In this study, static coefficients of friction for laminated veneer lumber on steel surfaces were determined experimentally. The focus was on the frictional behaviors at different pressure levels, which were studied in combination with other influencing parameters: fiber orientation, moisture content, and surface roughness. Coefficients of friction were obtained as 0.10–0.30 for a smooth steel surface and as high as 0.80 for a rough steel surface. Pressure influenced the measured coefficients of friction, and lower normal pressures yielded higher coefficients. The influence of fiber angle was observed to be moderate, although clearly detectable, thereby resulting in a higher coefficient of friction when sliding perpendicular rather than parallel to the grain. Moist specimens contained higher coefficients of friction than oven-dry specimens. The results provide realistic values for practical applications, particularly for use as input parameters of numerical simulations where the role of friction is often wrongfully considered.

在这项研究中，通过实验确定了胶合板在钢表面的静摩擦系数。重点是在不同压力水平下的摩擦性能，并结合其他影响参数进行了研究：纤维取向，水分含量和表面粗糙度。对于光滑的钢表面，摩擦系数为0.10–0.30，对于粗糙的钢表面，摩擦系数为0.80。压力影响了测得的摩擦系数，较低的法向压力产生较高的系数。尽管可以清楚地检测到纤维角度的影响，但观察到的影响是中等的，因此在垂直而不是平行于晶粒滑动时会导致较高的摩擦系数。潮湿的样品比干燥的样品具有更高的摩擦系数。
