In this paper, an experimental investigation on ultrasonic welding of polyamide composites reinforced with glass fiber has been carried out. The effect of ultrasonic welding parameters, such as welding time, air pressure, hold time and the amount of glass fiber in the composite on tensile strength of weld joints were determined using response surface methodology. This methodology was applied fo...

This work describes the study to investigate and compare the mechanical and thermal properties of raw jute and glass fiber reinforced polyester hybrid composites. To improve the mechanical properties, jute fiber was hybridized with glass fiber. Polyester resin, jute and glass fibers were laminated in three weight ratios(77/23/0, 68/25/7 and 56/21/23) respectively to form composites. The tensile...

We have succeeded to develop a technique enabling molecular level composite treatment by utilizing electrical characteristic (ion) of the materials to form 3D micro-structure, and it can bind three-dimensionally and selectively cross points of continuous (fibriform) object of nanometer size with high-speed and low cost. Application fields of the proposed technique may be fiber process, composit...

A superhydrophilic and underwater superoleophobic surface is fabricated by simply coating silica nanospheres onto a glass fiber membrane through a sol-gel process. Such membrane has a complex framework with micro and nano structures covering and presents a high efficiency (more than 98%) of oil-in-water emulsion separation under harsh environments including strong acidic and concentrated salty ...

The grafted-graphene oxide/glass fiber/epoxy resin (grafted-GO/GF/EP) and dispersed-graphene (dispersed-GO/GF/EP) composites were successfully prepared by grafting graphene oxide (GO) on glass fiber (GF) with coupling agent random dispersion of GO. A scanning electron microscope (SEM) was employed to characterize the micro structure. heat transfer RVE models grafted-GO/GF/EP dispersed-GO/GF/EP ...

The composite materials are normally made of reinforcements and resins. High-performance composites generally termed hybrid materials. Generally, fiber-reinforced laminates very weak in their out-of-plane properties, to address this issue unidirectional (UD) Glass prepared by modifying epoxy matrix using plasma-treated multi-walled carbon nanotubes (MWCNTs) compared with low-cost micro fillers ...

In this work, we report the potential use of novel carbon nanofibers (CNFs), dispersed during fabrication of glass fiber composites to monitor damage propagation under static loading. The use of CNFs enables a transformation of the typically non-conductive glass fiber composites into new fiber composites with appreciable electrical conductivity. The percolation limit of CNFs/epoxy nanocomposite...

To quantify the homogeneity of fiber dispersion in short fiber-reinforced polymer composites, a method for image texture analysis 3-dimensional X-ray micro computed tomography (µCT) images is presented this work. The adaption to specific requirements composite material accomplished using statistical region merging approach. Subsequently, applied evaluating specimens from an intermediate step lo...

The term “glass fiber” as used here refers to any rigid, vitreous fiber, mineral or organic. “Glass” is a physically defined state of matter and not a product with a specific chemical composition. To cause health complaints it must be large enough to be trapped by the upper respiratory system. Crystalline fibers, such as the asbestos minerals and other fibrous minerals and vitreous fibers that ...

The design and fabrication of a tellurite glass multimode optical fiber for magneto-optical applications are presented and discussed. The analysis of the polarization shows that an optical beam, linearly polarized at the fiber input, changes to elliptically polarized with an ellipticity of 1∶4.5 after propagating down the fiber. However, the elliptical distribution remains unchanged with or wit...
