Natural fiber composites, or biocomposites, have recently gained muchattention due to their low cost, environmental friendliness, and theirpotential to compete with glass-fiber composites. The reported studydemonstrates that biocomposites can be used for load-bearing componentsby improving their structural efficiency through cellular materialarrangements. Laboratory-scale periodic cellular beams and plates weremade from industrial hemp and flax fibers with unsaturated polyesterresin. Material and structural performance was experimentally assessedand compared with results from short-fiber composite micro-mechanicsmodels and sandwich analyses. Short-term analytical evaluation offull-scale cellular biocomposite components indicates that they cancompete with components made from conventional materials. (C) 2004Elsevier Ltd.
