Abstract. The article considers the tribological features of the interaction between inner-layer materials of cranial orthoses and the skin of infants. The relevance of the study is determined by the fact that the effectiveness of cranial deformity correction depends not only on the geometry of the device and the magnitude of corrective action, but also on the properties of the materials that remain in prolonged contact with the child’s scalp. Insufficient tangential resistance in the contact zone may contribute to displacement of the device, whereas increased friction during long-term wear requires assessment in terms of possible growth of shear stresses in the superficial layers of the skin.

The aim of the study was to compare the static coefficient of friction between cranial orthosis inner-layer materials and a skin model. Cotton knitted fabric and Plastazote, a foamed polyethylene material used in modern cranial orthoses, were selected as the materials under study. Fresh pig skin was used as a model of the skin surface. The coefficient of friction was determined by the inclined plane method based on the angle at which sliding of the contacting surfaces began.

The results show that cotton knitted fabric maintains high resistance to initial displacement under both dry and moist conditions.

The obtained results confirm the potential of using cotton knitted fabric as an inner-layer material for a hybrid cranial orthosis in order to improve positional stability of the device. At the same time, the effect of prolonged moistening on the nature of material-skin contact requires further investigation, since changes in moisture conditions may be accompanied by softening of the superficial skin layers, an increase in the actual contact area, and enhancement of the adhesive component of friction.
