Table 1 lists most of the current application phase change building materials [4].
In China , by adding phase change material to the matrix we got insulation materials that could be used for building envelope.
By the addition of phase change materials heat storage properties of materials are improved,and the thermal stability of the material is also improved, and does not affect the strength, durability and other properties of materials. [5] The advantages and disadvantages of phase change materials Composite technology of phase change materials mainly includes:(1)put thePCM package ( including container packaging, microcapsule encapsulation ) into building materials;(2) permeate PCM into porous matrix by immersion ( such as gypsum wallboard, concrete etc. ); (3)the PCM is directly mixed with building materials; (4) add the organic PCM to the building materials after emulsion.
Phase change materials as a new building insulation materials, has great advantages compared with sensible heat insulation materials, but it also has some problems, mainly includes[7]:(1) Type of phase change material is not available; (2)Preparation process of phase change building materials is not perfect, in order to prevent leakage.Considing with evaporation of phase change when used, they should be packaged, but package technology of phase change materials at present is still not perfect, this is also important problem of the phase change materials; (3)The high cost of the phase change materials when used.

Then, the optimum topology of macro-structure and modulus matrix of cellular materials will be obtained under this configuration.
Despite these successes, most topology optimization problems were modeled to design the structures or materials independently.
The present work is an attempt to achieve ultra-light structures composed of cellular materials by topology optimization.

The relationship between similar material and the raw materials was analyzed.
The results show that choosing different materials can compound different similar materials with different requirements.
