Blistering of Graphite/Polymer Composites Galvanically Coupled with Metals in Sea Water
Abstract
The electrochemical nature of blistering in carbon vinyl ester composites in sea water and saline solution was confirmed. Carbon fiber/ polyester composites also blistered. It was therefore shown that blistering is a generic degradation phenomena for many carbon containing polymer composites. The location of the fluid filled blisters in the composites was detailed. The aqueous blister liquid contains organic species and has a pH greater than 10. Blisters formed on vinyl ester/platinum composites caused degradation of the polymer which could not be duplicated in 10N sodium hydroxide solution. Absorption kinetics data for water and electrolyte in carbon fiber/vinyl ester composites is established.
