Assessment of small interactions and structural gradient at the interface of FRP composites by FTIR-imaging and DSC techniques

Abstract

Environmental degradation of FRP composite was studied. The degradation study basically included hygrothermal and cryogenic treatment. Study of chemical and mechanical behaviour at the interface of the fibre reinforced polymer composites is an area of research now a day. Many complex reactions occur at the interface due to moisture absorption, temperature and cryogenic treatment and very little information is available regarding the chemical deviation near the interface due to moisture absorption. Micro-composites were prepared to investigate the chemical deviation of hygrothermally samples and layered structures were prepared to study the mechanical behaviour of cryogenically treated samples.
