摘要： An electric fuse has a casing of synthetic-resin-glass-cloth laminate which includes a plurality of re-inforcement plies - of woven glass fiber cloth - to the exclusion of any non-woven mat material. There are along the wall of the casing cyclically alternating regions of relatively large and relatively small glass-to-resin content, which allows to impart substantially the same wall thickness to the entire perimeter of the casing.

摘要： This invention relates to electric fuses having tubular casings having a high bursting strength and to the method and materials by which these casings are made. Such tubular material has also other applications than casings for electric fuses. Tubular structures made in accordance with U.S. Pat. No. 3,979,709 of which this is a division thereof have a plurality of plies which may include strips of non-woven, non-uniformly oriented glass fiber mat, composite strips of woven glass fiber cloth and non-woven glass fiber mat and glass fiber rovings. The plurality of strips are self overlapping and their overlaps are angularly displaced relative to one another. The tubular structure further includes a synthetic thermosetting resin integrating the plurality of strips into a multi-ply laminate.This invention relates to a process of manufacturing tubular structures of the above referred-to kind by pultrusion. The process includes steps for sequentially arranging the constituent plies of the tubular structure in their required positions, and for integrating the same to a unitary tubular laminate.

摘要： An electric fuse comprises a fusible element, arc-quenching means surrounding said fusible element, a casing of synthetic-resin-glass-cloth laminate housing said fusible element and said arc-quenching means, and a pair of terminal elements arranged at the ends of said casing and conductively interconnected by said fusible element. Said casing includes a plurality of plies, at least an outermost ply and an innermost ply, both formed by woven glass fiber fabric and at least one intermediate ply formed by a glass fiber mat having non-uniformly oriented fibers. The outermost ply and the innermost ply each form an overlap extending substantially in a direction longitudinally of said casing. Both overlaps are angularly displaced. The casing further includes a thermosetting resin integrating said outermost ply, said innermost ply and said intermediate ply into a laminate. The glass fiber density of said laminate is locally increased at the region of said overlap of said outermost ply, and at the region of said overlap of said innermost ply, to such an extent that the wall thickness of said casing is virtually uniform along the entire periphery or perimeter thereof.Further disclosed are modifications of the above tubular casing structure having a larger number of plies than three.
