Effects of Composites due to External Fields

The Properties of polymer differs when subjected to various external fields such as pH, temperature and light. As the external fields react with the polymer it results in deformation. In the present world construction industry plays a major role in using of composite materials. The composites such as FRP and polymer concrete deforms due to various external fields of nature. The focus on the present paper is the effects happen in composite materials due to external fields. Here in this paper the composite materials FRP and polymer concrete is subjected to external field and its effect is found with a case study.
