“…To prepare the pristine laminate with 0% lead nanoparticle, the epoxy mixture was prepared by mixing the resin parts A and B together at 2:1 ratio, then the laminate was manufactured using the vacuum bagging hand layup process described in. 25,26 The laminate was left under vacuum at room temperature for 20 h followed by heating inside an oven at 70°C for 3 h for post curing.…”

This study investigates the effects of two different parameters on the mechanical properties of carbon fiber-epoxy composites. The two addressed parameters are the composite’s exposure to gamma radiation with different doses, and the incorporation of lead nanoparticles with different weight percentages in the epoxy matrix. Unidirectional carbon fiber-epoxy composites are manufactured using the hand layup vacuum bagging process, and they are characterized by tensile tests and scanning electron microscope. The first part of the study entails fabricating composite laminates with different weight percentages of lead nanoparticles, namely, 0wt%, 1wt%, 2wt%, 3wt%, 4wt% and 5wt%. The results show that composites incorporating lead nanoparticles up to 3wt% exhibit monotonically improved tensile strength and Young’s modulus without compromising their ductility. Whereas, degradation of these mechanical properties is observed with increasing lead content beyond 3wt%. For the second part of the study, composite specimens are exposed to different doses of gamma radiation, namely, 0, 25, 50, 75 and 100 kGy. It is observed that the tensile strength, the modulus of toughness and the ductility of the composites improve for radiation exposures up to 25 kGy. However, radiation exposures higher than 25 kGy lead to deterioration in the tensile strength, modulus of toughness and Young’s modulus with negligible effect on the ductility.

“…AM reduces design constraints, resulting in a shorter design and production cycle as well as a quicker fabrication procedure, which produces effective printed products, particularly for mass production and customized goods. It is a widely used processing technique, yet the strength of polymer-fiber composites produced by AM is far lower than that of conventional manufacturing methods such as vacuum-assisted resin transfer molding, injection molding, pre-preg layup, and vacuum bagging in an autoclave [ 2 , 3 , 4 , 5 , 6 , 7 ]. There are various techniques of executing AM; however, Stratasys introduced FDM for the first time, a layer-wise 3D printing technology to fabricate intricate geometrical objects.…”

Additive manufacturing (AM) has arisen as a transformative technology for manufacturing complex geometries with enhanced mechanical properties, particularly in the realm of continuous fiber-reinforced polymer composites (CFRPCs). Among various AM techniques, fused deposition modeling (FDM) stands out as a promising method for the fabrication of CFRPCs due to its versatility, ease of use, flexibility, and cost-effectiveness. Several research papers on the AM of CFRPs via FDM were summarized and therefore this review paper provides a critical examination of the process-printing parameters influencing the AM process, with a focus on their impact on mechanical properties. This review covers details of factors such as fiber orientation, layer thickness, nozzle diameter, fiber volume fraction, printing temperature, and infill design, extracted from the existing literature. Through a visual representation of the process parameters (printing and material) and properties (mechanical, physical, and thermal), this paper aims to separate out the optimal processing parameters that have been inferred from various research studies. Furthermore, this analysis critically evaluates the current state-of-the-art research, highlighting advancements, applications, filament production methods, challenges, and opportunities for further development in this field. In comparison to short fibers, continuous fiber filaments can render better strength; however, delamination issues persist. Various parameters affect the printing process differently, resulting in several limitations that need to be addressed. Signifying the relationship between printing parameters and mechanical properties is vital for optimizing CFRPC fabrication via FDM, enabling the realization of lightweight, high-strength components for various industrial applications.

“…An alternative could be spreading CNTs in the full matrix resin and not only in the interlaminar region. Abdelal et al evaluated vacuum bagging process to prepare carbon fibre/CNT composites but they found negligible improvements of the strength which were covered by data scattering [6]. In the same year, Yourdkhani et al started with the consideration that effective dispersion of CNTs in the polymer matrix of fibrereinforced composites is challenging due to the re-agglomeration and filtration of CNTs that occur during liquid processing [7].…”

Carbon fibre reinforced (CFR) laminates were manufactured by prepreg lay-up and deposition of interlaminar carbon nanotubes (CNTs). An easy and innovative manufacturing procedure was used. CNTs were separated in solvent by ultrasonication, and poured on the woven fabric prepreg. Solvent evacuation was performed at low temperature, and dry functionalized prepregs were used for composite lamination. Laminates were cured by compression moulding on a heating plate. Peeling tests, differential scanning calorimetry (DSC), and dynamic mechanical analyses (DMA) were carried out on multiply samples with and without 1 wt% of interlaminar CNTs. Results show that the glass transition temperature of the resin matrix reduces because of the interaction with CNTs. Nevertheless, peeling strength shows 10% increase at room temperature.
