Unidirectional carbon fiber (CF) / Polyamide 6 (PA6) composites were prepared by stacking fabrics method. Due to the effect of the textile structure and rough surface of PA6 fabrics, slipping of carbon fibers (CFs) during the stacking process was prevented and uniformity of impregnation was improved. Meanwhile, the usage of PA6 fabrics resulted in the minimum level of void content of composites, which improved the mechanical properties of composites. Additionally, the void content of materials was associated with the mechanical properties of composites. The flexural strength of composite reached 819.58 MPa when its void content was 3.49%. Moreover, a model based on Darcy’s law was developed to simulate the impregnation behavior of PA6 in CFs which was made by stacking fabrics method. The resin flow was observed by using optical microscopy. The evolution of void content in composites was related to the processing parameters (holding time, processing temperature and processing pressure).The comparison between the experimental and simulated data showed that the model was reliable to describe the impregnation process.

“…Furthermore in comparison with PAN-CF, the conversion percent of pitch precursor to carbon fiber is high and it does not require a long stabilizing process during making CF. The high performance/ cost ratio of pitch-CF composites makes them highly attractive in the field of short CF reinforced composite materials, especially in mass-production operation [13][14][15][16][17]. The performance of Pitch-CF reinforced carbon composites has been studied by Liedtke and Huettinger [18,19].…”

Thermal and mechanical properties of different short carbon fibers (CF) reinforced polyether-ether-ketone (PEEK) composites are investigated, where CF is made from polyacrylonitrile (PAN-CF) and pitch (Pitch-CF). The thermal properties of both composites are studied using differential scanning calorimetry (DSC) and dynamic mechanical thermal analysis (DMTA). The crystallinity of PEEK increases with the content of PAN-CF, but it is independent of Pitch-CF content. At the isothermal condition, the crystallite rate of Pitch-CF/PEEK composite is faster than that of PAN-CF/PEEK composites. Dynamic tensile modulus of PAN-CF/PEEK increases with the CF content. An increase of glass transverse temperature with an increase in CF content is found in PAN-CF/PEEK, but not in Pitch-CF/PEEK. The fracture toughness of PAN-CF/PEEK composites increases with CF contents; whereas it remains the same value for Pitch-CF composite. The fracture surface of both composites is analysed using scanning electron microscopy.

The effects of different processing conditions (pressure, holding time and temperature) on the impregnation/consolidation quality of CF/PEKK composite were investigated using compression molding process. Microscopic investigation of cross-sections, density measurements and flexural mechanical properties were used to examine the quality of impregnation and consolidation. A qualitative model to describe the impregnation and consolidation process of this material was developed. The model predicts the variations of void content during consolidation as well as the holding time, moulding temperature and pressure required to reach full consolidation. Good agreement between theoretical predictions and experimental data was achieved. Optimum processing conditions can be determined based on selected void content.
