A relatively low-temperature carbon nanotube (CNT) synthesis technique, graphitic structure by design (GSD), was utilized to grow CNTs over glass fibers. Composite laminates based on the hybrid CNTs–glass fibers were fabricated and examined for their electromagnetic interfering (EMI) shielding effectiveness (SE), in-plane and out-of-plane electrical conductivities and mechanical properties. Despite degrading the strength and strain-to-failure, improvements in the elastic modulus, electrical conductivities, and EMI SE of the glass fiber reinforced polymer (GFRP) composites were observed.

Fiber-reinforced polymer-based composites may experience various strain rates under different dynamic loads. As the mechanical behavior of these composites varies with strain rate, their response will be dependent on the strain rate. This paper presents a comprehensive review on glass fibers and composites reinforced with these fibers, as the most practical polymer-based composite, under dynamic loading. First, the properties of long glass fibers under different strain rates will be reviewed in detail. In the following, experimental studies on the effects of strain rate on various types of glass fiber-reinforced polymer-based composites will be categorized and presented. The behavior of thermoset polymers will be also addressed under different strain rates. Finally, various analytical and numerical macromechanical and micromechanical models will be comprehensively described for this type of composites.

Polymer composite reinforced with fiber materials have always proven its superior significant enactment over numerous traditional materials, considering their incomparable strength to weight ratio and stiffness. Carbon nanotubes usage in glass-fiber reinforced polymer has high potential in changing the characteristics of composite laminates. Carbon nanotubes have engrossed composite fraternity in exploring the opportunity of utilizing them as a supplementary reinforcement in fiber reinforced polymer composites. This study examines the mechanical characters of glass-fiber reinforced polymer with and without multi-walled carbon nanotubes (MWCNT). Composite laminated layers are fabricated using epoxy resin without carbon nanotube and with 0.5 and 1.5 % MWCNT. The materials were tested to determine tensile, flexural and compression properties. It is observed that the carbon nanotubes can enhance the mechanical properties in the composite laminates. Composite laminate with 1.5 wt % MWCNT exhibited good mechanical properties compared to that with 0.5 wt % MWCNT and without MWCNT.

There are numerous engineering applications where Glass Fiber Reinforced Polymer (GFRP) composite tubes are utilized, such as desalination plants, power transmission systems, and paper mill, as well as marine, industries. Some type of machining is required for those various applications either for joining or fitting procedures. Machining of GFRP has certain difficulties that may damage the tube itself because of fiber delamination and pull out, as well as matrix deboning. Additionally, short machining tool life may be encountered while the formation of powder like chips maybe relatively hazardous. The present paper investigates the effect of process parameters for surface roughness of glass fiber-reinforced polymer composite pipes manufactured using the filament winding process. Experiments were conducted based on the high-speed turning Computer Numerical Control (CNC) machine using Poly-Crystalline Diamond (PCD) tool. The process parameters considered were cutting speed, feed, and depth of cut. Mathematical models for the surface roughness were developed based on the experimental results, and Analysis of Variance (ANOVA) has been performed with a confidence level of 95% for validation of the models.

This paper presents an investigation into the flexural behaviour of reinforced concrete beam with opening reinforced with two different materials i.e., steel and Glass Fiber Reinforced Polymer (GFRP). Comparison study between the two different materials were carried out and presented in this study through non-linear Finite Element Method (FEM) using the commercial ABAQUS 6.10 software package. The performance of the opening beam reinforced with GFRP is influenced by several key parameters. Simulation analyses were carried out to determine the behavior of beam with opening subjected to monotonic loading. The main parameters considered in this study are size of opening and reinforcement diameter. The results show that GFRP give 23%-29% more ductility than steel reinforcement. The result also shows when the size of opening change from 200mm to 150mm or from 150mm to 100mm the ultimate load capacity increase by 15%. In general, good agreement between the Finite Element (FE) simulation and the available experimental result has been obtained.
