The establishment of the physical model Related hypothesis. 1) Material continuous and for isotropic; 2) the laser absorptive of materials surface not changing with temperature; 3) Ignore the molten pool flow; 4) Ignore material vaporization; 5) Because of laser heating time is very short, do not consider molten pool liquid flow on temperature field influence.

Composite materials have superior properties than those of the individual components when used alone depending on the type of materials being combined [3].
The concept behind composite materials is the combination of two or more materials in creating a new engineered material [4].
The classification of composite materials is based on the binder material, which binds or holds the filler materials, usually a polymer matrix, and the filler material, usually the fibers, sheets, fragments, particles, or whiskers of natural or synthetic material [1].
