This paper presents the results of several experimental analyses performed on a biobased sandwich structure. The material studied is made up of thermoplastic skins reinforced by flax fibres and applied to a balsa core. It is produced by a single-stepliquid resin infusion process. First, the skin–core interfacial properties were measured and compared with those of the existing materials. Then, several quasi-static and dynamic analyses were performed to study the flexural behaviour of sandwich beams. The elastic and ultimate properties of the skins and core were deduced from these flexural tests. In addition, a failure mode map was developed based on the existing theories to explain the failure modes observed under different boundary conditions.The influence of the statistical spread of the core’s mechanical properties on the failure of sandwich beams was considered. Moreover, fatigue analyses were conducted to determine the fatigue resistance of this bio-based structure. Its behaviourwas compared with that of the previously tested non-bio-based sandwich beams.Read less <
