Mechanical properties (in compression) of neat resins and monodisperse, non-silanized silica-filled composites

	TEGDMA (with 0.5 wt% DMAEMA)	TEGDMA (no DMAEMA)	Non-ordered Composite (with 0.5 wt% DMAEMA)	Ordered Composite (no DMAEMA)
Modulus (GPa)	1.91 (0.11)	1.88 (0.24)	4.92 (0.30)	4.49 (0.48)
Failure Strain (%)	29 (2.9)	29 (4.7)	8.3 (1.2)	14.2 (2.5)
Compressive Strength (MPa)	198.9 (26.7)	220.7 (56.3)	165.4 (21.2)	192.1 (17.2)
Toughness^* (J/m³ × 10⁷)	3.12 (0.65)	3.05 (0.86)	0.77 (0.31)	1.81 (0.48)

Toughness was calculated as the integrated area under the stress-strain curve[19].
