Mechanical Properties of Layered-Carbon Fiber Reinforced with Vacuum Infusion Process

Research on material engineering is widely developed in the precursors, composition of the material, and technique to create a composite. The layering and vacuum infusion resin are the developing technology to create the composites with the new characteristics and properties. This experiment is intended to find out the characteristics of layering carbon fiber reinforced by resin and is molded with vacuum infusion technique. The specimens of this experiment is layered-carbon fiber composites determined in three, four, five, six, and seven layers. The precursors of 220 and 240 carbon fibers are the main material of the composites. The tests conducted to the specimens are bending and tensile tests. The both tests are treated to reveal the mechanical properties of the composites. The least layers of 220 and 240 carbon fiber result the highest value of bending test, but the most number of carbon fiber layers show the opposite value. The results are reverse in the tensile test. The highest value of the tensile test is achieved by the most layers of carbon fiber, while the lowest value is in the least layers. This result is almost the same with the strain-stress, but overall the graphic is similarly increase to the most layers. Deduction achieved in this experiment is that the number of layers in the carbon fiber composites is significantly influencing the mechanical properties of the composite.

The mechanical properties of three phase nano-modified carbon fiber reinforced polymeric composites (CFRP) fabricated using Heated Vacuum Assisted Resin Transfer Molding (HVARTM) is investigated. Eight layers of carbon fiber plain weave mats were stacked in quasi isotropic layup and Epoxy 862 resin (non–modified and modified with Boron Nitride Nanoparticles (BNNPs)) was used. For mechanical properties characterization, three ASTM tests were performed. These tests included Tension Test (ASTM D3039), Compression Test (ASTM D6641) and Flexural Bending Test (ASTM D7264). The behavior of control and nano-modified composite laminates were compared. Results indicated that even small percentage of Boron Nitride Nanoparticle can significantly affect mechanical behavior of CFRP as well as progressive failure mechanisms.

This study investigates the transverse section property of unilateralism carbon fiber reinforced resin matrix composites in shot-beam shear conditions. Carbon fiber composites made in China and a composite T300 made in Japan were tested. Analysis was made for these composites on the shear strength data and the appearance of macro characters. Possible sequence of failure initiation and propagation of each composite was proposed by the SEM with optical microscopy observations of failed specimens. The result revealed that the interfacial property is the most important factor responsible for the failure mode of unilateralism carbon fiber composites, and the Chinese carbon fiber composites need to improve the interfacial property for wider use.

The prepreg process among the CFRP (Carbon Fiber Reinforced Plastic) forming methods is the short term of ‘Pre-impregnation’, which is widely used for aerospace composites that require a high quality property such as a fiber-reinforced woven fabric, in which an epoxy hardening resin is impregnated. the reality is, however, that this process requires continuous researches and developments for its commercialization because the delamination characteristically develops between the layers when a great weight is loaded from outside. to supplement such demerit, three lamination methods among the prepreg lamination methods of CFRP were designed to minimize the delamination between the layers due to external impacts. Further, the newly designed methods and the existing lamination methods were analyzed through a mechanical characteristic test, tensile test and infrared thermal device during the tensile tests, to obtain a better property than the existing lamination methods. the tensile test result showed that the newly designed three lamination methods, i.e. Roll, Half and Zigzag lamination methods, appeared superior to the Play lamination method in the aspects of the strength and strain. The strength of the Zigzag lamination method, which was the highest, was confirmed as being improved by about 20% than that of the Ply method.

Carbon Fiber Reinforced

Fiber reinforced composites offer exceptional directional mechanical properties, and combining their advantages with the capability of 3D printing has resulted in many innovative research fronts. This review aims to summarize the methods and findings of research conducted on 3D-printed carbon fiber reinforced composites. The review is focused on commercially available printers and filaments, as their results are reproducible and the findings can be applied to functional parts. As the process parameters can be readily changed in preparation of a 3D-printed part, it has been the focus of many studies. In addition to typical composite driving factors such as fiber orientation, fiber volume fraction and stacking sequence, printing parameters such as infill density, infill pattern, nozzle speed, layer thickness, built orientation, nozzle and bed temperatures have shown to influence mechanical properties. Due to the unique advantages of 3D printing, in addition to conventional unidirectional fiber orientation, concentric fiber rings have been used to optimize the mechanical performance of a part. This review surveys the literature in 3D printing of chopped and continuous carbon fiber composites to provide a reference for the state-of-the-art efforts, existing limitations and new research frontiers.
