The deformation model of the prepregs made of plain and multi-axial textiles is presented. The function dependences for the strain determination during transversal compression of each thread family are found. The characteristics in form of inelastic constant of the compression and modulus of elasticity during compression are determined. The methods of these characteristics acquisition are developed. The correspondent experiments conducted for T-13 textile and the mentioned characteristics were found.
