The addition of polymer modified nanoclay (PMN) into the control asphalt binder decreases the complex shear modulus, and enhances the resistance to fatigue cracking.
The origin of such behavior is attributed to: (a) reduction of driving forces due to continually degrading composite elastic modulus and (b) enhanced damage impedance originating from resistive tractions due to pervasive fiber bridging and pullout in the wake.
The results indicated that as the silica content increased to 50 wt%, the ultimate tensile strength and modulus were enhanced to 191% and 614%, respectively.
Besides, tensile strength and Young's modulus are enhanced by 37% and 820%, respectively.
The nanohardness and Young's modulus are enhanced 2 4× to 1.5 GPa and ∼300 GPa, respectively.
Many nanocomposites have their thermal properties increased at 20°C 100°C compared to the pure matrix, the barrier properties to gas are lowered from one-third to one-sixth, and the modulus is enhanced 2 10 times compared to the pure polymer matrix.
Specifically, compared with PE and R-PE samples, the yield strength increased by 137.7% and 79.0%, and Young's modulus enhanced by 160.6% and 109.6%.
Varying the sheath-to-core flow rate ratios from 40 5 to 10 5, the tensile stress at break, the tensile strain at break, and the Young׳s modulus were enhanced from 24.51 MPa to 77.07 MPa, 567% to 1420%, and 247.25 MPa to 539.70 MPa, respectively.
For GAIM HDPE/PC microfibril composites, its yield strength is increased by 68%and66%6%, compared to the GAIM HDPE parts and the common injection molded (CIM) HDPE/PC composites, respectively; meanwhile, the Young's modulus is enhanced by 253% and 17%, compared to the GAIM HDPE parts and the CIM HDPE/PC composites, respectively.
