Manufacturing Technology for Production of High-Strength,High -Modulus,Glass Fibers.

摘要

Amanufacturing process was developed for the multiple-filament production of a glass fiber of high strength and high modulus (800,000psi (800ksi) and 15 x 100,000respectively) suitable for use in reinforcing plastic structures. Preliminary processing and military-type product-quality specifications were prepared. Classical composition experiments were conducted to improve the fiberization characteristics of 970S glass through minor modifications. Physical properties of these glasses were determined (densities,thermal expansion,viscosities,liquidus temperatures,softening points,and refractive indexes),as well as the dielectric constant and loss tangents. A facility constructed for the production of 970S glass was operated to accommodate bushing-design and glass-control studies. (Author)
