Spatial mapping of both indentation hardness and modulus reveal complex long-range softening patterns that are indicative of internal stress fields along the shear band.
FEM models created from micro-CT images reveal that modulus approaches an asymptotic value with increasing diameter, and demonstrate an architecture-dependent drop in modulus at decreasing diameters.
Results from mechanical testing revealed that modulus and strength improved up to 6 wt.% clay loading while elongation and toughness of nanocomposites increased with the addition of 2 wt.% clay content in the matrix.
DMA results revealed that storage modulus and loss modulus values of composites increased with increasing CF content.
The results revealed that the modulus of rupture and modulus of elasticity of BFRPCs increased with increasing bamboo fiber loading up to 60 wt% and then declined sharply as the fiber increased further.
AFM-nanoindentation showed a decrease in modulus from 1.5 GPa to 50 MPa during acid etching of individual collagen fibrils and revealed that the modulus profile followed the axial periodicity.
The data revealed that bending modulus decreased with structural expansion.
DMA and contact angle analysis revealed that the modulus and hydrophobicity increased with increase in crosslinking.
The simulated high elastic constants, modulus, hardness and ideal strength reveal that BC7 exhibits excellent mechanical characters and belongs to a superhard material with prospects for potential multi-functional material in electronic and mechanical application.
TPO/PP-g-MA/MMT nanocomposites prepared by Kim et al. (2007a, 2007b) revealed that the modulus and yield strength enhanced by increasing PP-g-MA/organoclay ratios.
