Fiberglass is the foundation of the composites industry. It is often the best all-purpose choice among reinforcements for creating composite parts with excellent strength, low weight, and dimensional stability.

Fabricators also choose fiberglass because:

  • It provides a quick and affordable way to build parts and molds, and make repairs.
  • It's easy to handle—and you can depend on consistent handling characteristics time after time.
  • It conforms to complex shapes, and withstands tough environmental conditions.

Fiberglass is a versatile and commonly used material composed of fine glass fibers. It's made by extruding molten glass through superfine openings to create threads, which are then woven together to form a flexible fabric. This fabric can be molded into various shapes and combined with resin to create a composite material with high strength and durability.

Here are some key points about fiberglass:

  1. Strength and Durability: Fiberglass is known for its excellent strength-to-weight ratio, making it strong and relatively lightweight. It's resistant to corrosion, chemicals, and is non-conductive, making it a popular choice in various applications.
  2. Versatility: Fiberglass is used in a wide range of applications including the construction of boats, aircraft, sports equipment, as well as a myriad of other applications.
  3. Moldability: Fiberglass' flexibility allows it to be molded into complex shapes and structures, making it a preferred material for manufacturing components that require specific designs or custom shapes.
  4. Composite Material: Fiberglass when combined with resin, typically epoxy, polyester, or vinyl ester, forms a composite material that can be molded into almost any shape. This combination enhances its strength and durability.
  5. Maintenance: Fiberglass is relatively low maintenance, requiring occasional cleaning and, in some cases, reapplication of protective coatings to maintain its appearance and structural integrity.
  6. Cost-Effectiveness: Fiberglass is generally more affordable compared to certain metals and other composite materials, making it an economical choice in various industries.

All of our fiberglass reinforcements are made to be used with resin to create hard, composite parts. Check out our complete selection:

  • Woven Fiberglass Fabric - Glass fibers are bundled into yarns, then woven into a number of different patterns, each with its own weight and unique strength characteristics.
  • Fiberglass Mat - A popular choice for building quick thickness into parts and molds, mat consists of randomly oriented glass filaments held together with binder.
  • Stitched Fiberglass - This fabric style features yarns that are stitched, not woven, to avoid crimping and promote strength properties.

Fibre Glast is committed to ensuring that every roll of fiberglass fabric we handle is First Quality and manufactured to the highest standards. That means you can expect the same properties and handling characteristics every time you order.
