In a context of sustainable development, a growing number of works relate to the production of composites with bio-based matrices including polylactide (PLA), which has become a major actor in the market which could in the long term serve as an alternative to petroleum-based polyolefins.[1] Among the various composites production processes, Resin Transfer Molding (RTM) is a specific process which relies on the injection, into a mold containing fibers, of a monomer and a catalyst in order to carry out the in situ polymerization of the matrix. The major advantage over conventional melt processes is the possibility of reaching a high amount of fibers while improving their wetting by the matrix. While a wide selection of thermosetting matrix resins are available on the market for RTM process, there are only a few commercial resins for thermoplastic matrices (TP-RTM).[2] Although composites production has been reported with E-caprolactone (E-CL) in TP-RTM,[2] PLLA-matrix composites via this process had never been described. Recent studies carried out at UMET laboratory made it possible to obtain the first PLLA/glass fiber composites prototypes.[3a] We present here current work aiming at strengthening the mechanical properties of the PLLA matrix by producing a novel composites family by copolymerization of L-LA with E-caprolactone (PLCL), with various reinforcements.[3b] PLCL/glass fabric prototype with 30 % E-CL displays an impact resistance 87% higher than pure PLLA analog.
