NOVELTY - The system comprises: a composite structure (110) comprising a first layer having a reinforced resin with a reactive group and a photoinitiator, and a successive layer comprising the reinforced resin having the reactive group and the photoinitiator; a first radiation source (118) configured to heat the layers of the composite structure throughout a thickness of the layers of the composite structure to form pre-heated layers of the composite structure; and a second radiation source (122) configured to cure the pre-heated layers of the structure.    USE - The system is useful for manufacturing and repairing composite parts such as wind blade.    ADVANTAGE - The system is capable of reliably, effectively and economically manufacturing and repairing the composite parts with high quality and without any damage.    DETAILED DESCRIPTION - The system comprises: a composite structure (110) comprising a first layer having a reinforced resin with a reactive group and a photoinitiator, and a successive layer comprising the reinforced resin having the reactive group and the photoinitiator; a first radiation source (118) configured to heat the layers of the composite structure throughout a thickness of the layers of the composite structure to form pre-heated layers of the composite structure; and a second radiation source (122) configured to cure the pre-heated layers of the structure through a thickness of the composite structure and the pre-heated layers of the composite structure and form a covalent bond across an interface (114) of the first layer and an adjacent successive layer and additional covalent bonds across additional interfaces of the successive layers. The first radiation source: comprises infrared radiation; and configured to emit radiation having a wavelength of 700 nm to 1 mu m and to heat the layers of the composite structure to a temperature of 40-100 degrees C. The second radiation source: comprises ultraviolet frequency radiation; and is configured to emit radiation having a wavelength of 100-400 nm. The first and second radiation sources are configured: as a combined radiation source; and as discrete stand-alone radiation sources. The first layer and the successive layers are configured in a stack. The composite structure comprises a component of wind turbine, and a wind turbine blade. An INDEPENDENT CLAIM is included for a method for manufacturing and repairing composite parts such as wind blade.
