ジャーナル フリーIt is well known that a rubber material generally behaves as an electrical insulator and the vapor-grown carbon fiber (VGCF) has excellent electrical conductivity. In our study, we mixed carbon nanofiber (VGCF) into styrene-butadiene rubber, and investigated the relationship between strain and the electric capacitance of vulcanized rubber filled with VGCF, of which the hardness was not changed at all. The electric capacitance of the rubber filled with VGCF increased with the VGCF content, but decreased with the increasing tensile strain. It was confirmed that change rate of the electric capacitance is related to the VGCF contents of the fillers. In order to investigate the relationship between strain and electric capacitance of rubber with VGCF, the rubber composites filled with VGCF is feasible to apply as a strain sensor.抄録全体を表示PDF形式でダウンロード (921K) -

ジャーナル フリーThis paper proposes a numerical approach for predicting the injection-molding process of short-fiber-reinforced plastics using the Moving Particle Semi-implicit (MPS) particle-simulation method. Unlike conventional methods, this approach represents all of the fibers and the resin as particles and automatically analyzes the interaction between the fiber and the resin and the interaction between the fibers. This method can also follow the flow of a specific fiber. The injection molding of short-fiber-reinforced plastics was simulated assuming the thermoplastic resin to be an incompressible viscous fluid and the fibers to be rigid bodies. The numerical result demonstrated that the molding material was unidirectionally reinforced by short fibers since the fibers were rotated and aligned parallel to the flow direction due to the velocity gradient near the boundary. Moreover, the resin was predicted to accumulate at a corner. These results agreed well with previous studies, and the present approach was confirmed. Furthermore, we predicted the accumulation of fibers near a wall due to the velocity gradient, which could not be represented by conventional simulation methods.抄録全体を表示PDF形式でダウンロード (1557K) -

ジャーナル フリーFabrication of CNT-dispersed epoxy under various conditions using the ball milling process is performed as a fundamental research on the application of CNT-dispersed resin to CFRP composites. CNT length in compounds and viscosity of CNT-dispersed resin are measured in relation to process conditions. Viscosity characteristics on CNT-dispersed compounds and relationship between CNT length and viscosity are clarified in this paper.抄録全体を表示PDF形式でダウンロード (1592K)
