Poly( l -lactide- co -ε-caprolactone) Matrix Composites Produced in One Step by In Situ Polymerization in TP-RTM
Résumé
Poly(L-Lactide) (PLLA) is a semi-crystalline 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 fabrics composites with poly(L-lactide-co--caprolactone) statistical copolymers as the matrix is reported. These biocomposites were produced in one step synthesis by in situ copolymerization of L-lactide and -caprolactone in Thermoplastic Resin Transfer Molding (TP-RTM) process. These materials display high matrix/fabrics wettability along with strong rubbery character.
