Relative elongation at break

GPa) and the relative elongation at break (%). The first of the indices characterizes the resistance of the fiber to deformation under the affect of the acting force and determines the value of the tensile strength causing the formation of the unitary relative elongation (e). The modulus E characterizes the susceptibility of the fiber to deform based on the principle of inverse proportionality. The other parameter, i.e., 6, characterizes the maximum ability of the fiber to deform under the effect of the acting tensile force.

The results presented in the table show that additives of powders of silicon raise meehanical characteristics of films, and the effect of improvement of mechanical properties is more expressed in case of composite PE + 0.5% ncSi-97 at which in comparison with pure polyethylene relative elongation-at-break has esserrtially grown.

Figure 4.90 displays two examples of the retention of tensile stress and elongation at break (relative to the properties at 20°C) versus temperature for an ETFE. 

Of prime interest are the tensile properties summarized in Table 4, and typical of stress-strain curves exhibited by thermoplastic elastomers. The elongation and strength at break were measured above 1000% and 50 MPA, respectively. Both the tensile modulus and the stress at yield increased by increasing the PCL relative content whereas, as expected, the ultimate elongation at break slightly decreased. 

As shown in Figure 5, the overall elongation at break exhibited a maximum at a concentration of 20% PMMA. At higher concentrations of PMMA, the relative contribution of plastic (irreversible) deformation increased with increasing PMMA content, while that of elastic (reversible) deformation decreased. 

Copolymer test specimens were prepared by pressing slabs for 0.5-3 min at temperatures approximately 20°C above the copolymer melting point, followed by cooling under pressure to room temperature in 5-10 min. Test samples were conditioned at 24°C and 50% relative humidity for at least 48 hr before testing. Stress-strain and tear-strength measurements were made on 0.6 to 0.8-mm-thick specimens. Thicker specimens yield lower values for tensile strength and elongation at break. The test methods used were ...
