Summary: Transverse impregnation variants of LCM processes, including RTP and CRTM, show fast fill times and the model developed in this study simulates these processes accurately, considering factors like process time, fluid pressure, stress, and fiber volume fraction distribution. Assumptions like quasi-steady flow and uniform through-thickness deformation lead to significant errors in manufacturing process predictions, especially for transverse processes involving direct tool compaction of the fiber preform.

Summary: Continuous fiber tow reinforcements in hybrid-molded composite structures have the potential to replace high production volume metal components, but further research on design variables is needed. Testing representative structures with automotive component features, different material combinations and reinforcement content were evaluated. Tow reinforcements significantly reduced warpage and showed a potential strength increase of 340% in tensile loading. However, the performance in three-point bend tests was influenced by the overmolding material, and it is recommended to use high strain to break overmolding materials to prevent premature cracking.

Summary: Electrothermal processes were investigated in pyroresistive composites of high-density polyethylene with carbon black and carbon fibers. The kinetic heating curves showed an exponential dependence with a heating rate constant for each composite. Equilibrium temperature was reached after a short heating time, and decreased with the presence of positive temperature coefficient of resistance (PTC) effect. The composites exhibited self-regulating capability and the equilibrium temperature depended on the applied voltage and electric power with different relationships. An application of using HDPE-CB composite as a heating element for resistance welding was demonstrated.

Summary: This study aimed to fabricate hybrid polymer composites using ABS polymer, GF and CF by combining fused deposition modelling and hot press moulding technique. The mechanical and thermal properties of the composite specimens were characterized. The tensile strength of GF/ABS and GF/CF/ABS composites was significantly higher than that of virgin ABS. GF/ABS composites showed improved thermal resistance with a final residue of 42.36%, followed by GF/CF/ABS hybrid composites. Thermomechanical analysis revealed the thermal expansion coefficient in the order: ABS > GF/ABS > GF/CF/ABS. The entropy obtained from the DSC curve was higher for the composites compared to ABS. These ABS-based composites can be widely used in structural parts of automobiles, aircrafts, and shipping vessels.

Summary: Recycling and reutilization of industrial waste is an effective way to reduce land pollution and achieve a green environment. This study utilized waste SiC grinding wheel as filler material to develop epoxy glass fibre composite, and investigated its machinability using abrasive water jet machining. The results indicated that the transverse speed and standoff distance had significant influence on the material removal rate and kerf width. The optimal parameters for achieving high material removal rate and low kerf width were found to be a transverse speed of 30 mm/min, a standoff distance of 2 mm, and a water pressure of 220 bar.
