Internal friction measurements give many informations concerning the properties of solids in relation to their microstructure. Under some conditions, the value of damping may be very important. In this paper, a torsional pendulum apparatus able to measure internal friction in a large range of values is described. Some applications to the study of ice near the melting point and water based composite materials (such as water mixtures used in cryobiology) are presented Description de l'appareillage de mesure precise automatique de valeurs de frottement interne comprises entre 10 −3 a 0,5 (en decrement logarithmique. Application au melange eau-ethyleneglycol cristallises, en fonction du traitement thermique
