Investigation of the Static and Dynamic Behavior of a 3D-Printed PFF Sandwich Composite with Conventional Honeycomb and Auxetic core
Résumé
The environmental problems demanded to use bio-material in several industrial applications. In this case, the use of biological material in composite structure have been increased in this century. The main idea of this research is to use a bio-based material in sandwich composite structure dedicated to transport industrial applications. Also, auxetic structures have presented a good mechanical property such as higher stiffness, strength, and energy absorption. This study presents an experimental analysis of the static and dynamic properties of a bio-sandwich composite with conventional honeycomb and auxetic core. An additive manufacturing technique is used to produce the sandwich composites. Static tensile, static and fatigue three-point bending and vibration tests were used to characterize the tested sandwiches. The effect of the bio-based material, the number of cells in the core as well as the core topology are
