Journal of Periodontology, 1979
Temporary splints to immobilize periodontally diseased teeth were made by fiber glass bonded and attached to the teeth with acid-etch technique with BIS-GMA resin. Twenty-one splints were made. Observation time ranged from 4 to 14 months. During the observation only one splint fractured and was repaired while the others functioned without failure.

AbstractMany workers exposed to glass fibers experience an intense pruritus (itching), sometimes accompanied by erythema, erosions, and dermatitis.Patch tests to glass fibers provoked a papulovesicular dermatitis in about 25% of normal persons. Workers in the glass wool industry, whether or not clinically symptomatic, had the same levels of patch‐test ...

Advanced Photonics, 2011
Fluoride glass fibers have been first intensively developed for long haut telecommunication applications due to their ultra low theoretical optical loss (0.001 dB/km). After many years of intensive research, unfortunately, this goal has not been reached yet and remains a challenge.

Abstract This article discusses the types, oxide composition, as well as mechanical and physical properties of general-purpose and special-purpose glass fibers. It describes the glass melting and fiber forming processes and provides information on important commercial products such as continuous roving, woven roving, fiberglass mat ...

Research in Glass and Glass Fibers
Financial Analysts Journal, 1956The Fiber Glass Company research department is naturally much smaller and less diversified in talent than in the Libbey-Owens-Ford Technical Department. Nevertheless, the amount spent on research and development by this relatively young and small company is about 3% of net sales.

Abstract The difference between glass rods and glass fibers is merely a matter of diameter. Anyone who can be trusted with a chemistry set can draw a fiber easily from a glass rod. Hold the two ends of a rod several inches long and put the middle in a hot flame. The heat softens the glass, melting the rigid solid into a thick, viscous
