The invention discloses a repair agent circulated feeding device and process for damage self-repairing composite materials and relates to the technical field of composite material damage self-repairing. The repair agent circulated feeding device for the damage self-repairing composite materials mainly comprises a valve a, a valve b, a valve c, a valve d, a valve e, a pump, a pipe network, a repair agent storage tank and a pressure meter. The outlet pipe of the pump is divided into two branches, one branch is connected with the repair agent storage tank through the valve e, and the other branch is connected with the inlet of the pipe network in the self-repairing materials through the valve a via the pressure meter, another branch at the rear of the valve a is connected with the repair agent storage tank through the valve b, the outlet of the pipe network is connected with the inlet of the pump through the valve d, and another branch of the valve d is connected with the repair agent storage tank through the valve c. The repair agent circulated feeding device and process for the damage self-repairing composite materials facilitates full filling of repair agent into the pipe network and achieves updating of the repair agent in the pipe network, and meanwhile, is high in efficiency, energy-saving and simple in operation.
Description
technical field [0001] The invention relates to a repairing agent circulating supply device and process for damaged self-repairing composite materials, belonging to the technical field of composite material damage self-repairing. Background technique [0002] Due to the characteristics of light weight, high strength, convenient processing and forming, and chemical corrosion resistance, composite materials have been widely used in aerospace, automotive, electrical and electronic, construction and other fields, and have developed rapidly in recent years. However, in the application of composite materials, local damage and microcracks will inevitably occur, which will cause macroscopic cracks and breakage, which will affect the normal use of materials and shorten the service life. The restoration of materials, especially self-healing is a very important issue. [0003] The traditional self-healing material is a capsule-type self-healing material. Microcapsule particles contain...
