Table 3.

Flexural modulus mean and standard deviation (GPa) for the interaction between %wt of glass fibers and type of resinous material. Statistical comparisons by ANOVA following Tukey HSD test and paired comparisons by Student t-test (α = 0.05).

Quantity of glass fibers (%wt)	Type of resinous materials
Quantity of glass fibers (%wt)	Filled resin	Unfilled resin
0	2.06 ± 0.88^Ba	1.01 ± 0.71^Cb
10	4.48 ± 3.02^ABa	7.03 ± 7.86^BCa
15	5.69 ± 2.79^Ab	19.33 ± 16.75^ABa
20	6.04 ± 3.39^Ab	15.72 ± 8.03^ABa
30	2.49 ± 1.34^Bb	29.36 ± 13.92^Aa

Different capital letters (vertical analysis) and lower case letters (horizontal analysis) mean statistical significant differences with P < 0.05.
