In this study, PLLA-based/glass fabric composites with poly(L-lactide-co-e-caprolactone) as the matrix were reported, displaying high wettability and toughness.
Poly(L-lactide) (PLLA) is a semicrystalline biopolymer of great interest due to its biosourced, biocompatible, and compostable nature. However, its brittleness prevents its use in a wide range of applications. In order to reinforce PLLA, it is often used in polymer blends or in composites. In this contribution, an unprecedented family of PLLA-based/glass fabric composites with poly(L-lactide-co-e-caprolactone) statistical copolymers as the matrix are reported. These biocomposites were produced in a one-step synthesis by in situ copolymerization of L-lactide and e- caprolactone in the thermoplastic resin transfer molding (TPRTM) process. These materials display high matrix/fabric wettability along with strong rubbery character.
