利用灵芝菌丝体与果树、杨榆和竹材3种碎料，分别制备木竹碎料/菌丝体原位成型材料。结果表明：果树碎料更适合灵芝菌丝体的生长。3种材料的2 h吸水厚度膨胀率介于3.71%~9.56%之间，24 h吸水厚度膨胀率介于8.82%~13.29%之间。在10%压缩变形时，果树碎料/菌丝体原位成型材料（GG）的压缩强度最大，其最终质量剩余率最大（35.56%），最大质量损失率较小（0.57%），热稳定性较好。果树碎料/菌丝体原位成型材料的导热系数＜0.093 W/（m·K），保温性能与常用保温建筑材料性能相当。果树碎料/菌丝体原位成型材料具有较好的压缩强度、热稳定性和保温性能。
In-situ molding composites made of wood/bamboo splinter (fruit tree wood, poplar, elm, and bamboo) and,Ganoderma,lucidum, mycelium were studied. The results showed that the fruit tree wood splinter was suitable for the mycelium growth. The thickness swelling rate of water absorption of different type composites at 2 h and 24 h were 3.71%~9.56% and 8.82%~13.29%. The compressive strength of fruit tree wood splinter/mycelium in-situ molding composite (GG composite) was the highest value at 10% deformation. The final mass residual rate of GG composite was 35.56% after the thermogravimetric test, the maximum loss rate was at minimum(0.57%), GG composite showed good thermostability. The thermal conductivity of the GG composite was less than 0.093 W/(m·K), which thermal insulation performance was similar to that of the commonly used thermal insulation materials in the building industry. GG composite display good compressive strength, thermostability, and thermal insulation performance.
