Strength loss in E-glass fibres after exposure to organic acids

Abstract

The corrosion of E-glass fibres has been investigated in aqueous solutions of selected organic acids. Although most organic acids have very little corrosive effect, oxalic acid and mesoxalic acid (2-oxopropanedioic acid) are extremely corrosive. The mechanism of the corrosion process appears to be related to three factors: relatively high acidic strength, formation of an insoluble calcium salt, and an ability to form stable complexes with cations present in the glass. This corrosion is extremely important when glass fibre composites are used in conditions where oxidative breakdown (e.g. by electric fields or ultraviolet radiation) of the resin material is likely to occur, as the two most corrosive organic acids are likely breakdown products.
