Low permeation structures from recycled composite material

A method of producing a pressure containing structure, the method comprising:

• receiving one or more recycled parts, the one or more recycled parts comprising a carbon fiber composite material;
• mechanically processing the one or more recycled parts to form a plurality of fragments;
• forming the pressure containing structure by fusing the plurality of fragments into the pressure containing structure,
• wherein the plurality of fragments are selectively oriented to generate a tortuous effect thereby producing a low gas permeability for the pressure containing structure for substantially containing a fluid within the pressure containing structure;
• forming a first layer of the pressure containing structure using a first portion of the plurality of fragments selectively oriented in a first selected direction;
• and
• forming a second layer of the pressure containing structure using a second portion of the plurality of fragments selectively oriented in a second selected direction distinct from the first selected direction.

A pressure containing pipe comprising:

• a carbon fiber polyether ether ketone (PEEK) material configured to provide a low permeability pressure seal for containing a fluid inside the pressure containing pipe;
• and
• a plurality of fused mechanically recycled fragments comprising the carbon fiber PEEK material,
• wherein the carbon fiber PEEK material has a random fiber distribution that generates a tortuous effect to thereby reduce a permeability of the pressure containing pipe.
