Abstract: The percolation threshold of electrically conductive function was studied by mixing adhesive elements with conductive elements and then laminating with wood elements together to form wood-based composite panels. The results showed that the threshold values were about 8%~14%, and the spreading content and filling content were correspondingly about 14%~25%and 12%~20%, respectively. The uniformity of conductive function was better once the percolation phenomena occurred. Additionally, some mechanism and numerical relationship should be further researched.
