“…In a similar manner, increased temperature along with increased duration of molding reduced the tensile strength despite insignificant linear effect of the later variable (Figure 4b). According to Xie et al (2019), low temperature of compression molding may lead to insufficient impregnation of fillers and adjacent polymer chains while too high a temperature can lead to degradation. Meanwhile, longer duration could beneficially affected tensile strength due to improved resin flow and better fillers impregnation.…”

“…Nevertheless, long duration molding could be a disadvantage, which may expose polymer to degradation (Campo, 2008), especially in consolidation of UHMWPE containing cellulose nanofiber (CNF) fillers. Appropriate compression molding parameters are essentially needed for polymer diffusion and filler impregnation into the matrix (Xie et al, 2019) while avoiding polymer degradation. Meanwhile, in order to improve its productivity, the shorter duration is imperative for more effective processing.…”

Conventional UHMWPE molding involves long pressure holding duration, nevertheless in the presence of filler such as cellulose nanofiber (CNF), this may contribute to filler degradation. This study optimized the compression molding parameters of UHMWPE/ CNF bio-nanocomposite by using response surface methodology (RSM) in consideration of temperature, pressure and duration as variables. An optimal processing condition of 180°C, 15 MPa, and 20 minutes contributed to more than 80% desirability with tensile strength, yield strength, elongation at break, and Young’s modulus values of 22.83 MPa, 23.14 MPa, 487.31%, and 0.391 GPa, accordingly. Mechanical properties of UHMWPE/CNF bio-nanocomposites molded at optimized processing conditions were comparably similar to those prepared at conventional processing condition, and with the advantage of having shorter processing time. The results presented herewith provides insight towards a more practical approach for UHMWPE/CNF bio-nanocomposites consolidation process.

“…They reported that 40:60 (fiber to resin ratio) as the optimum condition to achieve improved performance in terms of tensile, flexural, and impact behavior of the composite. Xie et al 26 fabricated polyacrylonitrile (PAN)/CF‐reinforced thermosetting polymer using a hot compression technique. Results revealed that optimum conditions for improved performance in terms of tensile, bending and interlaminar shear strength were achieved at 150°C compression temperature, 20 min holding time under a pressure of 50 T, 3.5°C/min cooling rate, and 80°C mold‐opening temperature.…”

In this study, a hybrid manufacturing technique was proposed to fabricate composites of acrylonitrile butadiene styrene (ABS) with Bidirectional woven glass fiber mat (GF)/ABS and GF/Bidirectional woven carbon fiber mat (CF)/ABS. The composites were fabricated using fused deposition modeling 3D printing, followed by hot compression molding, and their flexural, impact, and dynamic mechanical behaviors were examined. Results indicated that composites with GF and ABS combinations had shown the highest maximum flexural strength (64.46 MPa) and impact strength (0.089 J/mm2). The hybrid composites showed intermediate performance between ABS and GF/ABS composites, with higher flexural strain before failure than ABS and GF/ABS. A comprehensive analysis utilizing scanning electron microscopy was carried out to evaluate the adhesion characteristics of the fiber‐matrix interface in impact‐tested samples. Dynamic mechanical analysis showed that GF/ABS composites had offered superior E′, E″, and tanδ than the hybrid configuration. The peak tan delta values obtained from ABS, GF/ABS, and GF/CF/ABS composites were utilized to determine their respective glass transition temperatures. The observed values for ABS, GF/ABS, and GF/CF/ABS composites were 109.65, 69.95, and 71.5°C, respectively. Some potential applications for the composites fabricated in this study could include the development of lightweight and strong components for aerospace or automotive industries.

“…e obtained temperature and pressure results were imported into ANSYS, and ANSYS was used to simulate the heating process of the molding and analyze the stress and strain conditions of the molding, but the optimal pressure and temperature combination have not been fully studied; the best molding process parameters cannot be obtained; orthogonal experiments have not been performed; and the data cannot be further verified. Xie et al [3] carried out an orthogonal experiment to analyze the influence of the four process parameters of forming temperature, forming pressure, dwell time, and cooling rate on the performance of the sheet and determined the best forming process parameters, but the effect of heating time on compression molding was not analyzed and the obtained process parameters were not further optimized. Fujihara et al [4] designed and completed orthogonal experiments in order to obtain the optimum forming process parameters of PEEK.…”
