Abstract
Honeycomb sandwich panels are a class of structural composites, made of thin layers molded in hexagonal cells shape that fits the face planes with perpendicular oriented axes, normally the honeycomb material is an aluminum alloy or aramid polymer. Bamboo is considered a sustainable material because it is renewable, absorbs carbon dioxide and uses solar energy, being easily incorporated into nature at its life cycle end. The aim of this paper was to perform mechanical characterization of a honeycomb composite panel, made from sections of mature bamboo culms, using the species Phyllostachys Aurea, fiberglass, synthetic thermoset structural epoxy resin and polyurethane resin derived from castor oil, Ricinus Communis. Subsequently the sandwich panels production, samples were selected for the material mechanical characterization. Flexural and compression tests were performed following the ASTM D7249 and ASTM C365 standards. The flexural tests revealed that main mode of fracture was face buckling following by brittle rupture of the top face sheet and the compressive tests values indicate that honeycomb bamboo panels have good properties when comparing with similar composites.
