This topic develop the matrix composite pipes which has the ability of corrosion prevention and antiseep, also has the high strength of extension and stability, by using huge advantage of the corrosion prevention and antiseep performance of resin matrix composite, the high strength of extension of carbon steel, and also, the high stiffness of cement matrix composites. We design and optimize the structure of matrix composite pipes by study the relationship between deformation coordination based on the viscoelastic constitutive model of resin matrix composite, the homogeneity elastic constitutive model of the cement matrix composites. We obtain a basic method of design the matrix composite pipes from studying from theoretical analysis and numerical simulation.

The Cost

The SiC ceramic is the perfect ballistic material in the modern war because it has lower density, the weight is lighter and the cost is moderate. In this paper, the shearing academic modular of the epoxy resin matrix composite enforced promiscuously by SiC nano fiber and Twaron staple was built and proved by the way of mathematic deduced and testing validated. And the shearing characteristic was analyzed. The result shows that the total volume percentage of the enforced fiber is bigger, and the shearing modulus of the composite is higher. The modulus of the composite would be higher if that of the matrix is bigger. If the volume percentage of the fiber with lower shearing modulus is bigger, the modulus of the composite would be lower. The mainly factor which influenced the shearing characteristic of the composite is not the shearing properties of the enforced fiber, but that of the epoxy matrix. The effect to the shearing characteristic of the epoxy resin composite enforced by the mixture of SiC nano fiber and Twaron staple is plus certainly.

The force between every two Trusses of truss bridge is often very large, it can ruin the bridge easily. Thermosetting resin matrix composite can strengthen structural strength. In this text, the matrix composite is used to strengthen the strength of the Straight webs. Under tensile force and pressure, three kinds of analysis are made. By comparing the results of the analysis, it is obtained that reinforcing effect under tensile force is better than that under pressure

Modified Epoxy

The impregnation of the fiber with a resin system, the polymeric matrix with the interface needs to be properly cured so that the dimensional stability of the matrix and the composite is ensured. A modified epoxy resin matrix was obtained with a reactive toughening agent and anhydride as a curing agent. The mechanical properties of the modified epoxy matrix and its fiber reinforced composites were investigated systematically. The polymeric matrix possessed many good properties, including high strength, high elongation at break, low viscosity, long pot life at room temperature, and good water resistance. The special attentions are given to the matrix due to its low out gassing, low water absorption and radiation resistance. In addition, the fiber-reinforced composites showed a high strength conversion ratio of the fiber and good fatigue resistance. The dynamic and static of the composite material were studied by thermo gravimetric analysis (TGA), Differential Scanning Calorimetry (DSC) and Scanning Electron Microscopy (SEM) with EDX. The influences of processing technique such as curing and proper mixing on the mechanical and interfacial properties were determined. The results demonstrated that the modified epoxy resin matrix is very suitable for applications in products fabricated with fiber-reinforced composites.

ABSTRACTVery high strength castable chemically bonded ceramic (CBC) materials have been prepared which consist of finely chopped steel fibers and steel aggregate in a silica modified portland cement matrix. This paper examines the effect of metal fiber addition on compressive and flexural strengths. The overall chemistry of the matrix is held constant but the morphological form of silica used and the cure conditions are altered to examine their effect. Compressive strengths in excess of 500 MPa and flexural strengths in excess of 80 MPa can be obtained.It is found that flexural strength increases proportionally with fiber content over the range of 0 to 10% by volume. Compressive strengths are not affected. Use of silica fume in the mixes produces higher strengths at low temperatures than mixes which contain only crystalline silica. High temperature curing/drying (400°C), which produces the highest strengths, produces equivalent properties for formulations with and without silica fume. Higher water/cement ratios are found to reduce compressive strengths but have relatively little effect on the flexural properties.

Hybrid Metal Matrix Composite

The composite material is a combination of two or more materials with different physical and chemical properties. The composite has superior characteristics than those individual components. A hybrid composite is the one which contains at least three materials. When the matrix material is a metal, the composite is termed as metal matrix composites (MMC). The MMC is a composite material with two constituent parts, one being a metal. The other material may be another metal, ceramic or fiber. Among all the MMC’s, Aluminium is the most widely used matrix material due to its light weight, high strength and hardness. This paper deals with the fabrication and mechanical investigation of hybrid metal matrix composite Al - SiC. The fabrication is done by stir casting by adding the required quantities of additives into the stirred molten Aluminium. The results show significant effect of mechanical properties such as tensile strength, yield stress and flexural strength. The internal structure of the composite is observed using Scanning electron microscope (SEM) and found that are formation of pores in them.
