Introduction The reason that the compound materials have the outstanding performance is that it synthesized the respective characteristic of reinforcing material and the basis material, but must be able to realize through interfacial sheat, therefore the contact surface shearing strength has decided the mechanical properties of compound materials to a great extent.
DAOP resin is widely used in electronic products, precision instrument, plastic lenses, building materials and other industries.

Introduction With recent development and application of composite materials and structures in civil engineering, the analysis of fracture mechanisms of interface bond between the conventional materials and composites has received a lot of interest.
As the stress near the interface edge of dissimilar materials and at the tip of interface crack is oscillatory singularity [1], besides the strength and service life of interface is different from the base metal, the traditional strength evaluation method is not used to evaluate the strength of dissimilar materials or interface fracture behaviors, such as the stress in material mechanics.
Therefore it is necessary to develop a characterization methodology, which can measure the fracture toughness of combinatorial materials.

This can be achieved by altering the surface composition with addition of ceramic materials.
The addition of ceramic materials to the surface can be done by application of high energy electron beam irradiation, laser surface alloying and friction stir processing methods.
