Process for obtaining pipes and joints from a polymer composite

A process for obtaining pipes and connections from a polymeric composite, comprising:

• forming one internal pipe with a thickness from 3.0 to 8.0 mm using a fiberglass and epoxy resin matrix;
• molding the internal pipe in a polished metallic mold by filament winding a first layer of roving wire at a winding angle of 52° to 55°, impregnating the first layer with epoxy resin, and catalyzing with a heat curing agent having an aromatic amine base, anhydride, and aliphatic amine;
• forming the extremities of the internal pipe with a mold having molded screw threads, using a composite with an epoxy resin and carbon fiber base;
• fixing the extremities of the internal pipe in an equipment which provides traction and prevents buckling;
• rotating the internal pipe to a speed of 35 rpm;
• applying a water sandpaper to the entire external surface of the internal pipe in order to decrease brightness and increase adherence thereto;
• cleaning the internal pipe after sanding;
• and
• washing the internal pipe with an acetone-based degreasing composition.
