The present investigation outlines the significant improvement of tensile strength, scratch hardness, thermostability, water vapor permeability, and adhesive strength without much influencing impact resistance, bending, and elongation at break of the nanocomposites compared to pristine HBPU thermoset.
The addition of more than Vf of 1.0% steel fibers resulted in the significant improvement of flexural strength, deflection capacity, and post-peak ductility, while the increase of compressive strength led to an increase in the flexural strength and a decrease in the post-peak ductility.
The nanometer pore structure resulted in significant improvement of compressive strength and thermal insulation properties of the carbon foams.
Based on the depth of shade values, it was found that by increasing chitosan nanoparticles concentration up to 0.3% (w/v), there was significant improvement of color strength.
It accelerates the hydration reaction resulting in a significant improvement of compressive strength of high volume fly ash (HVFA) concrete (Barbhuiya et al. 2009; Jayakumar and Abdullahi 2011).
Quality analysis showed that the introgression of 1Dx2s and 1Dx2f subunits led to significant improvement of dough strength and breadmaking quality.
Interfacial Al4C3 on partially reacted CNTs led to significant improvement of interfacial strength and consequent enhancement of load transfer efficiency in AMCs, compared to those composites without carbide.
Experimental results presented in this paper show that a significant improvement of the strength capacity, deformation capacity and ductility of columns can result of the CFRP application, but the observed gains strongly depend on the reinforcement systems.
The results show that the training resulted in a significant improvement of the strength and endurance of the paralyzed lower leg muscles, and in an increased ROM of the ankle joints.
The use of a nail plate is found to be effective in reinforcing the timber and in increasing the stiffness of STC lap joints with coach screws, but they did not produce a significant improvement of their strength.
