Abstract
The resistance of high-strength para-aramid and polyethylene terephthalate fibres to soil microorganisms was investigated. It was found that the curve of the fibre strength versus the duration of exposure to soil microflora is monotonically diminishing. The elongation at break of the fibres also changes monotonically, with the exception of Kevlar. The change in the strength and elongation at break as a function of the duration of exposure in the soil is approximated by exponential equations can be used to predict the change in these indexes. The values of the coefficients in the equation are found. A comparison of the features of the change in the mechanical characteristics with the features of the molecular and supramolecular structure allows assessing the role of both the plasticizing effect of water and microbiological degradation. The increase in the deformation characteristics with a simultaneous decrease in the strength of para-aramid fibres, especially SVM, can probably be attributed to the effect of plasticization and the lability of their structure under the effect of moisture.
