Acoustic-optical criteria of analysis of orientation ordering in some fiber forming polymers

Conclusions A correlation was established between the scalar field describing the ordering of the structure and the tensor field characterizing the elastic constants of a material. It was proved that it is possible to use the acoustic and optical criteria for the analysis of the structure of some oriented fiber forming polymers. It was shown that the correlation between the suggested acoustic criteria can be used for optimizing the process of orienting drawing.Translated from Mekhanika Kompozitnykh Materialov, No. 5, pp. 771–775, September–October, 1986.
