Repairability of rubber-backed vitrimer composites under variations of impact damage
This study evaluates the effectiveness of rapid heat pressing repair on composites made of vitrimer matrix, a reshapable and recyclable polymer, subjected to varying degrees of impact damage. Two types of composites were fabricated for impact testing: randomly oriented glass fiber reinforced vitrimers (GFRV) and woven carbon fiber reinforced vitrimers (CFRV). Izod pendulum impact tests were conducted on samples along both the thickness and width. Impacts with varying energy levels were applied to induce different degrees of damage, allowing for the assessment of impact strength degradation and repair effectiveness. Additionally, a rubber adhesive layer was applied to the back of composites to quantitatively measure the increase in energy absorption and its effect on repair performance. The findings demonstrate the potential of rapid heat pressing repair in restoring the mechanical integrity of vitrimer composites and highlight the influence of a rubber adhesive layer in enhancing energy absorption and repair efficacy.
期刊介绍:
Composites Communications (Compos. Commun.) is a peer-reviewed journal publishing short communications and letters on the latest advances in composites science and technology. With a rapid review and publication process, its goal is to disseminate new knowledge promptly within the composites community. The journal welcomes manuscripts presenting creative concepts and new findings in design, state-of-the-art approaches in processing, synthesis, characterization, and mechanics modeling. In addition to traditional fiber-/particulate-reinforced engineering composites, it encourages submissions on composites with exceptional physical, mechanical, and fracture properties, as well as those with unique functions and significant application potential. This includes biomimetic and bio-inspired composites for biomedical applications, functional nano-composites for thermal management and energy applications, and composites designed for extreme service environments.
