Abstract Shape memory polymer composites (SMPC) are a new kind of smart materials where many researches have been carried out.
In SMPC, shape memory polymers serves as a matrix material and particles or fibers act as reinforcements.

Introduction Friction Stir Welding (FSW) is a purely mechanical joining process in solid state, which is based on heating by friction and plastic deformation of the materials to be welded.
Due to the high quality of the welding, without adding other material between two parts of different or identical materials, it stirs up interest in understanding phenomena that characterize the thermo-mechanical process.

The results allowed us to affirm that the characteristics of this glass, in comparison with the tooth hard substances and other commonly employed inorganic dental materials, recommend it for further utilization in the dental field.
Ceramics are generally defined as inorganic, non-metallic materials.
Stress increased mutation phase contribution to the toughness .The composite material similar to natural tooth volume density, strength and hardness of natural teeth and excellent fracture toughness of dental materials to meet the performance requirements and the use for the special environment.

Influence of an Anti-chloride Corrosion Admixture on Density of Cement-based Materials Wei Zhang1, a, Xiao Yao1,b and Ru Mu2,c 1College of Materials Science and Engineering, Nanjing University of Technology, Nanjing 210009, P R China 2Collage of Civil Engineering, Hebei University of Technology, Tianjin 300401, P R China a7656279@qq.com, byaoxiao@njut.edu.cn, crmu@hebut.edu.cn Keywords: anti-corrosion admixture, concrete, durability, density.
The results show that the new admixture is effective to increase the density of cement-based materials.
The dosage of the new admixture is 3~5% of the total binding material in concrete or mortar.
l Simultaneous addition of fly ash and GGBFS in cement-based materials can increase the density of the matrix of the composites, which is also help to improve the resistance of the composites against chloride penetration.
