摘要:
A method of forming high strength glass fibers in a refractory lined glass melter is disclosed. The refractory lined melter is suited to the batch compositions disclosed for the formation high modulus, and high-strength glass fibers. The glass composition for use in the method of the present invention is up to about 70.5 Weight % SiO2, 24.5 weight % Al2O3, 22 weight % alkaline earth oxides and may include small amounts of alkali metal oxides and ZrO2. Oxide based refractories included alumina, chromic oxide, silica, alumina-silica, zircon, zirconia-alumina-silica and combinations thereof. By using oxide based refractory lined furnaces the cost of production of glass fibers is substantially reduced in comparison with the cost of fibers using a platinum lined melting furnace. Fibers formed by the present invention are also disclosed.

摘要:
Glass batch compositions for the formation of high-modulus, and high-strength glass fibers as well as fibers suitable for use as textile and reinforcements are disclosed. Fibers formed of the composition are especially suitable for use in high-strength, low-weight applications such as windmill blades and high strength and modulus applications where strength and stiffness are required in the composite. The glass composition is up to about 70.5 weight % SiO2, about 24.5 weight % Al2O3, about 22 weight % alkaline earth oxides and may include small amounts of alkali metal oxides and ZrO2. Fiberglass-reinforced composite articles such as windmill blades are also disclosed.

摘要:
A method and apparatus for collecting texturized strand are disclosed. The apparatus for collecting texturized strand includes a texturizer for expanding a continuous strand of glass fibers into a wool-like product, a container for collecting the texturized strand, and a device establishing a pressure differential between an interior region of the container and a region external of the container. The texturizer includes a nozzle to which a supply of compressed air and a continuous strand are fed. The compressed air advances the strand of glass fibers through the nozzle and expands the strand so that the filaments are spread apart, thereby giving the strand a wool-type appearance. The pressure differential creating device includes a vacuum apparatus for drawing air and a screen through which the air flows. A container is placed on the screen. In the preferred embodiment, the container is a corrugated box that has upper and lower closures or flaps. The lower flaps are folded back, thereby revealing an opening in the bottom. The container is coupled to the pressure differential creating device so that the container opening is in communication with the screen. The nozzle is manipulated to direct the strand from the outlet of the nozzle into the container. The system may include a deflector assembly for changing the direction of the texturized strand as it is directed into the container.
摘要:
A recyclable tufted carpet meeting EPA recyclable content standards and having improved dimensional stability that reduces skew, bow, and wrinkles during manufacture and installation is formed by combining prior art primary and secondary backings into a single, fiber-reinforced primary backing layer. Consolidating either a glass fiber fabric layer, a glass veil, or a glass mat with a fiber-reinforced extruded film forms the fiber-reinforced primary backing layer. An additional glass fabric fiber layer can also be introduced to the primary backing to provide additional dimensional stability.

Glass fibers formed from the inventive composition may be used in applications that require high stiffness and have elastic modulus between 88 and 115 GPa. Such applications include woven fabrics for use in forming wind turbine blades and aerospace structures.
