Modeling and statistical understanding: The effect of carbon nanotube on mechanical properties of recycled polycaprolactone/epoxy composites

Recycling of polymer composites has been explored in an attempt to reutilize materials. Several efforts have opted to address this subject from many perspectives including mechanical, chemical, and thermal recycling. Others have also delved into the self-healing materials to remedy this dilemma. However, few studies have delved into understanding the role of carbon nanotube (CNT) in self-healing based recycled polymer composites. Therefore, in this study, experimental and simulation tools were utilized to understand the recycling process when CNTs were incorporated within recycled polycaprolactone/epoxy composites. A polynomial regression model, as a facile approach, was established to simulate the process-property relationship, which is essential for the successful implementation of the future of manufacturing. It found that, by adding CNTs, a reduction in the determined degree of crystallization was induced which correlated with the obtained reduction in the modulus and toughness. Strategies for enhancing mechanical properties have been pointed out for future endeavors.
