A hose assembly with reduced axial stress including an underlying hose, such as a composite hose, and one or more elongate matrices extending over a portion of the hose along an axis of vibration. The elongate matrices can be an extruded, molded, or braided matrix formed of engineered fibers, metallic materials, and/or elastomeric materials formulated to impart a desired amount of rigidity along an axis of vibration to which it is applied. The elongate matrix can be a composite matrix including one or more rigid members, such as wire rods, embedded in an elastomeric matrix which is chemically and/or mechanically coupled to the underlying hose.
A composite hose assembly including a fluropolymer inner tube and a jacket circumferentialiy surrounding the fluropolymer tube. The jacket is formed from a plurality of plaits of fiberglass lace or other material. The jacket is then coated or infused with different resins along an axial length of the tube to impart varying degrees of flexibility along its length. A method of making the composite hose assembly includes: providing a fluropolymer inner tube, forming a jacket by circumferentialiy wrapping a plurality of plaits of fiberglass lace or other material around the fluropolymer tube, and infusing the plaits with different resins along its length to vary the flexibility.

A high pressure gas hose and related methods of transporting high pressure gases in which gas permeability throughout a length of the high pressure gas hose is reduced. The high pressure gas hose can have an outer tube and the inner tube. The outer tube can be formed of a resistant polymer material such as PTFE. The inner tube can include a matrix formed of PTFE and graphene nano-platelets or nano-particles. The graphene nano-platelets define a tortuous path within the matrix such that gas permeability is reduced through an inner tube wall thickness. Gas permeability throughout a length of the high pressure gas hose can be less that about 20 ml/m/hr. The high pressure gas hose can find practical application in natural gas applications, automotive applications, cooling and refrigeration applications and other applications in which it is desired to have low gas permeability in high pressure applications.
