Comprehensive Review on Eco-Friendly Fillers 2012–2023: A Potential Resource for Polymer Composites

Low-cost, naturally derived, recycled materials have been under the spotlight recently because of their potential use as fillers in composites and other products. With varied amounts and types of fillers, polymer composites electrical and mechanical characteristics may be tailored to be inexpensive, environmentally friendly, or sophisticated. In several applications, including the construction and design sectors, as well as the automotive, aviation, and shipping industries, polymer-based composites with the right filler materials have been created and are successfully employed. This review article provides details on the main groups of naturally occurring fibres, with a focus on their uses. Here, we explore successful natural fillers documented in the last 10 years. It also offers an overview of the key features of polymer technology for creating hybrid composites that are both practical and environmentally beneficial.
