Abstract
In the present study, we recycled waste carpet using a vacuum-assisted resin transfer molding (VARTM) process. Three different variations of carpet composites were fabricated, namely, neat epoxy, clay-coated, and clay-infused carpet composites. The carpet composite samples were degraded hygrothermally as well as under a cyclic UV condensation condition. Presence of clay was shown to impede the moisture absorption and UV degradation in the carpet composites. Flexural properties also showed that the presence of clay slows the degradation process of the composites. The flame retardancy result indicated that the presence of clay in the polymer network decreases the ignition time of the carpet composites.

Summary
Carpet waste is both an environmental and economic problem because of the costs involved in the disposal of waste carpet. Recycling of carpet as a structural composite serves as a motivation to address the problem of recycling waste carpet [1,2,3,4]. Recycling can be done either by depolymerization, separation of a part, melt blending, or energy recovery. These recycling techniques are pervasive, time-consuming, and economically infeasible. This results in limited recycling, and improvement in the recycling process is required [1,2]
