Abstract
Different magnetic treatments were investigated and recommendations were made concerning industrial application of magnetic treatment of fibres freshly impregnated with binders in fabrication of reinforced PCM to strengthen them significantly, as the most simple, economical, and efficient type of magnetic treatment. A correlation was found between the relative changes in the degree of orientation of the molecules of the oligomers and the strength properties of materials fabricated using a static magnetic field. It was found that the strengthening effect of the magnetic treatments has a complex structural and adhesive mechanism. Used in reinforcing fibres, where formation of hydrogen bonds with the binder is characteristic, the σ b and α im of the materials simultaneously increase as a result of the magnetic treatments, contradicting the classic theory of cross-linked polymers. The ratio of the relative changes in σ b and α im is a function of the reciprocal orientation of the reinforcing fibres and the lines of force of the external static magnetic field.
