ABSTRACT:
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.
