FIG. 9. — Mechanical properties of silicone infiltrated structures. (a) Effect of particle size versus tensile strength. (b) Effect of polymer coating ratio versus tensile strength. (c) Silane treatment effect on tensile strength and elongation at break. Improvements in tensile strength and elongation at break were observed with a decreasing particle size. Increases in the polymer coating ratio hindered the elongation at break and the tensile strength of the samples tested. The silane treatment enhanced the tensile strength and elongation at break of the samples when compared with the control group. The 35% HMDS group showed the best results, showing improvement over the results of the silane+B98 samples (n = 4; mean ± SD; *p < 0.1). (d) Effect of particle size versus 100% tensile modulus. (e) Effect of polymer coating ratio versus 100% tensile modulus. (f) Silane treatment effect on 100% tensile modulus. The 100% tensile modulus was decreased in samples with larger particle sizes and smaller polymer ratio coating conditions. There was no significant difference observed in the tensile modulus in the silane and additive conditions (n = 4; mean ± SD; *p < 0.1). HMDS, hexamethyldisiloxane. Color images are available online.
