本研究探讨了编织玻璃纤维的位置和数量对增强义齿基托树脂的弯曲强度，弯曲模量和韧性的影响。织造玻璃纤维由1-4个层压板组成。采用化学固化法对三种类型的4 mm厚的试样进行固化：压缩纤维、中心纤维和拉伸纤维。未加固的标本作为对照。进行三点弯曲试验，并在烧制编织玻璃纤维后计算编织玻璃纤维含量。当编织玻璃纤维在张力下结合在基础树脂外部时，获得最佳结果，从而增加弯曲强度和弯曲模量。此外，通过增加在张力下结合到部分中的编织玻璃纤维的数量，使用编织玻璃纤维增强的义齿基托树脂更坚韧。
This study examined the effects of the position and the number of woven glass fibers on the flexural strength, flexural modulus, and toughness of reinforced denture base resin. The woven glass fiber consisted of 1-4 laminated sheets. Chemical curing was used to polymerize three types of 4-mm-thick test specimens: fibers in compresrion, fibers in the center, and fibers in tension. Unreinforced specimens were produced as controls. A three-point flexural test was performed and the woven glass fiber content was calculated after the woven glass fiber was fired. The best results were obtained when the woven glass fiber was incorporated outside the base resin under tension, thereby increasing the flexural strength and flexural modulus. Furthermore, the denture base resin reinforced with woven glass fiber was made tougher by increasing the number of woven glass fibers incorporated into the portion under tension.
