ABSTRACT
<p><b>OBJECTIVE</b>To investigate if the Ribbond polyethylene fiber has the effect of reinforcing polymethyl methacylate.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>The flexural strength of chemical-cured PMMA group was (51.383 +/- 2.761) MPa, the flexural modulus was (1791.2 +/- 113.760) MPa; The flexural strength of stainless steel wire reinforced group was (58.725 +/- 1.218) MPa, the flexural modulus was (2092.76 +/- 120.28) MPa; The flexural strength of Ribbond polyethylene fiber reinforced group was (80.975 +/- 2.58) MPa, the flexural modulus was (2866.53 +/- 107.51) MPa. The one-way analysis of variance showed that the results were significant (P < 0.001). Newman-Keuls method showed that the differences among all groups were significant (P < 0.05).</p><p><b>CONCLUSION</b>The Ribbond polyethylene fiber can raise the flexural strength and flexural modulu of polymethyl methacylate.</p>
