Dimensional change of acrylic resin plate after the reinforcement of glass fibre

<span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>The effect of fibre reinforcement of polymethyl methacrylate was investigated. Glass fibres have been studied as strengthening </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>material added to polymethyl methacrylate. The purpose of this study was to evaluate dimensional change of acrylic resin plate after </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>glass fibre reinforcement. As a research subject is an acrylic resin plate of 65 </em><span style="font-size: 10pt; color: #231f20; font-style: normal; font-variant: normal;"><em>× </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>10 </em><span style="font-size: 10pt; color: #231f20; font-style: normal; font-variant: normal;"><em>× </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>2.5 mm with the number of 32 samples were </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>distributed randomly in 4 experimental groups. Each group consisted of 8 samples and control groups.

Control </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>group which was not given treatment. Dimensional change was measured by profile projector. The data was analyzed by One-Way </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>ANOVA and LSD test showed that there was significant difference in dimensional change (p &lt; 0.005).
