(54) СПОСОБ ОПРЕДЕЛЕНИЯ СТОЙКОСТИ ПОЛИМЕРНЫХ МАТЕРИАЛОВ К РАСТРЕСКИВАНИЮ(54) METHOD FOR DETERMINING THE RESISTANCE OF POLYMERIC MATERIALS TO CROSSLY
II
Изобретение относитс к испытательной, технике и может быть использовано при определении стойкости полимерных материалов к растрескиванию.The invention relates to a testing technique and can be used in determining the cracking resistance of polymeric materials.
Известен способ определени стойкости полимерных материалов к растрескиванию, заключающийс в том, что образец материала изгибают по шаблону и определ ют врем до по влени трещин 1.A known method for determining the cracking resistance of polymeric materials is that a sample of a material is flexed according to a pattern and the time until the appearance of cracks 1 is determined.
Недостатком способа вл етс низка точность испытаний.The disadvantage of the method is the low accuracy of the tests.
Наиболее близким к изобретению вл етс способ определени стойкости полимерных материалов к растрескиванию, заключающийс в том, что образец материала закрепл ют в захватах испытательной машины , нагружают до заданной деформации, выдерживают в нагруженном состо нии до по влени трещин и по времени до начала по влени трещин суд т о стойкости материала к растрескиванию 2.The closest to the invention is a method for determining the resistance of polymeric materials to cracking, which consists in fixing a sample of material in the grips of a testing machine, loading it to a predetermined deformation, keeping it in a loaded state before the appearance of cracks and Judgment on cracking resistance of the material 2.
Недостатком способа вл ютс узкие функциональные возможности, исключающие выдержку образцов в различных услови х .The disadvantage of this method is the narrow functionality that excludes the exposure of samples in different conditions.
Цель изобретени - расширение функциональных возможностей способа путемThe purpose of the invention is to expand the functionality of the method by
обеспечени возможности выдержки образцов в различных услови х, например, при облучении или в агрессивных средах.enabling samples to be exposed to various conditions, for example, during irradiation or in aggressive environments.
Указанна цель достигаетс тем, что образец нагружают при температуре про влени высокой эластичности, деформированный образец охлаждают в захватах до температуры потери эластичности, освобождают образец из захватов, а перед выдержкой стабилизируют его размеры.This goal is achieved by loading the sample at a temperature of manifestation of high elasticity, the deformed sample is cooled in the grips to a temperature of loss of elasticity, freeing the sample from the grips, and stabilize its dimensions before exposure.
Способ реализуетс следующим образом.The method is implemented as follows.
