Abstract
A method for making hollow stiffening elements with co-curing technique on a structure made of composite materialincludes the use of at least a lamination and polymerization spindleupon which is positioned at least a rolled section. The rolled sectionforms at least a hollow structurewhere there is the spindle, including the following operational phases: coating the spindlewith at least a first anti-adherent layer; coating the spindlewith at least a second heat-shrinking layer; heating the coated spindle; positioning the spindleon the surface of the structure; laminating the surfacethrough at least a rolled section; heating the structurewith at least a positioned rolled section; extracting the spindlefrom the hollow structure
