Hardness and deformation of particle board at negative temperatures

Abstract

The paper discusses the dependence of hardness, temporary and permanent deformations of the elastic compressed wood, the criterion of the relative convergence of the friction surfaces of the temperature, allowing adjusting the estimates of reliability and availability of bear-ings compressed wood at low temperatures. Results of submissions accurately indicate that at low temperatures hardness and elastic deformation of compressed wood increases, and temporary and permanent deformations and criterion of relative approach of the pair of friction surfaces of metal timber decrease.
