It was observed that CH2/CONH ratio had a significant influence on various mechanical properties such as tensile strength, elongation to break, fracture toughness, fracture energy and therefore, on the abrasive wear performance.
These processes can degrade engineering significant parameters under both static and cyclic loading, such as fracture toughness, breaking stress and elongation to failure at a critical hydrogen level.
It is just that fragile combination of unguarded sensitivity and ball-breaking toughness that has secured her a very loyal female following.
Factorial design and desirability function were used to investigate the effect of two variables, the ratio of the polymers and the concentration of selected plasticizer on four mechanical responses including tensile strength, elongation at break, toughness and elastic modulus for optimization of the film formulation.
In unmodified composites an increase in Young´s modulus was found with the addition of wood flour to PP, whereas tensile strength, strain at break and fracture toughness were observed to decrease as fibre content increased.
The hybrid hydrogels exhibited excellent tensile and compressive properties with tensile modulus of 51 184 kPa, ultimate tensile stress of 210 540 kPa, tensile elongation to break of 500 600%, fracture toughness of 52 188 J m−2; compressive modulus of 0.40 1.58 MPa, compressive strengths of 10.3 34.5 MPa and compressive strains of 80 85%.
The reinforcement by the CFM resulted in a significant increase in the strain at break, indentation creep, fracture toughness and impact toughness but moderate increase in flexural strength and flexural modulus.
Increasing the starch content led to an increase in modulus and decreases in tensile strength, elongation to break and toughness.
Compared to neat PLA, the Young's modulus, elongation to break, and toughness of PLA/2%HLCNCs were improved by 14, 77, and 30%, respectively.
