    (54) METHOD OF MODIFICATION OF FIBER FROM POLY (PA-PHENYLENTEREPHTHALAMIDE) (57) The invention relates to the technology of chemical fibers, in particular to chemical modification of poly (nylene terephthalamide) fiber, and can be used in the preparation of composite materials. The invention provides an increase in the interlayer shear strength of a composite material based on this fiber due to the fact that the fiber is impregnated with an aqueous solution of trimethylol-propane-trisGbate (N-aziridinyl) propionate T, or pentaerythritol tris-beta (I-aziridinyl) propistate, or trimethylamine lolpropan-tris beta (K-2-methylaziridinyl) propionate to contain an agent on the fiber 0.1-10 wt.%. 1 tab.

    The invention relates to the field of chemical fiber technology, in particular, to the chemical modification of poly (para-phenylether β-amide) fiber and can be used in the preparation of composite materials.
    The purpose of the invention is to increase the interlayer shear strength of the composite material based on the specified fiber.
    Example 1.12.0 g of yarn from poly (yara-phenylene terephthalamide) 1420 denier is impregnated with a 1% aqueous solution of trimethylolpropane-tris β-beta (N-aziridinyl) -propionate (I) or pentaerythritol-tris (beta) (N-aziridinyl ) - propionatase (I), or trimethylpropane-tris {β-eta (N-2-methylaziridinyl) p opionate (III) to contain an agent on the fiber 1.0 wt.%. Wrap the fiber on an aluminum conical bobbin and dry for 8 hours ovens at 105 ° C. The yarn is passed through an exhaust device and immersed in a tank with resin, and then wound onto a rectangular shape.
    As the resin used is a composition containing 100 mph. tixotropic polyester containing isophthalic acid units (Freeman Chemical KO Stipol 40-2990) and 2 wt.h. tertbutylperoxy-2-ethylhexanoate (Penvolt, Luperzol RDO, 50% solution) as a hardener. The rectangular shape has 2 cavities (152.5 mm long, 12.7 mm wide and

    12.7 mm deep. The resin-coated fiber is wound into these cavities. The cavities are covered with two plates and the screws are not fully wrapped in order to attach the covering plates to the form. Between the plates and the form is placed 4 pads 3.2 mm thick.
    The assembled form is placed in a vacuum chamber at room temperature JQ and is evacuated at a vacuum of 635 mmHg. Art. 30 min. The screws are tightened and cured for 1 hour at 130 ° C, then cooled to room temperature. Screws and plates are removed. Material 15 is cut into samples with the same winding thread (152.4 mm long, 12.7 mm wide, 3.2 mm thick). The volume of fiber 64t4%. The interlayer sdeig strength is measured in accordance with AZTMD 20 2344-76.

    Example 2. Yarn Kevlar, having the same denier as the yarn in Example 1, is passed through coating solutions containing aziridines in a concentration of 0.1-10%. Wet yarns are drawn through a spinneret with a hole with a diameter of approximately 0.085 mm, so that the yarn weight gain upon impregnation with the solution is about 100% by weight. The yarn is then wound onto open cards and dried as in example 1, to obtain fibers with a modifying agent content (coating) of 0.1-10%. From the thus modified yarns, the compositions were made as in Example 1, and improved bonding results were obtained, similar to those obtained in Example 1.
