The influence of barometric hydrolysis on the glass-transition temperature of oak timber

Temperature dependences of the dynamic shearing modulus of oak timber Quercus robur subjected to hydrolysis were obtained by dynamic mechanical analysis. A decrease of the timber dynamic shearing modulus and considerable reduction of the glass-transition temperature of its amorphous components compl...

Description
Summary:Temperature dependences of the dynamic shearing modulus of oak timber Quercus robur subjected to hydrolysis were obtained by dynamic mechanical analysis. A decrease of the timber dynamic shearing modulus and considerable reduction of the glass-transition temperature of its amorphous components complex with an increase of the hydrolysis hardness level were revealed. Suppositions about the nature of the found effects were made.
