The Impact Of The Morphology Of Reinforced Body On The Mechanical Behavior Of Titanium Matrix Composites

Nowadays, in the field of metal composites, titanium matrix composites are widely usedin many industrial areas, which has brought convenience to many industries. With the hightemperature resistance, high corrosion resistance, excellent secondary processing andcomprehensive performance, the titanium matrix composites have been extensively used inmarine, petroleum, chemicals, aircraft manufacturing and other fields. According to theenhancement methods, Titanium matrix composites can be divided into continuous fiberreinforced Titanium matrix composites and particulate reinforced Titanium matrixcomposites. However, due to the presence of anisotropic fiber reinforced Titanium matrixcomposite materials, manufacturing technology complexity, high cost and other reasons,many domestic and foreign research scholars have begun to study particle-enhancedmechanical properties of titanium matrix composites as a new phase of the major researchdirection and goal. After numerous experiments and data exploration, scientific research hasgained fruitful harvest which will provide a favorable theoretical basis for the developmentof particle enhanced titanium matrix composites.In this paper, based on the finite element model of particle enhanced titanium matrixcomposites, we have used the large general structural analysis software ANSYS to analyzeof the mechanical properties of composite materials in microscopic model, explore anddiscuss the relationship and influence between body and enhance in the composite materials,which mainly includes the following contents:（1）Establishing a finite element model, analyzing the impact of the reinforcingparticles shape on the interfacial stress distribution of titanium matrix composites.Respectively modeling and analyzing the different distribution of stress field betweencircular spherical particles and cylindrical particles. The result shows that, the reinforcedeffect of the circular spherical particles on the particulate reinforced titanium matrixcomposites is better.（2）Establishing the three-dimensional analysis model of the carbon nanotubereinforced titanium matrix composites. Applying a load and observing the results of thestress cloud. The study finds that the top position of the carbon nanotube in the matrix, stress comparison clearly shows a sharp change tendency. While in the central position of thecarbon nanotube, the changes become flat, stress on this area turns to be a stable value.Therefore, we believe that the central area of the carbon nanotube suffers full loadtransmission.（3）We use ANSYS to establish the three-dimensional model of the carbon nanotubereinforced titanium matrix composite analysis, to study the different impact on the compositeinterfacial stress distribution when carbon nanotube in different phases angle distribution. Bycomparing the results, we find that when the phase angle=15o, the enhancement effect ofparticulate reinforced titanium matrix composites is better.
