The novel low-density microcellular PLA blends demonstrated outstanding mechanical properties such as high strength, high modulus, substantial ductility, and a 14-fold increase in impact resistance as compared to PLA homopolymer.
A substantial increase in modulus values is observed for the nanocomposites almost in all cases, but the complicated character of these dependencies may be seen.
However, in such designs, despite using a low modulus adhesive, substantial load sharing seems to occur only after the adhesive in the hybrid joint has yielded.
Although recent nanoindentation studies have revealed the existence of substantial variations in tissue modulus within single specimens of trabecular bone, little is known regarding the biomechanical effects of such intraspecimen variations.
Optimization of PI concentration or irradiation intensity was particularly important for achieving maximum mechanical properties; a sub-optimal choice of PI concentration or irradiation intensity resulted in a substantial reduction in hydrogel modulus.
In the macroscopic responses, prior transverse direction loading resulted in widening of the reorientation plateau, a reduction of the effective Young's modulus, and substantial alteration of effective Poisson's ratios during axial direction straining.
The inclusion of particular polystyrene-based compatibilizers was observed to have a substantial effect on the modulus of the composite and in some cases this is reflected in the level of preferred orientation in the TLCP.
The substantial increase in storage modulus of the gel filled systems can be attributed to the presence of three-dimensional networks of crosslinked gel which provide greater resistance to dynamic deformation.
However, a substantial decrease in Young's modulus was observed with the increase in loading rate.
Unlike to damping capacity, the dynamic Young's modulus shows no substantial changes after adding CNTs to AlSi SiCp.
