Abstract
The chemical resistance of glass fibre laminates to petrochemical environments has to be evaluated before they can be adopted for use in petroleum storage tank applications. In this paper, the behaviour of isophthalic polyester glass laminates in the revised CEN test liquid, proposed in the draft CEN Standard, is compared with the corresponding behaviour in unleaded petrol, super unleaded petrol, diesel, and EEC Mixture (composition B). The chopped strand mat (CSM) laminates were tested under single-sided contact conditions with these liquids and with their vapours for 1000 hours at (50±1)°C, using the apparatus and procedure specified in the draft CEN Standard. Changes in the surface profile and percentage retention of flexural properties after exposure are reported.
