Abstract
A method for making spectacle arms from composite material with differentiated rigidity, the arms defining a first portion and an adjacent second portion which is less rigid than the first portion. The method includes: providing a first layer of non-cross-linked fiber-reinforced polymer material in the first and second portions; providing a separating element in the first portion, and superimposing a second layer of non-cross-linked fiber-reinforced polymer material on the first layer so as to cover the separating element at the first portion and contact the first layer at the second portion; subjecting the first layer, the second layer, and the separating element interposed between them to a molding process at predetermined pressure and temperature levels so as to cross-link the polymer of the composite material, thus obtaining a thickness and rigidity of the arm at the first portion which are greater than the thickness and rigidity at the second portion.

Abstract
A method for making arms for spectacles from composite material with differentiated rigidity, wherein at least a first portion (2a) and a second portion (2b) adjacent to the first portion and less rigid than the first portion are defined in the arm, comprises the steps of: - providing at least a first layer (11) of non-cross-linked fibre- reinforced polymer material, in the first and second portions of the arm; - providing a separating element (13) in the first portion (4), and - superimposing at least a second layer (12) of non-cross-linked fibre- reinforced polymer material on the at least one first layer (11), so as to cover the separating element (13) at the first portion (2a) and so as to be in contact with the first layer (11) at the second portion (2b); - subjecting the first layer (11), the second layer (12), and the separating element (13) interposed between them to a moulding process at predetermined pressure and temperature levels, so as to cross-link the polymer of the composite material, thus obtaining a thickness and rigidity of the arm at the first portion (2a) which are greater than the thickness and rigidity at the second portion (2b).
