中文摘要
目的 观察聚乙烯纤维对聚甲基丙烯酸甲酯是否有加强作用。方法 采用自制模具,制作化学固化聚甲基丙烯酸甲酯(PMMA)组、化学固化PMMA加0·25 mm结扎丝组、化学固化PMMA加Ribbond聚乙烯纤维组3组试样,共28个。用万能材料实验机进行三点弯曲实验,记录试样的弯曲强度和弹性模量值,并进行统计分析。结果 化学固化PMMA组的弯曲强度为(51·383±2·761)MPa,弹性模量为(179 1·2±113·760)MPa。化学固化PMMA加 0·25 mm结扎丝组的弯曲强度为(58·725±1·218)MPa,弹性模量为(209 2·76±120·280)MPa。Ribbond聚乙烯纤维加强组的弯曲强度为(80·975±2·580)MPa,弹性模量为(286 6·53±107·510)MPa。经单因素方差分析各组之间皆有显著性差异(P
英文摘要
Objective To investigate if the Ribbond polyethylene fiber has the effect of reinforcing polymethyl methacylate. Methods 28 specimens were fabricated and divided into 3 groups : group of chemical-cured PMMA, group of chemical-cured PMMA reinforced by stainless steel wire and group of chemical-cured PMMA reinforced by Ribbond polyethylene fiber. A three- point bending test was used to measure the flexural strength and flexural modulus of specimens. Then the data were analyzed with a one-way analysis of variance.Results The flexural strength of chemical-cured PMMA group was (51·383±2·761) MPa,the flexuralmodulus was (179 1·2±113·760) MPa; The flexural strength of stainless steel wire reinforced group was (58·725± 1·218) MPa, the flexural modulus was (209 2·76±120·28) MPa; The flexural strength of Ribbond polyethylene fiber reinforced group was (80·975±2·58) MPa,the flexural modulus was (286 6·53±107·51) MPa。The one-way analysis of variance showed that the resultswere significant (P
