Document Type and Number:
Japanese Patent JP3061413
Kind Code:
B2
Abstract:
A thermoplastic impregnated fiberglass pipe or tube and the process for making such pipe are disclosed. The pipe or tube is made of thermoplastic impregnated fibrous roving which consists of a plurality of glass filaments, at least a portion of the filaments' surfaces being in contact with the residue produced by evaporating water from an aqueous size composition consisting of an organosilane coupling agent, a polyethylene oxide binder material, and a polypropylene thermoplastic polymer resin, wherein the composition is applied to the glass fiber during the fiber forming process. The pipe forming process includes filament winding the rovings around a spindle and thereafter heating the wound rovings to fuse the thermoplastic polymer resin.
