采用糙皮侧耳真菌的菌丝体来替代传统的化学粘合剂来粘结废棉纤维并通过一定的后加工处理制备质轻环保的废棉纤维生物复合板材，并通过添加废旧烟梗和烟叶作为骨架材料来增强其压缩强度。实验结果表明，添加了不同骨架材料的棉纤维生物复合板抗压载荷和压缩弹性模量都优于废棉纤维生物复合板；厚度为20 mm的废棉纤维生物复合板在合理的压缩范围内的抗压载荷达到12.35 kN，而添加了烟叶和烟梗的废棉纤维生物复合板的抗压载荷分别达到了10.16 kN和27.10 kN；最终制成的三种不同的生物复合材料其压缩弹性模量最高达到22.40 MPa，赋予了该生物复合材料特殊的静态压缩特性。%Light and green waste cotton fibers bio-composites were prepared by the use of the mycelium of pleurotus ostreatus to intertwine the waste cotton fibers instead of the traditional chemical adhesives and then certain post processing,and improving its compressive strength by adding waste tobacco leaves and stems as the skeletal materials. The results show that the compressive load and compression modulus of the waste cotton fiber bio-composite panels added with different skeletal materials are better than cotton fiber bio-composite panels. The compressive load of the waste cotton fibers bio-composite panels with the thickness of 20 mm reach 12.35 kN in the reasonable compression range, and the compressive load of the two materials by adding tobacco leaves and stems are up to 10.16 kN and 27.10 kN respectively. The most high compression modulus of the final three different biological composites is 22.40 MPa,which lead to the special static compression characteristics of the materials.
