High-performance thermoplastic composites based on semipregs of poly(phenylene sulfide) (PPS) reinforced with carbon fiber (CF) have been widely used in the aerospace industry due to their excellent mechanical properties and thermal stability.In this work, CF/PPS laminates were processed by hot compression molding. The processing parameters (pressure and temperature of processing) were investigated as well as the effect of the number of semipreg layers. The neat PPS matrix and CF/PPS semipreg were evaluated by rheological and thermal properties, respectively, to verify the best processing temperature for the CF/PPS composite laminates. The CF/PPS laminates obtained were inspected by ultrasound and differential scanning calorimetry analyses, and then the standardized specimens were prepared. The mechanical properties were evaluated by tensile test and interlaminar shear strength (ILSS) tests. Morphological characteristics of fracture surfaces also were analyzed by scanning electron microscopy. The ultrasound inspections showed differences among the processed laminates with the presence of defects mainly around the edges of samples. Based on ultrasound maps, the worst regions of laminates were discharged and not used to cut the specimens utilized in the mechanical characterization. Thermal, mechanical, and morphological analyses of the six laminates processed with different consolidation cycles did not show significant differences, showing good CF-PPS matrix interface and similar results of crystallization ($23%), tensile strength (776-858 MPa), and ILSS (59-68 MPa).

“…Lee et al 6 thermoformed glass fiber-reinforced polypropylene composites with different cooling rates and investigated the related mechanical properties. Han et al 7 showed that the optimal thermoforming conditions for carbon fiber-reinforced polyphenylene sulphide laminates could be obtained according to their effects on the finished dimensions of V-shaped parts. The effect of the stacking sequence of glass fiber-reinforced polypropylene composite laminates was studied to prevent wrinkling in the deep drawing process.…”

The spring-in behavior of woven carbon fiber/polycarbonate thermoplastic composite is investigated by both the experiment and simulation ways. These thermoplastic composite plates are thermoformed into V-shaped structures, and the final bending angle is measured after demolding. In the finite element simulation to describe the thermoforming and spring-in behavior of the composite, the discrete approach is adopted to simulate the behavior of woven carbon fabric and combined with a resin model. The results from both the experiment and the simulation indicate the spring-in behavior of this thermoplastic composite. For [(±45)]6 blanks, the spring-in angle is around 2.60° for a 60-degree V-shape and around 1.72° for a 90-degree V-shape. For [(0/90)]6 blanks, the spring-in angle is around 2.38° and 1.19° for 60-degree and 90-degree V-shapes, respectively. The [(±45)]6 blank always has a slightly higher spring-in angle than the [(0/90)]6 blank, even though the difference is small. The finite element results show 6% to 12% differences with the experimental values if the spring-in angle is used, and the error is less than 0.6% when the bending angle is compared. By using the present finite element analysis, the results indicate that the stacking sequence could have an evident effect on the spring-in angle, and symmetric laminates have less spring-in effect as compared to their unsymmetric counterparts.

“…The related reports are mostly limited to the hemispherical, C-shaped, L-shaped, or other components with simple structure. For example, Han et al 9 thermoformed V-shaped parts via out of autoclave thermoforming experiments, considering that selecting an appropriate mold temperature was very important to the forming precision and performance of components. Brauner et al 10 fabricated fiber-reinforced thermoplastic L-shaped components in short cycle times (less than 2 min) and believed crystallization out of sync in the surface and inner of components was the causes of demolding deformation.…”

The forming process is the core factor to control the quality of thermoplastic composite components. In this paper, the common I-stiffened structures in the aerospace field were taken as the research object, and the forming process scheme was designed. Based on the prefabrication of C-shaped parts, the I-stiffened structures were prepared by the compression molding process. The influence law of molding temperature on the quality of the prefabricated C-shaped parts was explored. The time dependence of the PEEK melt viscosity was tested to provide the basis for the optimization of forming process parameters of I-stiffened structures. The influencing mechanism of thermoplastic composites repeatedly forming to the bonding strength of remelting interface was studied. The results show that repeated forming would lead to polymer aging and result in low bonding strength at the remelting interface of the I-stiffened structures. Optimizing the forming process could effectively reduce the aging of materials and improve the bonding strength of the remelting interface and overall mechanical properties of components. The research provides technical guidance for the manufacturing of complex thermoplastic composite components, especially the influence mechanism of the forming process on the bonding strength of remelting interface.
