“…The composite laminate was prepared by resin transfer modeling process using epoxy resin (TDE-86, Tianjin Jingdong Co. Ltd, Tianjin, China). Generally speaking, the fiber volume fraction of carbon fiber felt reinforced composites was less than continuous fiberreinforced composites [30]. Piat et al [16,31] predicted the effective elastic properties of the CVI-densified carbon felts, and the fiber volume fraction is 12%.…”

In this study, the three-dimensional finite element models of carbon fiber needled felt reinforced composites were built by using the embedded element technique and the virtual yarn method. Three sizes of samples for carbon fiber needled felt reinforced composites were designed and prepared. The tensile properties were investigated by experiments and theoretical methods, and the influences of sample size on tensile modulus were discussed. The results showed that, the longitudinal tensile moduli of carbon fiber needled felt reinforced composites decreased with the increase of sample size. Compared with the rule of mixtures and the inclusion theory, the longitudinal tensile moduli obtained by finite element method were closer to the experimental values. In addition, the transverse tensile moduli obtained by finite element method were greater than that obtained by the rule of mixtures and the inclusion theory. That was due to the orientation of some fibers had a proportion along the thickness. It was concluded that, these three-dimensional finite element models can be used to investigate the elastic properties of carbon fiber needled felt reinforced composites with different sizes.

“…A tighter fiber arrangement requires a higher pressure (20 MPa) to effectively squeeze the resin, while a pressure of only 3 MPa is required for a looser fiber arrangement. (8) In this study, we developed a carbon fiber current collector for use in proton exchange membrane fuel cells. The current collector has high conductivity, corrosion resistance, and mechanical strength.…”

The main aim of this study is to use a carbon fiber composite board to replace the traditional graphite board. Because a carbon fiber composite has high mechanical strength and corrosion resistance and other desirable properties, we fabricate it into a current collector for use in a fuel cell. We use phenolic resin and flake graphite powder combined with carbon fiber plain weave to fabricate the carbon fiber composite current collector, which is carbonized in a high-temperature furnace at 800 °C. In this method, the resin, which has poor conductivity, is removed to increase the conductivity of the current collector. The electrical conductivity is measured using a fourpoint probe surface resistance machine and the flexural strength is measured using a universal material testing machine. In addition, the same characteristics of carbon fiber composite materials fabricated with different carbonization times are then discussed. Finally, the carbon fiber composite current collectors are assembled in single cells for performance testing.
