Impregnation Process

Carbon fabric-reinforced thermoplastic (CFRP) composites, fortified with carbon fiber prepreg and epoxy base materials, have been mainly used for body parts for weight lightening, advanced high strength, and impact absorption In the current automotive industry However, as recycling of the composite material is required, attempts have been made to manufacture body parts using a thermoplastic polymeric material as a base substance. In order to produce various types of body parts by impregnating a liquid thermoplastic material into carbon fabric preform in methods of manufacturing a carbon fiber-reinforced thermoplastic composite material (CFRTP), it is important to understand the effect of the impregnation process parameters (time, temperature, pressing force) on the mechanical properties of the composite material. Therefore, in this study, the influence of impregnation process parameters on the mechanical properties of CFRTP is proposed. In addition, this paper presents the problems and solutions when polymeric materials are impregnated in carbon fabric.

Carbon Fiber Reinforced

Promising carbon fiber-reinforced thermoplastic (CF/polyetherketoneketone (PEKK)) composites were fabricated by the state-of-the-art technology known as “Automated Fiber Placement.” The mechanical properties of CF/PEKK were evaluated for four different postprocessing methods: in situ consolidation, annealing, vacuum bag only (VBO), and hot press (HP). The evaluation was performed by narrowing down the relevant processing parameters (temperature and layup speed). Furthermore, the void content and crystallinity of CF/PEKK were measured to determine the effect of these postprocessing processes. The HP process resulted in the best quality with the highest interlaminar shear strength, highest crystallinity degree, and lowest void content. The second most effective method was VBO, and annealing also realized an improvement compared with in situ consolidation. The correlation between the postprocessing method and the void content and crystallinity degree was also discussed.

Constitute Model

Owing to the excellent mechanical properties and formability of carbon fiber reinforced thermoplastic composites, this composite has been applied in car industry. The static and dynamic mechanical properties of the composites are investigated under strain-rate from 0.001/s to 50/s. The experimental results show that the elastic model and tensile strength increase with the increase of strain rate, and show that the composite has remarkable rate-hardening effect. A constitute model that including rate-dependent effect is applied to present the strain-stress curve of the composite. The constitute model provides accurate constitute function for finite element analysis of the composite.. The microstructure of the composite is also investigated with scanning electric microscope, and the failure modes are discussed. The investigation provides the basis for engineering application of the composite.

In situ consolidation of thermoplastic composites by Automated Tape Placement (ATP) is challenging. High quality ATP grade pre-preg material and tape head equipped with an efficient heat sources like lasers offer an opportunity towards high deposition rates and improved mechanical properties of composite materials. In this study uni-directional carbon fiber/ polyphenylene sulfide (UD tape prepreg CF/PPS), carbon fiber/polyetheretherketone (UD tape prepreg CF/PEEK) as well as blend of carbon fiber/polyetheretherketone/polyphenylene sulfide (UD tapes prepregs CF/PEEK/PPS) laminates are compared in terms of their properties after beeing processed by ATP technology. CF/PPS, CF/PEEK and blend CF/PPS/PEEK laminate specimens were processed using in-situ laser-assisted ATP (LATP) process. LATP processing parameters used in this study were chosen based on a preliminary trials; the results provide a basis for refinement of these parameters and prepreg material with an optimal and balanced set of final mechanical properties. This study showed an attempt how to manage the processing parameters for LATP process and to obtain composite materials with tailored properties. The process for production of thermoplastic plates with LATP head in general is a process that is governed by many parameters such as: laser power, angle of incidence, roller pressure and temperature, placement speed, tool temperature, then types of the roller material and the tool material. These parameters are not subject of discussing in this paper; they are kept constant, and the goal of the paper is to manage the crystallinity level within the composite thermoplastic material during annealing step at different temperatures after LATP process. Also, the void content during the production process could be controlled. More particularly, the authors showed that composites based on PPS matrix manufactured with LATP process possess higher flexural strength, with less void content compared to samples based on PEEK matrix. These samples showed also higher crystallinity after annealing step.

Poly(ethylene-2,6-naphthalene) (PEN) is one of the most important engineering polymers with high performance. However, the effects and foaming behavior of carbon fiber (CF)-reinforced PEN (CFRPEN) remain to be explored. In this study, PEN was used as the matrix for CF-reinforced composites, and its foaming behavior and mechanical properties were investigated. High mechanical properties can be evaluated through comparison with other similar CF-reinforced thermoplastic composites. A fabrication method to generate lightweight and high-strength CFRPEN composites is hence proposed.

This study focused on the faint interface bonding between carbon fiber (CF) and poly(phthalazinone ether ketone) (PPEK) thermoplastic, a multistage hybrid interface layer was constructed via the condensation reaction of N-[3-(Trimethoxysilyl)propyl]-N,N,N-trimethylammonium chloride (KHN+) and the electrostatic adsorption of graphene oxide (GO). The influence of the contents of GO (0.2 wt%, 0.4 wt%, 0.6 wt%) on the interfacial properties of composites was explored. FTIR, Raman spectra, XPS tests indicated the successful preparation of CF-KHN+-GO reinforcements. The multistage hybrid interface layer significantly increased fiber surface roughness without surface microstructure destruction. Simultaneously, polarity and wettability are remarkably improved as evidenced by the dynamic contact angle experiment. The interlaminar shear strength (ILSS) and flexural strength of the CF/PPEK composites with 0.4 wt% GO (CF-KHN+-4GO) were 74.57 and 1508 MPa, which was 25.2% and 23.5% higher than that of untreated CF/PPEK composite, respectively. Dynamic mechanical analysis proved that CF/GO/PPEK composites have excellent high-temperature mechanical properties. This study furnishes an unsophisticated and valid strategy to build an interface transition layer with a strong binding force, which would offer a new train of thought in preparing high-performing structural composites.
