A fiberglass material contains glass fibers having graphite evenly distributed thereon. The graphite provides a coating that makes the fiberglass material substantially free of static electricity. Suitable graphite content of the fiberglass material is about 0.25 wt% to about 0.50 wt%, or about 0.25 wt% to about 1.0 wt%, or about 0.8 wt% of dry weight of the glass fibers. The graphite used may be synthetic material or natural material substantially free of silica. Other components of the fiberglass material may include de-dusting oil.
L'invention concerne une matière contenant des fibres de verre recouvertes d'une couche de graphite régulière. Le graphite forme un revêtement rendant la matière à base de fibres de verre sensiblement exempte d'électricité statique. La teneur en graphite appropriée de ladite matière est comprise entre environ 0,25 % en masse et environ 0,50 % en masse ou entre environ 0,25 % en masse et environ 1,0 % en masse, ou d'environ 0,8 % de la masse sèche des fibres de verre. Le graphite utilisé peut être synthétique ou naturel et sensiblement exempt de silice. La matière à base de fibres de verre peut être également constituée d'huile de dépoussiérage.
