In order to solve this problem, the development of composite materials with better performance and the development of structural design and manufacturing technology of materials have become one of the important development directions in the future.
As a new type of functional and structural material, the materials have a series of advantages, such as large structural design freedom, light weight, high specific strength and specific stiffness, good fatigue resistance and corrosion resistance, and strong structural design[6-9].
As a structural and functional integrated material, high-performance carbon fiber composites are typical representatives of advanced composite materials.

However, the use of traditional bending patterns (moment bending) results in narrowing in bending zone, and for high-strength materials to greater bending radii, which degrades performance of profiles.
The research was carried out for materials AlMn, AlMg6, D16m, D16t from 0.8 to 3 mm in thickness, with rounding radius from 1 to 4 mm.
Functional relationship between springing angle and flange exceeding height for materials AlMg6, AlMn (S is the parent sheet thickness; r is the rounding radius; z is the gap between the punch and the die) The most uniform distribution of material over the part thickness is achievable for materials AlMn and D16.
Springing angles for these materials and minimal as compared with other materials.

Study on preparation of solid concrete brick with recycled aggregate Qijin Li, Guozhong Lia, * Shandong Provincial Key Laboratory of Preparation and Measurement of Building Materials, School of Materials Science and Engineering, University of Jinan, Jinan, Shandong, 250022, China amse_ligz@ujn.edu.cn, *correspondence author Keywords: Construction waste, Recycled aggregate, Solid concrete brick, Water cement ratio.
Waste clay brick and waste concrete were the main part in construct waste and through sorted, crushed, screened and classified, they could be made into recycled aggregate to become raw material of building materials, which could not only solved construct waste disposal problems, but also reduced natural sandstone exploitation, so it had important social and economic benefits [2,3].
Experimental Experimental materials.
Secondly the iron materials, wood materials and organic material in construction waste were removed by magnetic separation and pneumatic separation, and then the construction waste particles with a size of 5~40mm was obtained by screening and those construction waste particles whose size was less than 5mm were mainly clay particle and cement mortar particle and it would be removed.

Abstract.“5.12 Wenchuan earthquake”triggered floods, landslide, collapse and secondary geological disaster, trigger a new soil and water loss, having the significant influence to the local river water quality.This article through the statistical analysis of minjiang river and jiangyou wenchuan, beichuan station 2006 ~ 2011 water conditions material, discussing the before and after the earthquake disaster areas of river water quality change characteristics.
Materials and Methods We chose minjiang river (Wenchuan water source), jiangyou station and beichuan station to investigate the water quality, and select ammonia nitrogen, total hardness, these two indicators to analyze the change trend of the water quality before and after the earthquake.Through the use of gray dynamic model group method, using different time data set up different gray GM (1, 1) model to construct the gray forecasting model group, as the earthquake disaster areas water quality prediction model.Water quality monitoring data are provided by Sichuan Soil and Water Conservation Ecological Environmental Monitoring Station.
