Long Carbon Fiber

In the present study, the difference of long carbon fiber reinforced thermoplastic (C-LFT) depending on the type of polymer resins at the same carbon fiber content (30 wt.%) was compared. The different types of C-LFT were made using five polymer resins such as polyamide 6, polyamide 6,6, polycarbonate, high density polyethylene and polypropylene. Tensile test, flexural test, and unnotched Izod impact test were carried out and the cause of difference in the mechanical properties was considered by analyzing the adhesion characteristics. Fracture appearance and work of adhesion between the fiber and the resin were observed. In addition, the difference and its cause in electromagnetic interference shielding effectiveness (EMI SE) was investigated. From the results, the polyamide 6 is most appropriate to the carbon fiber among the samples in the aspects of interfacial shear strength and fiber dispersion.

Unidirectional carbon fiber reinforced polyamide 6 (CF/PA6) laminates after tensile tests exhibited two different types of fracture modes, namely, splitting and step-like. In this study, the mechanical properties and fracture behavior of the unidirectional CF/PA6 laminates were simulated and analyzed by using finite element simulation of a tensile test. The simulations considered the actual deformation and damage mechanism (matrix plastic deformation, stochastic fiber fracture, and interfacial debonding between the fiber and the matrix) experimentally observed in previous research. Results of the numerical simulations were in good with the experimental stress–strain curves. Moreover, the above-mentioned two types of fracture mode were well simulated by changing the interfacial properties. The simulated results showed that the unidirectional laminates with weak interface properties exhibit the splitting fracture mode. Meanwhile, the unidirectional laminates with strong interface properties show the step-like fracture behavior.
