), polyethylene and carbon fibres to acrylic resin produced a non significant increase in the modulus of rupture. The addition of carbon, glass (strand) and polyethylene fibres produced a significant increase in the impact strength. Within the limitations of this study the addition of silk fibres did not produce an improvement in the mechanical properties.
本研究的目的是调查添加不同类型纤维对丙烯酸树脂义齿基托材料横向强度和抗冲击强度的影响。与传统热固化丙烯酸树脂对照组相比，添加玻璃纤维（股状）和聚乙烯纤维使弹性模量有不显著增加。向丙烯酸树脂中添加玻璃纤维（编织状和股状）、聚乙烯和碳纤维使断裂模量有不显著增加。添加碳、玻璃（股状）和聚乙烯纤维使抗冲击强度有显著增加。在本研究的局限性范围内，添加丝纤维并未使机械性能得到改善。
