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 esterplatinum 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 fibervinyl ester composites is established.
