THE EFFECT OF E-GLASS FIBERS AND PHLOGOPITE MICA ON THE MECHANICAL PROPERTIES AND DIMENSIONAL STABILITY OF RIGID PVC FOAMS by Murtatha M. Jamel The University of Wisconsin-Milwaukee, 2015 Under the Supervision of Professor Nidal Abu-Zahra Short E-Glass Fibers (GF) and Phlogopite Mica (M) were used separately and simultaneously to enhance the dimensional stability and mechanical properties of ex...

In this paper we present significant progress on the fabrication of small-core lead-silicate holey fibers. The glass used in this work is SF57, a commercially available, highly nonlinear Schott glass. We report the fabrication of small core SF57 fibers with a loss as low as 2.6 dB/m at 1550 nm, and the fabrication of fibers with a nonlinear coefficient as high as 640 W-1km-1. We demonstrate the...

1. Abstract Natural fibers are being increasingly used to substitute artificial glass and carbon fibers in polymer composites. It is important to know how the mechanical properties of these natural fiber composites compare with those of the traditional glass and carbon fiber composites. Glass and carbon fiber composites are currently being used in many applications that may not require such hig...

Herein we describe a method to fabricate submicron bioactive glass tubes using sol-gel and coaxial electrospinning techniques for applications in bone tissue engineering. Heavy mineral oil and gel solution were delivered by two independent syringe pumps during the coaxial electrospinning process. Subsequently, submicron bioactive glass tubes were obtained by removal of poly(vinyl pyrrolidone) a...

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 ...

Composite materials can be defined as a combination of two or more materials that results in better properties than those of the individual components used alone. These materials have high strength and stiffness combined with low density compared to the conventional metals. Polymers are structurally more complex than metals. Polymer – matrix composites are viscoelastic materials and their mecha...

The filters in Eclipse, a new cigarette-like smoking article marketed by R. J. Reynolds Tobacco Company, are contaminated with glass fibers, fragments, and particles. Reported herein are the results of a study in which consumers were questioned about their opinions as to whether exposure to glass fibers in such a filter poses an added health risk beyond that from smoking and whether the manufac...

There is abundant epidemiologic evidence that asbestos fibers can cause lung fibrosis (asbestosis), bronchial cancer, and mesothelioma in humans, as well as limited evidence for such effects in workers exposed to slag and rockwool fibers. Epidemiological evidence for human disease from inhalation exposures to conventional fibrous glass is negative. While health concerns based on the morphologic...

A typical optical fiber is usually constructed of a silicon (glass) material, however, plastic and quartz are also available but normally for data transmission. Today most of all optical fibers manufactured consist of a lightconducting glass core surrounded by a thin layer of glass cladding with a lower refractive index. This cladding serves to protect the core finish. All fibers used in infrar...
