Tensile behavior of environmental pollutant crumb rubber filled epoxy composites

Tensile test is conducted on environmentally pollutant crumb rubber/epoxy composite. Crumb rubber particles with different volume fractions (10, 20 and 30%) are reinforced with epoxy matrix. Stress-strain curves reveal brittle fail for all the samples. Crumb rubber filled epoxy composites reveal higher modulus (13%-28%) and strength (28%-44%) than neat epoxy sample. Epoxy with 30 volume % of crumb rubber depicts higher modulus and strength compared with all other compositions, exemplifying use of crumb rubber for utilarian applications. Crumb rubber/epoxy composites register higher specific modulus and strength for all compositions in comparison with neat epoxy. Scanning electron micrographs of test samples are used to analyze property - composition correlations. Finally, property map is plotted to compare the results of present study with existing ones to highlight the efficacy of the proposed composites.

Automated summary

The tensile test conducted on crumb rubber/epoxy composite showed that the composite with crumb rubber has higher modulus and strength compared to the neat epoxy sample. Among all compositions, epoxy with 30% crumb rubber exhibited the highest modulus and strength, demonstrating its potential for utilitarian applications.
