These braided carbon biaxial sleeves have the cosmetically desirable appearance of a 2x2 Twill pattern but as a sleeve, they can be slid over a prepared mandrel or tube to create straight or tapered tubing. The sleeves can be increased from their base diameter up to 30% and decreased up to 70%. This means that a 2" diameter can be used in a single application ranging from 2.6" diameter down to 0.6". Laying up sleeves is predictable, repeatable and suitable for precise manufacture of composite parts. Braided sleeves are extremely resistant to cracks between layers, reducing the possibility of delaminating and increasing the strength of the product. When inflated, braided reinforcement works much like a shark's body, orienting itself to the direction of force. This actually strengthens its outer skin, enabling it to withstand pressure and carry load, and to 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 sleeves will also completely conform to the shape of products with changing geometries like prosthetics and hockey sticks, improving overall performance, minimizing weight, and maximizing strength.
