Project description

The fiber-reinforced polymer composites are valued for their high strength/stiffness-to-weight ratios, making them indispensable in sectors such as construction, transport, and energy. However, their reliance on fossil-derived thermosets and the lack of viable recycling pathways pose significant challenges in terms of cost, safety, and environmental impact. To address these limitations, this project focuses on the development of composites with recyclable epoxy resin systems with added functionality, such as fire retardancy and environmental durability. Unlike traditional epoxies, which are difficult to reclaim, recyclable epoxies offer the potential for closed-loop composite systems, enabling material recovery and reuse without compromising mechanical performance.

These bio-based resins are expected not only to reduce carbon footprint but also to make use of underutilized biomass, which is often burned for energy. By repurposing these resources into functional composite matrices, the project contributes to both resource efficiency and industrial decarbonization.

To further enhance durability and reduce maintenance costs, the project integrates other bio-based additives, such as lignin and various organic acids and amines, to add other functionality to the polymer matrix.
