Computer-aided design and modeling of composite unit cells

An eigenfunction expansion–variational method in prediction of the transverse thermal conductivity of fiber reinforced composites considering interfacial characteristics

“…The periodic composite models provide useful limiting values of interacting inclusions from entirely disorder (random) to order. At the same time, the so-called composite design is generally a design of periodically distributed unit cells of a composite [10]. Gu and Liu [11] discussed the thermal conductivity of periodic composite media with contact resistance by applying a generalized Rayleigh identity.…”

Uniform modification of carbon fibers surface in 3-D fabrics using intermittent electrochemical treatment

“…Therefore, it is the key factor to get a sufficient infiltration and adhesion between the fibers in the fabric and the matrix resin. Many investigations, which have been carried out for this purpose, were primarily focused on the improvement of the fluidity of matrix resin [3,4], optimization design of the fabrics preform [5][6][7] and the simulation of the resin flow model [8,9]. Moreover, the fiber surface property was also an important factor for a good interface adhesion in 3-D fabrics composites.…”

Vibration modal analysis of three-dimensional and four directional braided composites

“…According to the structural characteristics of 3D4d braided composite, a variety of microscopic models were presented for mechanic analysis [20][21][22]29,30]. The inner structure of 3D4d braided composite is shown in Fig.…”
