“…[ 10–18 ] Currently, thermosetting epoxy resins are most often used for CFRP tendons. [ 19–21 ] However, the brittle nature of thermosetting polymers such as epoxy is an important issue that makes them less viable for certain applications. Conversely, carbon‐fiber‐reinforced thermoplastic matrix composites (CFRTP) can potentially be postformed and recycled, but their manufacturing is usually an energy‐intensive process due to the high temperatures and pressures necessary for impregnating high‐molecular weight polymers.…”

Hybrid carbon/glass composite rods consisting of unidirectional polyacrylonitrile (PAN)-based carbon fiber (T700SC), braided E-glass fibers, and thermoplastic epoxy matrix were fabricated with differing carbon/glass ratios (24K1P, 24K2P, and 24K3P). The cross-sectional morphologies of the hybrid rods were observed using a digital microscope. Tensile properties and fracture behavior of the hybrid rods were investigated over a range of temperatures: −50 C, 0 C, 23 C (RT), 50 C, and 80 C. The tensile modulus and strength increased with increasing carbon fiber volume fraction, but decreased with increasing temperature. The Weibull statistical distribution of tensile strength for the hybrid rods was examined. The Weibull modulus increased with increasing tensile strength and decreasing void volume fraction of the hybrid rods. A Curtin-type global load-sharing model was applied to the hybrid rods to predict mechanical properties at different temperatures.

“…Mujika et al further conducted a series of experiments to test flexural, tensile and compressive modulus [14]. For unidirectional carbon fibre composites, the compressive strength was measured by conducting three-point bending tests [15]. Theoretical models were proposed to analyze the normal and shear stress distributions during three-point bending tests [16].…”

Carbon fibre composite rod (CFCR) has been widely used in Aluminum Conductor Composite Core (ACCC) conductor. The mechanical properties of CFCR are related with the safety of electric power supply. The mechanical properties of CFCR are mainly determined by volume fraction of carbon fiber. Therefore, it is necessary to analyze the effect of carbon fiber fraction on the mechanical behavior of CFCR. The relationships between carbon fiber fraction and mechanical properties help to the design of ACCC conductor. This paper presents a finite element model (FEM) to analyze the mechanical properties of carbon fibre composite. The mechanical behaviors of CFCR for different carbon fiber fractions were simulated by using FEM. Based on the simulated results, the effects of carbon fiber fraction on stress and strain of CFCR under pure bending loading were revealed.

Carbon fibre composite rod (CFCR) is an important part during the design of Aluminum Conductor Composite Core (ACCC) conductor. CFCR is used to improve the bearing capacity in order to make sure the safety of electric power supply. The flexural failure of CFCR could lead to the outage of electric power. Therefore, it is important to investigate the flexural behavior of CFCR. The diameter of CFCR and the diameter of wheel have a great effect on the flexural failure of CFCR. This paper presents a finite element model (FEM) to analyze the stress in CFCR under flexural loading. Based on the proposed FEM, the effect of diameter ratio on the flexural stress of CFCR is analyzed. Using the calculated results, the variation of flexural stress with the diameter ratio is obtained. These conclusions would help to design Aluminum Conductor Composite Core (ACCC) conductor.
