Development of biobased epoxy matrices for the preparation of green composite materials for civil engineering applications
Epoxy matrices are successfully used for structural strengthening in civil engineering applications by means of carbon fiber reinforced polymers (CFRPs). In the context of sustainable development, the aim of this study is to develop biobased epoxy matrices as an alternative to the traditional petroleum-based epoxy matrices used in CFRPs. This study focuses on two biobased epoxy monomers: a diglycidyl ether of bisphenol A (DGEBA) and a sorbitol polyglycidyl ether (SPGE). These monomers are reacted with a biobased curing agent, a phenalkamine (PhA), derived from cardanol. After in-depth characterization of the chemical structures of the three monomers, the reactivity of both systems, DGEBA-PhA and SPGE-PhA, is studied using differential scanning calorimetry and rheology. The properties of the networks are characterized via dynamic mechanical analysis and water uptake measurements for polymers with partial or full conversion of epoxy groups, which are obtained by crosslinking at room temperature or at high temperature, respectively. The results reveal that the two systems are good candidates for the preparation of green composite materials as they meet the requirements necessary for manufacturing composites in civil engineering applications.

These monomers are reacted with a biobased curing agent, a phenalkamine (PhA), derived from cardanol. After in-depth characterization of the chemical structures of the three monomers, the reactivity of both systems, DGEBA-PhA and SPGE-PhA, is studied using differential scanning calorimetry and rheology.
