“…The resin infusion process has widely been used in industries such as automotive, aerospace, and marine [26][27][28]. The use of nanoparticles as secondary reinforcements is new to large-scale industries and requires complete scientific understanding of their interactions with other reinforcing materials.…”

In this paper, the effects of graphene oxide (GO) nanoparticles on glass fiber composite processing by incorporating them into epoxy resin were investigated. GO was synthesized from graphite powder and was mixed with epoxy resin. Three different GO contents of 0.05, 0.1, and 0.2 wt% were used. Epoxy/GO samples were tested for rheology and cure kinetics to evaluate the effects of GO content on important resin infusion processing parameters. The results show that adding GO to neat epoxy resin increased the viscosity and affected the resin cure reaction by reducing the resin gel time. After that, glass fiber composites were prepared using the resin infusion process. Samples with 0.2 wt% GO result in very slow resin infiltration time with premature resin gelation. A 30 % increase in flexural strength and a 21 % increase in flexural modulus are manifested by adding GO as the secondary reinforcement to glass fiber composites.

“…In the case of the Halcon 2, the key challenge is to manufacture all main components of the aircraft by Vacuum Assisted Resin Infusion (VARI). Other efforts for manufacturing aircraft components in "single step" have become reliable in recent years [11][12][13][14]. Meredith et al [10] have studied the performance versus cost analysis of carbon fiber reinforced plastics (CRFP), for a specific requirement such as specific energy absorption (SEA).…”

“…By comparing autoclave versus conventional oven cures, they were found to have identical SEA, providing a cost benefit for massive production. Another example was reported by Verma et al [11] by analyzing the challenges in a cocured wing test box by vacuum enhanced resin infusion technology (VERITy). They focused on four major technological challenges: 1) selection of materials and optimization of process parameters; 2) design and development of tools; 3) layup of dry layers and assembly preforms; and 4) design of infusion strategy.…”

This work describes the technological and scientific efforts on designing, manufacturing and testing validation for high performance-low cost composite structures for Light Sport Aircrafts (LSA). A Mexican initiative to conceive, manufacture and assembly a Light Sport Aircraft has been developed by using Computational Fluid Dynamics (CFD), Finite Element Analysis (FEA) and Liquid Composite Manufacturing (LCM). These consolidated techniques are used to characterize novel approaches to manufacturing and assembly carbon-fiber based structural components. As large structures are manufactured via Vacuum Assisted Resin Infusion (VARI), impregnation strategies are studied to minimize inner flaws and also to improve the manufacturing time and surface quality of each component. The first case of study, to validate this methodology, involves non-structural components such as the cowling. Control surfaces (ailerons, rudder, elevator and flaps) have been manufactured, each of them having common issues but also unique challenges. As an example, a second case of study, the aileron main beam is analyzed. Furthermore, test portfolio will be developed with the goal to perform 1-to-1 scale mechanical tests for validation in compliance with ASTM standards.

Polymeric composite materials are largely used for small vessels hull fabrication. They have many desired advantages like low weight, good mechanical performance and good resistance to marine environments. Resin infusion is one of the most common manufacture processes used for this kind of application. In this process, injection tubes are positioned above reinforced media inside mold cavity and resin is forced to flow, first, through these tubes. Tube correct positioning is crucial for a fast and free of imperfections (air bubbles or other filling problems) hull fabrication; however, usually, it is not easy to determine best location for them. In this work, a numerical modeling of the resin injection into a small hull vessel was performed using OpenFOAM software. Besides main solver, other three applications were used in current work. Blender was used to build the tree-dimensional hull geometry, Gmsh used to discretize the geometry, creating a regular mesh formed with hexahedra elements and ParaView used in results post-processing. Finite volume formulation combined with the volume of fluid method was used to solve the multi-phase (air + resin) fluid flow. Four sequential simulations were necessary to determine optimized injection procedure. Each simulation represents an enhancement to the previous one correcting problems like void formation. At the end, some theoretical recommendations are proposed and discussed for an optimized injection procedure for small vessels fabrication.
