Non-Destructive Evaluation (NDE) of natural fiber based composite with PLA/PBAT matrix for industrial applications

In this work, thermoplastic composite materials, potentially usable for applications in the transport field, have been prepared starting from a commercial PLA/PBAT blend including calcium carbonate as a filler and a commercial jute fiber fabric. Specimens of adequate size cut from hot pressed plates and subjected to flexural tests were systematically analyzer with the aid of an optical non-destructive technique to highlight the dissipative mechanisms induced by the test and responsible for the failure of the material. The NDE technique adopted belongs to the optical methods in full-field and non-contact modality.
