Сравнительное исследование полимера, армированного стекловолокном, и полимера, армированного углеродным волокном, на кубе и цилиндре

В лабораториях Багдада проведен сравнительный анализ полимеров, армированных стекловолокном, с полимерами, армированными углеродным волокном, на кубе и цилиндре. Было отобрано 36 образцов с процентным содержанием волокна 1,0, 2,5 и 5,0 % от массы цемента. Методика данного исследования включала использование композиционных полимерных волокон во внешнем армировании бетонных балок для повышения прочности при изгибе при наклеивании полимерных волокон на поверхность. Выполнены испытания группы А неармированных бетонных балок с другими полимерными волокнами. Отличные результаты получены при добавлении двух типов полимерных волокон в бетон. Установлено, что полимер, армированный стекловолокном, имеет более высокие результаты, чем полимер, армированный углеродным волокном, при испытании образцов на прочность при изгибе. Однако прочность на раскалывание армированного углеродным волокном полимера достигла более высоких показателей, чем, армированного стекловолокном. Результаты группы предыдущих исследований, проведенных с целью изучения  влияния добавок фибры на механические свойства бетона, показали, что их добавка приводила к повышению сопротивления сжатию, растяжению и изгибу при скоростях, достигавших 25, 75 и 80 % соответственно.
