In this research, an experimental investigation of the microstructural, viscoelastic, and flexural properties of glass/carbon hybrid Fiber Reinforced Polymer (FRP) composites consisting of two different types of weaves (plain and twill) was carried out. The hybrid composites were manufactured by using the VARTM technique. The scanning electron micrographs showed that the hybridization resulted in a significant improvement in fiber-matrix adhesion of the hybrid composites compared to the pure glass fiber reinforced polymer (GFRP) composites based on plain weave glass fabrics, whereas the best fiber-matrix adhesion was observed in carbon fiber reinforced polymer (CFRP) composites. The synergistic effect due to hybridization lead to substantial improvements in the dynamic mechanical and flexural response of the manufactured composites. The hybrid composites exhibited a 149% increase in flexural strength, and a 144% increase in the flexural modulus compared to the GFRP composites, and an increase of 109% in the average value of the storage modulus at three different frequencies (1 Hz, 5 Hz and 10 Hz) compared to the GFRP composites. Whereas, the highest values were observed for pure CFRP composites for both flexural strength and modulus. A positive hybridization effect was also confirmed by the higher experimental values compared to the estimated results calculated by using the Rule of hybrid mixtures (RoHM). Due to higher fiber volume content, the GFRP exhibited the highest thermal stability compared to other specimens.

AbstractThe unmodified and nano-SiO2modified glass fiber reinforced polymer (GFRP) composites were prepared by the hot-compression molding process to investigate the effects of nano-SiO2on the mechanical and hygric properties of the GFRP composites. The results indicate that the nano-SiO2modification results in an increase of 9.7% and 7.9% in the tensile and flexural strength of the GFRP composites, and a decrease of 10.6% in the interlaminar shear strength (ILSS). The maximum swelling of the unmodified GFRP is 2.6 times as that of the nano-SiO2modified GFRP. The normalized-ILSS decrease of the nano-SiO2modified GFRP is only 12% after 138 days aging, while that of the GFRP reaches 31%. After 95-days hygric-aging, the decrease of the normalized flexural strength is 15.3% for the GFRP, while the normalized flexural strength of the nano-SiO2modified GFRP still maintains an increase of 5.0%. It is concluded that the nano-SiO2particle could improve the mechanical and hygric properties of the GFRP composites.

Out Of Plane

Glass fiber reinforced polymer (GFRP) composites are promising alternatives for the traditional carbon steel pipes used in the oil and gas industry due to their corrosion and chemical resistance. However, the out-of-plane mechanical properties of GFRPs still need further improvement to achieve this goal. Hence, in this work, two methods combining either vacuum mixing or spray coating with vacuum-assisted resin infusion were studied to fabricate graphene nanoplatelet (GNP)/GFRP hybrid composites. The former method resulted in a severe filtering effect, where the GNPs were not evenly distributed throughout the final composite, whereas the latter process resulted in a uniform GNP distribution on the glass fabrics. The addition of GNPs showed no modest contribution to the tensile performance of the GFRP composites due to the relatively high volume and in-plane alignment of the glass fibers. However, the GNPs did improve the flexural properties of GFRP with an optimal loading of 0.15 wt% GNPs, resulting in flexural strength and modulus increases of 6.8 and 1.6%, respectively. This work indicates how GNPs can be advantageous for out-of-plane mechanical reinforcement in fiber-reinforced composites.

Nanoclay Content

This paper presents a study on the flexural properties of glass fiber reinforced polymer composites. The epoxy-nanoclay resin was milled using a three roll mill machine to produce exfoliated structure nanocomposites. The fiber laminates specimens were manufactured by vacuum bagging system. These specimens were tested in the three point bend configuration following the ASTM D7264. The flexural modulus, flexural strength and strain to failure were then determined based on the flexural test results. The results showed that flexural modulus and flexural strength increases when a certain amount of nanoclay was included in the resin system. A maximum of 80% and 37% improvement of flexural strength and flexural modulus, respectively, were found at 5 wt% nanoclay content when compared to the neat GFRP composite. The improved properties of GFRP composites were achieved mostly due to an increase on the interfacial surface areas as well as a well-dispersion of nanoclay in the GFRP composite system. The fracture surfaces of specimens after flexural test were observed under FESEM. The results showed that the compressive failure region in the fiber was a dominant failure mechanism of the specimens due to a large compressive area on the fracture surface.

This study investigates the feasibility of collaborative use of recycled carbon fiber reinforced polymer (RCFRP) fibers and recycled aggregate (RA) in concrete, which is called RCFRP fiber reinforced RA concrete (RFRAC). The mechanical properties of the composite were studied through experimental investigation, considering different RCFRP fiber contents (0%, 0.5%, 1.0%, and 1.5% by volume) and different RA replacement rates (0%, 10%, 20%, and 30% by volume). Specifically, ten different mixes were designed to explore the flowability and compressive and flexural strengths of the proposed composite. Experimental results indicated that the addition of RCFRP fibers and RA had a relatively small influence on the compressive strength of concrete (less than 5%). Moreover, the addition of RA slightly decreased the flexural strength of concrete, while the addition of RCFRP fibers could significantly improve the flexural performance. For example, the flexural strength of RA concrete with 1.5% RCFRP fiber addition increased by 32.7%. Considering the good flexural properties of the composite and its potential in reducing waste CFRP and construction solid waste, the proposed RFRAC is promising for use in civil concrete structures with high flexural performance requirements.
