本研究的目的是评估玻璃纤维分布对常规热固化丙烯酸树脂和自聚合丙烯酸树脂注射成型系统的横向强度和表面光滑度的影响。用两种腈纶材料制备了40个矩形（65x10x2.5 mm）腈纶试样：10个含有5% （w/w）长度为6mm的纤维，10个不含纤维。对试件进行了横向强度试验。从这些样品的破碎和抛光表面提取表面样品，并使用扫描电镜进行评估。发现纤维的添加在统计上显著增加了注射系统的丙烯酸的横向强度。扫描电镜观察表明，玻璃纤维与两种丙烯酸树脂之间具有良好的附着力。玻璃纤维在注射系统中的分布更为均匀。建议采用丙烯酸纤维增强注射系统来减少义齿骨折。
The aim of this study was to evaluate the effect of glass fiber distribution on the transverse strength and surface smoothness of conventional heat cured acrylic and autopolymerizing acrylic of an injection-molding system. Forty rectangular (65x10x2.5 mm) acrylic test specimens were prepared from both acrylic types: 10 with 5% (w/w) 6 mm length fiber and 10 without fiber for both groups. Transverse strength test was applied to these specimens. Surface samples were taken from the broken and polished surfaces of these specimens and evaluated using SEM. The addition of fiber was found to cause a statistically significant increase in the transverse strength of the injection system's acrylic. In SEM observation it was revealed that there was good adhesion between glass fiber and both acrylic resins. The glass fibers distribution was more even in the injection system's acrylic. It is suggested that injection system's acrylic be fiber-reinforced to reduce denture fractures.
