One kind of self-repair rt fiber reinforced epoxy composite material and its preparation method

The present invention discloses a self-repairing rt fiber reinforced epoxy composite material and its preparation method, the method embedded in the inter-fiber reinforced epoxy composite layer, restorative contains some amount of blowing agent is loaded by a capillary and restorative. After forming a composite material, it is heated to a temperature above the decomposition foaming agent so that a positive pressure within the capillary. When the material destruction and fragmentation of the capillary repairing agent initiator can rapidly flow to the fracture surface at a pressure driven and react, so the crack again bonded together, to repair damage to the material. This material has outstanding features are: capillaries can provide enough such that the restorative material has high efficiency of repair, while the introduction of the blowing agent, is to ensure the rapid capillary repair agent when the material flows out automatically destroyed.
