Biaxial sleeve is braided, rather than woven, and features cosmetics much like that on our fabrics featuring the 2x2 twill weave pattern. They have been designed to be biaxial, meaning that they have properties that allow them to be strong and stiff in two directions.

These sleeves are typically used to reinforce or strengthen other materials, and are often used in the construction of aircraft, auto, and other high-performance structures where lightweight and high strength are important. They can also be used to repair damaged or weakened parts, or to improve the performance of existing structures by adding additional strength and stiffness.

Sleeves can be slid over a prepared mandrel or cylinder to create straight or tapered tubing. Sleeves completely conform to the shape of products with changing geometries, like prosthetics and hockey sticks.

Overall, braided biaxial sleeves improve performance, minimize weight, and maximize strength properties for a variety of unique applications.

Laying up sleeve is predictable, repeatable, and suitable for precise manufacture of composite parts. Braided sleeve is extremely resistant to cracks between layers, reducing the possibility of delaminating and increasing the strength of the product.

A sleeve can be increased from its base diameter up to 30% and decreased up to 70%. This means our 2" sleeve can be used in a single application, from 0.6" to 2.6" in diameter.

When inflated, braided reinforcement works much like a shark's body, orienting itself to the direction of force. This strengthens its outer skin, enabling it to withstand pressure, carry load, and tolerate damage and fatigue. If a puncture does occur, the sleeve provides a slow, controlled failure, rather than a more damaging and potentially dangerous blowup.

Braided fiberglass, carbon fiber, and Kevlar sleeves are specialized forms of protective sleeves or sheaths made from varied materials. Here is an overview of each type:

Braided Fiberglass Sleeves: Braided fiberglass sleeves are made from high-temperature-resistant fiberglass yarns that are braided together to form a protective sleeve. They provide excellent thermal insulation and can withstand high temperatures. These sleeves are commonly used in automotive, aerospace, and industrial applications to protect wires, hoses, and cables from heat, abrasion, and chemicals.

Carbon Fiber Sleeves: Carbon fiber sleeves are composed of carbon fiber yarns that are woven or braided to create a sleeve-like structure. Carbon fiber offers a high strength-to-weight ratio and excellent stiffness properties. Carbon fiber sleeves are often used in aerospace, automotive, and sporting goods industries to provide reinforcement and protection to cables, tubes, and other structural elements.

Kevlar Sleeves: Kevlar sleeves are known for their high strength and heat resistance. Kevlar sleeves offer exceptional cut and abrasion resistance. They are commonly used in industries like aerospace, defense, and manufacturing to protect cables, hoses, and wires from extreme temperatures, chemicals, and mechanical stresses.

All three types of sleeves provide numerous benefits, including protection against heat, abrasion, and chemicals. They are flexible, lightweight, and can be easily installed or removed. The specific choice of sleeve material depends on the application requirements, such as the level of protection needed and environmental conditions.

Fibre Glast is committed to ensuring that every roll of braided sleeve 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. All our products are certified and traceable.
