Fabrication method of CARALL hybrid composite material for aircraft structure

摘要

The present invention relates to an aluminum hybrid composite material is in progress is a recent study on the aircraft structure material active, the adhesive side of the aluminum sheet, and a vapor degreasing and phosphoric acid anodizing, the semi-solid carbon / epoxy pre-fracture the primary curing the mixture to change to a solid laminate, anodized aluminum plate with an adhesive film and a method of manufacturing a hybrid composite material karal by laminating the carbon / epoxy laminates characterized by a secondary curing.; The method of the present invention to form fine irregularities on the surface of the plate material by suitably applying of phosphoric acid anodizing pre-treatment methods commonly used for the bonding of metal-to-metal contact surface of the aluminum sheet is very effective to reduce the maximum of the absorption force for the outer adhesive , after the first curing the carbon / epoxy-free fraction of aluminum sheet and is written because adhesion with the laminate of the solid adhesive film in between was avoid dimensional changes in the number, which can occur when the secondary curing resin layer.; Karal hybrid composite material manufactured by the method of the invention is an aluminum plate with a high bonding strength between the carbon fibers can strengthen a composite resin in mechanical properties such as strength and toughness equivalent to conventional hybrid composites or indicate the superior properties over depending on which is expected to be useful as structural materials for aircraft.
