目的。本研究研究了玻璃纤维强度定量百分比对丙烯酸树脂横向强度、最大变形和弹性模量的不同影响。材料与方法。五十四个样品在专门设计的模具中成型，以根据制造商的建议生产相同的样品。研究了六百分比的松散随机形式的玻璃纤维增强材料。每种玻璃纤维处理百分比（0%、1%、2%、5%、10%、15%）与粉末/液体总质量相关。结果。结果表明，1%玻璃纤维处理提高了测试样品的横向强度。发现测试的治疗组中失效时的最大变形是不同的。玻璃纤维浓度对断裂强度和变形的交互作用显着（p < 0.0001）。结论。研究发现，1% 的玻璃纤维浓度可提供最佳的断裂强度和变形结果。发现显着较高的玻璃纤维百分比会削弱树脂。
Purpose. This study investigated the different effects of quantitative percentages of glass fiber intensity on the transverse strength, maximum deformation, and the modulus of elasticity of acrylic resin.Materials and methods. Fifty-four specimens were formed in a specially designed mold to produce identical specimens in accordance with the manufacturer's recommendations. Six percentages of glass fiber reinforcement in loose random form were studied. Each glass fiber treatment percentage (0%, 1%, 2%, 5%, 10%, 15%) was related to the total powder/liquid mass.Results. The results indicated that 1% glass fiber treatment enhanced the transverse strength of the tested specimen. Maximum deformation at failure in the tested treatment groups was found to be different. The interaction of glass fiber concentration on fracture strength and deformation was significant (p < 0.0001).Conclusion. The 1% glass fiber concentration was found to give the best fracture strength and deformation results. Significantly higher glass fiber percentages was found to weaken the resin.
