“…Therefore, in recent years, a series of excellent heat dissipation materials have been developed [1][2][3][4]. It is extremely important to design and develop packaging materials for electronic devices by compounding reinforcement with a metal matrix to obtain metal matrix packaging materials with good thermal conductivity and adjustable thermal expansion coefficients [5][6][7]. Copper has high thermal conductivity and good processing performance [8,9].…”

Graphite flake-carbon fiber coreinforced copper matrix composites were prepared by vacuum hot pressing technology. The carbon fibers were dispersed ultrasonic in alcohol and then mixed with graphite flake and alloys powder（Zr and Cu）for hot pressing sintering. The effects of the carbon fiber content on the microstructure, bending strength and thermal conductivity of the composites were investigated. The results show that the interface of the composites is well bonded. When the volume fraction of carbon fiber is 1%-3%, the carbon fiber can be uniformly dispersed in the matrix, and the bending strength of the composites can be improved effectively. When the volume fraction of carbon fiber is 2%, the bending strength reaches a maximum of 152 MPa, which is an increase of 60% compared with that of the composites without carbon fiber. However, an excessive addition of carbon fiber (4% or more) leads to an uneven distribution of carbon fiber, and the bending strength of the composites decreases. When the volume fraction of carbon fiber is 2%, the thermal conductivity of the composite is 597 W·m-1·K-1. The acoustic mismatch model (AMM) associated with the Digimat MF module is able to predict the thermal conductivity of the anisotropic multiphase composites.

“…The amine-grafted MWCNTs/binary resin (polyamide resin and epoxy resin) composites were prepared by conventional solution blending method and the corresponding material parameters can be obtained in the literature. [4][5][6] In generating the mesh, all the volume entities in the model were meshed with 10-node tetrahedral element to achieve better mesh quality and the converging rate. As a consequence of this, the complex geometry was discretized using approximately 6852 tetrahedral elements and 11,978 nodes.…”

“…[1][2][3] To achieve high performance of CNTs/resin composites, uniform dispersion of CNTs in resin matrix is the first step. In our earlier efforts, [4][5][6][7] we reported a facile synthetic scheme for producing amine-grated multiwalled CNTs (MWCNTs) using silane coupling agent; our strategy enabled the homogenous distribution/dispersion and excellent compatibility in resin matrix. The resulted composites exhibited great potential for application in thermal pyrolytic graphite/Al sandwich radiator derived from the greatly enhanced thermal conductive and mechanical properties.…”

Herein, we detailed the distributions and distortions of residual stresses in amine-grafted multiwalled carbon nanotubes (MWCNTs)/binary resin composites under complex thermomechanical loadings suffered in practical processing or operation, by means of finite element simulation. First, distributions and distortions of residual stresses under coupled extensional–shear loadings were studied. Subsequently, thermal residual stresses were deducted from the thermal analysis, followed by a sequentially structural analysis. It is found that the heat flux has an influence on the magnitude of the thermal residual stresses, but it cannot alter the distribution of the thermal residual stresses. In order to render deep understanding of the microscale behavior in amine-grafted MWCNTs/binary resin composites under thermal loading, for exploring the nature of residual stress variation, the corresponding microscale model is expected to be developed using atomistic simulation, in which the microstructural features of amine-grafted MWCNTs and resin matrix are taken into consideration. The total energy, potential energy, and kinetic energy at different temperature were analyzed as well as the radial distribution function g( r). Weak van der Waals interaction between amine-grafted MWCNTs and resin matrix is indicated and the interactions between amine-grafted MWCNTs and resin matrix reduce and the mobility of chain segments of resin matrix increases with the decreasing temperature.
