Mechanical properties of ABS specimens such as elasticity module, tensile strength and tensile strain at yield, tensile strain at break, flexural modules and izod impact strength (notched) were measured by using some test methods.
Mechanical properties include their tensile strength at yield, elongation at yield, and tensile modulus.
Some synergism has been observed in the PE/SBR composition dependence of the tensile strengths at yield and break.
Tensile strength at yield for raw and JB oil treated fibres are 318 and 418 MPa respectively.
With respect to mechanical properties, the results showed that modulus of elasticity and tensile strength at yield are affected by PLA content.
A significant increase in the tensile modulus and stress at yield and a decrease in strain at yield were observed for both aging temperatures.
Thus, the elongation at break (expressed as a percentage) appears to be a more sensitive 'index' of degradation than the tensile strength, the stress at yield or the modulus of elasticity.
The effect of these variables on tensile strength, Young's modulus, elongation at yield and flexural strength was determined through a 22·31 factorial design.
As in normal rigid-plastic analysis, concrete acts only when compressed, and then at its compressive strength, and steel acts at its tensile yield strength whilst it remains intact.
Annealing of the samples (75 °C for 45 days; 120 °C for 3 h) did not markedly affect the tensile modulus, yield stress, and stress at break of the blends.
Blends made in the twin screw extruder consistently showed better dispersion and mechanical properties: higher tensile modulus, yield strength and elongation at break; higher notched Izod impact strength and lower ductile-brittle temperature.
