Abstract:
A method for bonding an airfoil skin to an airfoil core, said method comprising the steps of:a) providing a varying thickness skin part for an airfoil;b) placing said skin part on a support plate;c) providing a core part for an airfoil;d) placing said core part on said skin part;e) covering said core part with an elastomeric caul component;f) covering peripheral margins of said elastomeric caul component with elongated semi-rigid caul components which are flexible in their direction of elongation, and are rigid in their direction which is transverse to their direction of elongation;g) covering said semi-rigid caul components with strips of said elastomeric caul component;h) subjecting said caul components to heat and pressure sufficient to bond said skin to said core.
