Приведены результаты исследований свойств нового композиционного материала, основанного на эпоксидной смоле с добавлением 3 % порошка графена, полученного экономичным и производительным методом самораспространяющегося высокотемпературного синтеза (СВС) из целлюлозы. Целью исследования являлось выявление влияния полученного новым методом графена на прочность композиционного материала посредством сравнения разных показателей прочности его образцов. Для этого сравнивали результаты механических испытаний и зарегистрированных сигналов акустической эмиссии (АЭ) до и после включения частиц активированного графена в состав материала. Представлены многоуровневая модель потока импульсов АЭ, технологии получения образцов и методика их испытаний. Показаны связанное с совершенствованием физической наноструктуры материала упрочняющее воздействие графена, перспектива разработки методов неразрушающего контроля и диагностирования прочностного состояния изделий.
