Figure 2. Composite flexural strength. Heat-cured nano DCPA composite: •. Chemically cured nano DCPA composite with HEMA:  . Chemically cured nano DCPA composite without HEMA:  . Specimens (A) without immersion, (B) after 1 day’s immersion, and (C) after 56 days’ immersion. Each value is the mean of 5 measurements, with the error bar showing 1 standard deviation (SD) (mean ± SD; n = 5). Two-way ANOVA identified significant effects of resin composition and DCPA:whisker ratio (p < 0.05), with no significant interaction between the two factors (p = 0.86). The 56-day immersion decreased the strength of the chemically cured DCPA-whisker composites, but not the heat-cured DCPA-whisker composites and the controls (p > 0.1).
