N2 - Raman spectroscopy, plasma emission spectroscopy, electron spectroscopy for chemical analysis (ESCA), elemental analysis, solution conductivity and pH, were used to characterise the solutions and the acid, base and silane-treated E-glass fibres. Strong acids and bases induced an ion exchange reaction, which caused large quantities of aluminium and calcium to be leached from the E-glass surface. Samples treated with strong bases were found to have large quantities of sodium on the E-glass fibre surface; this came from the sodium hydroxide used to treat the fibres and from the bulk of the fibre. A cyclic isocyanurate silane, which was only partially soluble in water, was detected on the E-glass surface. A cationic amino-functional silane ester with a long organic chain did not completely hydrolyse in an aqueous solution adjusted to pH=4. The solution concentration, which gave the maximum amount deposited, was different for each silane tested. © 2001 Elsevier Science B.V. All rights reserved.
