This paper presents the developed probabilistic spatial model fragments of the structure of polyacrylonitrile fiber, the monomerization composition (condensing components of the polymer matrix), and “Polikon K” – “Polikon K
1a
” material. The dynamic contact angle of the investigated material was experimentally determined, and the work of adhesion (1.154 mJ/m
2
) and wetting (73.855 mJ/m
2
) of the surface material was calculated. The model of the structure of the “Polikon K
1a
” material indicates the most likely point of interaction of copolymer polyacrylic fiber with reactive CH
3
– groups of the polymer matrix, namely, the interaction with the C≡N group, by breaking one bond and forming a methylene bridge. The size of the unit cell of the model was estimated: 10.6 × 10.3 × 9.7 Å. The dependence of the torsion angle near the methylene bridge on the concentration of water molecules was investigated.
