Experimental investigation of creep behavior in Phenolic based polymer composites

The behavior of composite structures under applied loads and temperatures is one of the most important topics of research in composite materials. The creep properties of composite materials have very important effect on the behavior of the structure during life time. Among various investigations on creep behavior of polymeric composites, Basalt fiber reinforced polymers has been rarely investigated. In the present paper the creep of basalt/polymer composites with two different types of basalt woven including plane weave and satin weave are experimentally investigated. Creep tests were performed at three different temperatures: 100, 150 and 200 oc and also two mechanical stresses including 3.8 and 6.5 MPa. The results showed that strain rate in satin wave is reduced by 68% at 200 oc in comparison with the plane weave. Moreover, some other parameters such as failure mechanism and creep life of specimens were investigated.
