Abstract

A novel sheet produced by a wet process consists of a blend of glass fibres and synthetic fibres, the synthetic fibres constituting a tridimensional network during the formation of the sheet and ensuring the latter's weldability. The synthetic fibres can consist of a blend of at least two kinds of fibres, having different melting points so that a first kind of fibre can be made from synthetic material which softens during manufacture of the sheet and a second type of fibre can be made from a synthetic material which melts during welding of the sheet. The synthetic fibres can be composite fibres comprising an envelope made from a synthetic material with a softening point between approximately 100 and 140 C and a core with a softening point above 150 C. Application of the sheet as a separator for batteries.
