Comparison of composites made of F. fomentarius and hemp shives with different approved construction materials that are most frequently used in Germany. A Ashby diagram highlighting elasticity as a function of density. Dots correspond to the values obtained in this study or published earlier [10]. Black, uncompressed composites this study; yellow, uncompressed composites [10]; orange, 10 mm compressed composites; blue, 5 mm compressed composites. B Radar chart representing standardized values for different materials. The higher the value the better the performance on a scale between 0 and 100%. Raw data used for standardization were taken from this study and from data sheets of industrially used materials (Additional file 1: Fig S4)
