leaching of e-glass fibres with hcl and its effect on the reaction of fibre with chlorosilanes were studied by ftir spectroscopy and thermal analysis. leaching removes basic oxides from the fibre, increases fibre surface area and causes intense surface hydration as well as water diffusion into the fibre. fibre hydration can be reduced by drying the fibre at high temperatures. surface hydration increases the amount of polyvinylsiloxane coating formed when fibre reacts with vinyltrichlorosilane in refluxing toluene, but prevents the fibre from reacting with monochlorosilanes in toluene or aqueous solution.
