摘要：
Bending strength of different wood-based panels such as particleboard, MDF and OSB has been studied at temperatures between +20degreesC and +140degreesC. It was found that the temperature for all studied panels significantly affects bending strength. After one-hour effect of the temperature 140degreesS the bending strength of panels is reduced (in comparison to the temperature of 20degreesC) by 40% for particleboard, by 37% for MDF and by 30% for OSB. The results of the present study indicate that it is important to consider the temperature effects in application of wood-based panels.
