Tube - Fiberglass - 0.25 x 0.32 x 60 Inch
Unlike metals which have similar properties in all directions (isotropic), the properties of composites are varying, dependent on the orientation of the fibers in each layer. This tube is constructed utilizing unidirectional and woven fabric plies. This makes for a true workhorse of a tube with no frills. This tube is great for bending and compression applications.
Features & Benefits
Roll wrapped tubing is manufactured using multiple layers of prepreg carbon fiber (and if noted, other) materials. In general each layer is about 0.006 inches thick which means that a tube with a wall thickness of 0.060 inches will typically be composed of 9-10 individual layers of carbon fiber. The number of layers (plys) allows us to vary the orientation of the fibers throughout the thickness, creating a high performance, engineered product.
*Please note, the diagram below shows an outer "0/90" ply however the product you are currently viewing does NOT have this outer twill ply.

- 0° fibers maximize bending stiffness and run along the length of the part. Consider bending a tube over your knee.
- 45° fibers maximize torsional stiffness and are typically plied together in an opposing manner, i.e. ±45°. Consider twisting a tube like a vehicle's driveshaft.
- 90° (or "hoop") fibers maximize crushing stiffness and generally assist in overall durability. Consider laying a tube on the ground and stepping on it.
