| Summary: | Aim: The aim of this in vitro study was to compare the flexural
strength, the flexural modulus and compressive strength of the
acrylic polymer reinforced with glass, carbon, polyethylene and
Kevlar fibres with that of plain unfilled resin.
Materials and Methods: A total of 50 specimens were prepared
and divided into 10 specimens each under 5 groups namely group
1- control group without any fibres, group 2 – carbon fibres, group
3- glass fibres, group 4 – polyethylene, group 5- Kevlar. Universal
testing machine (Tinius olsen, USA) was used for the testing of
these specimens. Out of each group, 5 specimens were randomly
selected and testing was done for flexural strength using a three
point deflection test and three point bending test for compressive
strength and the modulus was plotted using a graphical method.
Statistical analysis was done using statistical software.
Results: The respective mean values for samples in regard to their
flexural strength for PMMA plain, PMMA+ glass fibre, PMMA+
carbon, PMMA+ polyethylene and PMMA+ Kevlar were 90.64,
100.79, 102.58, 94.13 and 96.43 respectively. Scheffes post hoc
test clearly indicated that only mean flexural strength values of
PMMA + Carbon, has the highest mean value. One-way ANOVA
revealed a non-significant difference among the groups in regard
to their compressive strength.
Conclusion: The study concludes that carbon fibre reinforced
samples has the greatest flexural strength and greatest flexural
modulus, however the compressive strength remains unchanged. |
