“…The logarithmic thickness strain of GFRTP stamp formed components under various experimental runs has been plotted ( Figure 11). Compared to the initial blank thickness, the components formed under high die temperature conditions were up to 22% thinner, whereas the low die temperature formed components were up to 16% thicker at the flange portion [8] . The reason is that the high temperature difference between the heated blank and die, made the blank to solidify at the faster rate and led to the formation of a severe wrinkling on the surface of components, which in turn increased the flange thickness.…”

“…The ANOVA details of weighted grey relational grade for the four cases are presented in Tables 6 and 7. The analysis clearly shows the die temperature as the most significant factor [8] followed by the blank holder force and blank temperature for all the four cases, in affecting the performance characteristics of dome-shape formed components. With increase in the weightage of forming ratio, the contribution of die temperature increased from 37.5% to 77.2%, whereas the contribution of blank holder force and blank temperature decreased from 50% to 17.9% and from 3.9% to 2.2% respectively.…”

“…These are illustrated in Figure 5. The process parameters were chosen on the basis of findings seen in literatures [7,8,24,25] . Before taking up the stamp forming process, each circular blank was pre-heated to the definite blank temperature in the oven and then transferred to the steel die.…”

“…They observed the larger significance of wrinkles in the wrap direction of the composite domes in contrast with the weft direction. The influence of four parameters on the degree of crystallinity, shear strength, and part thickness were evaluated by Lessard et al [8] . They found a notable contribution on part consolidation made by the stamping pressure and mold temperature.…”

Advanced fabric reinforced polymer composites find extensive applications in aerospace and structural fields due to their high mechanical properties. A novel stamp forming technique finds extensive use in the hemispherical forming of thermoplastic composites. This study investigates the influence of stamp forming parameters on the formability of thermoplastic composite using Taguchi's robust design and grey relational analysis. Taguchi's orthogonal array was used for designing the forming experiments. Responses such as forming ratio and logarithmic thickness strain were considered for the assessment of sheet formability through single and multi-response optimization. Analysis of variance was used for the determination of the contribution of each parameter on formability and it was identified that the die temperature acts as a prominent factor, followed by blank holder force and blank temperature. The confirmation test was conducted at optimum parameter levels and the obtained experimental grade was seen within the confidence interval of the predicted value.

“…Temperature only has a little effect on the impregnation. In general, the processing temperature of continuous carbon fiber reinforced PEEK composites can be optionally selected from 380°C to 420°C . In this research, 400°C is chosen as the processing temperature.…”

In order to manufacture excellent CCF300/PEEK composites, a comprehensive study on controlling porosity of CCF300/PEEK composites was investigated by optimizing the impregnation parameters. Four kinds of PEEK with different melting flow rates (MFR) were employed to study on their rheology behavior and reveal the processing characteristics. The results showed that the viscous flow of PEEK has a higher dependence on the processing pressure than temperature. Furthermore, PEEK rheology behavior was employed to assist the optimization of impregnation parameters. PEEK powders were coated on both sides of single layer CCF300 by a preheating process, and then the semi‐impregnated forms were stacked layer by layer to manufacture CCF300/PEEK composites. An optimized impregnation prediction model was established and verified, showing a pretty effective prediction about pressure and holding time at a certain temperature to control the porosity and achieve the full impregnation. Afterwards, the well‐impregnated CCF300/PEEK composites were evaluated by their compressive performance, flexural performance and interlaminar shear performance, showing good interfacial and interlaminar bonding to resist the propagation of cracks.

Thermoplastic resins have some advantages in terms of recycling and speed of manufacture. In particular, the thermostamping process leads to short cost‐efficient manufacturing cycles. Consequently, various industrial sectors—especially the automotive industry—have shown growing interest for composite materials made of continuous fiber and thermoplastic matrix and also in their manufacturing processes. Thermoforming of composites is a complex process, conditioned by a number of important phenomena and parameters. For instance, a defect‐free process depends on the temperature conditions, material properties, plies orientation, speed of the process, loads on the tools, and on the blank holders, and so on. Therefore, the development of a good quality composite thermoforming process can be difficult. Numerical simulation of the thermoforming process can provide an initial validation of the process and a determination of suitable parameters. This avoids the time‐consuming “trial and error” process development stage. The objective of this article is to present the elements necessary for the modeling and simulation of the thermoforming process of composites with continuous fibers and thermoplastic matrix. The article also presents the mechanical tests necessary to determine the characteristics of prepregs during thermoforming: the bias‐extension test (in‐plane shear) and the cantilever‐bending test.
