Experimental Study of a Certain Type of Aircraft Structure Repair Adhesive

Based on a certain type of aircraft structure repair adhesive was studied, the curing temperature of aircraft structure repair commonly used adhesive process of high, long curing time, curing thermal stress problem, with epoxy resin as basic material, by adding elastic toughening Ding Jin g rubber, curing agent and silane coupling agent modification on Toughening of epoxy resin. The mechanical properties of adhesive were analyzed through the cyclic loading test and tensile shear test, and the best ratio of modified epoxy resin adhesive. The adhesive prepared at 80 °C for 90 min after curing shear strength can reach 35MPa, which can meet the aircraft structure damage daily emergency repair requirements.

Modified Epoxy

The nano-particle modified epoxy resin adhesive was prepared by adding different types of nanoparticles to the epoxy resin adhesives.The influence of the kinds and amount of nanoparticles on the mechanical properties of epoxy resin adhesive was investigated.The investigation results indicated that the addition of three kinds of nanoparticles including nano-silica,nano-titanium dioxide,nano zinc oxide to epoxy resin adhesive has a significant influence on the mechanical properties of nano-composites.And tensile strength and breaking elongation of nano-composites reached the maximum when the amount of nanoparticle reached 4wt%.In addition,the toughening mechanisms of nano-particles modified epoxy resin adhesives was analysed.
