“…The enhancement in flexural strength and modulus of GFRE fabricated with integrated techniques are 276.23 MPa and 13.015 GPa, respectively. The increase in the flexural strength and modulus were 4.2% and 18.3%, respectively, [70]. Moreover, woven E-glass/ Epoxy composite laminates was fabricated by VARI technique with a flexural strength of 250 MPa at 40% fiber volume fraction.…”

Vacuum-Assisted Resin Infusion (VARI) and Resin Transfer Molding (RTM) techniques are the most common techniques for the manufacturing of polymeric composite laminates. The VARI technique has a lot of advantages such as low cost, free voids laminates and the ability to produce complex shapes. However, it has some drawbacks such as poor surface finish and temperature instabilities. On the contrary, the RTM technique can withstand high temperature, producing a good surface finish and complex shape laminates. However, it has a high tooling cost and poor quality laminates due to void contents. In this study, a new technique integrated both VARI and RTM techniques is developed to minimize their drawbacks. This technique involves using a semitransparent composite plate instead of a vacuum bag in the VARI technique. This semitransparent plate takes the inverse shape of the composite laminate similar to the RTM tooling. However, this plate has a low cost compared with RTM tooling and allows monitoring of the resin flow during the infusion process. To validate the integrated technique, the mechanical properties of composite laminates are compared with that produced by hand layup technique (HLT). Moreover, the influence of incorporation of 0.25 wt. % and 0.5 wt. % of titanium dioxide (TiO2) nanoparticle into woven and chopped fiber/epoxy composite laminates was demonstrated. The results indicated that the laminates fabricated by the integrated VARI method showed higher mechanical properties than those produced by the hand-layup technique. Moreover, glass fiber/epoxy filled with 0.25 wt. % of TiO2 nanoparticles gives high mechanical properties.

“…However, 3-D woven composite has better shear and bending behavior in comparison to multiaxial warp-knitted composite [4] due to the existence of Z-yarns in thickness of fabric. In comparison to 2D plain weave composite with same fiber volume fraction, the 3-D orthogonal woven composite exhibited improved mechanical properties including tensile strength, flexural strength, impact strength and inter-laminar shear strength (ILSS) [5]. In order to avoid the delamination, the 3-D orthogonal woven fabric is selected to fabricate the blade.…”

As key part in wind turbine, the blade is a vital component for energy transformation. Fiber reinforced composite has advantage of light weight, large specific strength and specific stiffness, which has been used in wind turbine blade. In order to avoid delamination of conventional laminate and debonding between fiber and epoxy, the silane modification composite specimen reinforced with 3-D orthogonal woven fabric/epoxy was prepared using vacuum assisted resin transfer molding (VARTM) for blade. As for fatigue experiment, the critical stress levels corresponding to micro-crack initiation and failure of composite were obtained by combining of acoustic emission technology and quasi-bending experiment. The fatigue behavior of 3-D orthogonal woven composite with silane modification was experimental evaluated based on the minimum and maximum stress levels. The fatigue behavior, such as S-N curve, stress-strain behavior and stiffness degradation behavior were analyzed. The result will provide the basis for investigation of bending behavior with nondestructive tests and set of stress level in bending fatigue experiment.

“…Although the well-designed and well-maintained concrete structure can withstand various loads during many years of operation, due to the role of heavy vehicles and the erosion of the environment, the concrete bridge deck needs frequent maintenance, and still need to be renovated and replaced. For these reasons, 3D (three-dimensional) I-shaped woven composites have been used to overcome these difficulties due to their excellent mechanical properties [1].…”

This paper dealt with the bending properties of 3D (three-dimensional) I-shaped woven composites with basalt fiber filaments tows and epoxy vinyl resin. The 3D I-shaped woven fabrics with three different heights were woven on ordinary loom by reasonable design with low cost. The 3D I-shaped woven composites were fabricated by VARTM(vacuum assisted resin transfer molding) process. The bending tests were conducted on a microcomputer control universal testing machine (TH-8102S). The load-displacement and energy-displacement scatter plots were obtained from experimental tests. The results showed that the polynomial fitting formula were obtained by the calculation of least square method in the software of origin 8.0. Through the analysis of the mathematical equation and correlation coefficient of load-displacement and energy-displacement relationship.it was seen that the fitting effect of the curve was very good.The mathematical equation of this method can be used to simplify the calculation of load, energy from displacement.
