Woven fiberglass cloth offers the widest range and the best control over thickness, weight and strength of all forms of fiberglass textiles. This offers the materials engineer a wide choice of controlled fabric properties to satisfy design needs and objectives. In general, woven fiberglass cloth has the following properties:
High Tensile Strength: Fiberglass cloth is one of the strongest textile fibers, having greater specific tensile strength than steel wire of the same diameter, at a lower weight. Dimensional Stability: Fiberglass cloth has low elongation under load, generally 3% or less. Glass fibers produce fabrics with excellent dimensional stability under various types of conditions. High Heat Resistance: Fiberglass cloth has excellent heat resistance at relatively low cost. Fiberglass cloth retains approximately 50% of room temperature tensile strength at 700°F (371°C); approximately 25% at 900°F (482°C); with a softening point of 1555°F (846°C) and a melting point of 2075° F (1121 °C). Fire Resistance: Fiberglass cloth is composed of inorganic materials, and are noncombustible, a natural choice where flammability is of concern. Good Thermal Conductivity: The rapid heat dissipation of fiberglass cloth is particularly important in electrical insulation applications. Good Chemical Resistance: Like glass itself, fiberglass cloth is highly resistant to attack by most chemicals. Outstanding Electrical Properties: Fiberglass fabric withstands high temperature and has low moisture regain. Along with its high dielectric strength and low dielectric constant, glass is of major importance and usefulness in the electronics. Durability: Being inert, fiberglass cloth is unaffected by sunlight, fungus or bacteria. Economical: Fiberglass cloth is lower in cost than many other fabrics for similar applications.
