Manufacturing and mechanical characterization of natural fibre reinforced biocomposites: application in a small wind turbine

In this work, new biocomposites were manufactured and mechanically tested. A resin from natural resources (SuperSap®) was reinforced by a bidirectional flax and oak wood laminates. Normalized tensile and three-point bending tests were performed and it was observed that the oak wood laminates in the...
