Introduction
Widely used in civil engineering strengthening and reinforcing, modern fiber reinforced polymer (FRP) exhibit relatively elevated climatic stability, but in prolonged exposure to climatic factors, their properties can change[1].The extensive use of these materials in different branches of modern civil engineering poses the problem of a complex study of atmospheric aging of FRP.
Statistical results of material properties.
Suppose positive effect (enhance process) and negative influences (damage process) are independent, irreversible change of fiber reinforced polymer strength can be written as: (1) whereis strength value of composite materials after the aging time t; is initial strength value of the composite materials; is material parameter reflects curing degree of materials, is material and external environment parameter which reflects strengthen rate characteristics, is material parameter reflects resistance to crack propagation ability and is parameter reflects external environment erosive.

Among all multiferroic materials, BiFeO3 (BFO) is one of the rare multiferroic materials, exhibiting both ferroelectric and antiferromagnetic properties at room temperature with its relatively high Neel temperature (TN = 653 K) and Curie temperature (TC = 1103 K) [5].In past decades, many efforts have been made to synthesize single phase BFO.
For sol–gel route, bismuth nitrate (Bi(NO3)3·5H2O) and iron nitrate (Fe(NO3)3·9H2O) were used as starting materials, citric acid as chelating agent, and 2-methoxyethanol as solvent.
For hydrothermal route, bismuth nitrate and ferric chloride (FeCl3·6H2O) were used as starting materials, potassium hydroxide (KOH) as mineralizer.

Supply Chain
Supply chain is defined as a network of corporate organization in order to improve and enhance the flow of information and material between customer and supplier with the consideration of lower price and highest speed.
Environmental indicators cover performance related to inputs (e.g., material, energy, water) and output (e.g., emissions, effluents, waste).

The phosphobetaine amphoteric surfactant of N, N-dimethyl-tridecane hydroxyethyl ammonium phosphate (PBET-13), was synthesized by using epichlorohydrin, NaH2PO4 and dodecyl/tetradecyl dimethyl amine and cetyl/octadecyl dimethyl ammonium as raw materials.
In this paper, we synthesized the new surfactant of dodecyl/tetradecyl phosphobetain (PBET-13) based on the dodecyl/tetradecyl dimethyl amine as the main raw material, and its scale inhibition performance, interfacial tension and foaming performance were studied.

Introduction
Texture of materials causes anisotropy in material properties and sometimes can determine material
performances.
Generally, heavily deformed materials develop distinct microstructural features such as deformation or slip bands due to inhomogeneous deformation.
It can be concluded that the pattern quality is superior to the Taylor factor in the estimation of stored energy in real polycrystalline materials.
The grains belonging to <001>//ND orientation are easily deformable, i.e. soft, materials because of their low Taylor factor.

Experimental Procedure
2.1 Material
The reconstruction material was Höganäs amperprint 0717.074 - 316L stainless steel powder with an 8 g/cm3 density and was used to fill the damages.
It is worth to mention that the specimens were machined from laminated bar, that also justifies the hardness difference between the base and deposited materials.
Visually, there are no boundary marks between the base material and the new material, which makes the repair entirely satisfactory.
