A composite tubular assembly formed by a core or tube which is reinforced by a multitape product which is wrapped in alternate non-bonded helical wraps on the core or tube. Each tape is first formed by impregnating a fibrous strip with a resin and then such tapes are fed from spools to the core of the tube.
1. A method of forming a composite tubular assembly, comprising:superimposing a first set of a plurality of thin flexible strips of material substantially coextensively with each other; applying an adhesive between the strips to bond the strips together; and positioning said bonded strips on a fluid conducting tubular core of flexible material in a non-bonding relation to said core to provide sliding relative movement therebetween upon the flexing of said tubular core.
