Composite materials are formed from two or more materials producing properties that could not be obtained from any one material.
The role of the matrix material is to protect the reinforcement materials , to distribute the stress to the reinforcement material(s) , to provide for the final shape of the composite part.The role of the reinforcement material(s) is to provide the composite high mechanical properties , to reinforce the matrix in preferential directions.The properties of a composite material depend on the nature of the reinforcement and the matrix, the form of the reinforcement (particles, fibres) and the relative content of reinforcement Literature review: Hashim (1999) et al studied that combining high specific strength with good corrosion resistance, metal matrix composites (MMCs) are materials that are attractive for a large range of engineering applications.

The key is to properly treat all the factors that may cause cracking.
In order to apply drying shrinkage test results (sizes of test specimen: 10×10×40 cm, relative humidity: 60 %) to actual engineering, various drying shrinkage estimation methods are put forward in the world, such as ECB/FIP method, ACI method, and JCI method, etc.
Any of those methods can be used to estimate the drying shrinkage of concrete structure by multiplying with a series of correction coefficients considering the factors such as environment temperature and humidity, concrete mix proportion, curing method, sizes and reinforcement ratio of the actual engineering structure.
It is a good idea proven in engineering practice to utilize the autogenous volume expansion of concrete to balance out partial harmful shrinkage.
After optimizing of concrete mix proportions, the content of cementitious materials (cement and fly ash) has been saved by 20-40 kg/m3.

Gelatin derived from the collagen of mammalian skin and bone providing stability and elasticity is more used in food packaging materials such as edible films.
Due to worthwhile structures like high surface area, high porosity, small dimensions, and high flexibility, electrospun nanofibers are appropriate scaffolds to produce novel antimicrobial materials.

Introduction Advanced composite laminates have been extensively used in many structural applications, especially in aerospace engineering due to their strength/weight ratio relative to metallic materials.
Composite materials and structure can delamination along weak interfaces by failure modes that create a large-scale fracture process zone.
Piezoelectric materials (such as PZT) and structures have received a deserving attention in the recent years, in virtue of their self-monitoring and self-controlling properties.
In many engineering applications, these piezoelectric smart structures may experience various impact events [14].
The friction between fiber and matrix material of this pull-out process contributes to the fracture resistance of the crack.

Base design should pay attention to the protection of traditional residential culture, conform with the local natural conditions, using the local building materials, and following the regional architectural features.(2) maintain the farmland landscape.
Promote ecological agriculture vigorously.The ecological agriculture sees agricultural as an open ecology, economy and technology compound system, follow the natural and economic laws, the use of ecology principles, systematic engineering methods and modern science and technology, organizing and planning the agricultural production according to local conditions[3].
Our country region is vast, differences between natural conditions, resources foundation, the economy and social development level is large , people should construct multilevel agriculture ecological system according to regional actual situation, using the biological mutual benefit symbiotic relationship form a multi-level agricultural ecosystem, and through the food chain network, and comprehensive utilization of agricultural waste resources, give full play to the resource potential and species diversity advantage, so as to establish a good material cycle system, and promote the agricultural steady development, realize the unity of rural economic, social and ecological benefits .
Joint participation of all residents, and active maintenance of the ecological environment are the key links to solve ecological environment problems.

The method mainly tests the change of material’s property with continuous temperature change.
Commonly used methods are: step-by-step cooling curve method, differential thermal analysis, thermal expansion method, conductivity method, hot quality standard and X-ray diffraction method, etc. 2) Statistic method: usually, the relationship between material properties and temperature is measured with temperature preservation.
The experiments needed are mostly based on manmade material mixture.
Therefore, the activity coefficients become a key factor in the process of phase diagram calculation.
