Stiffness Comparison
Stiffness of Custom Fabricated Tubing can be Fabricated to the following:
- Filament wound composites can be fabricated to match the stiffness of traditional materials
- Filament wound composites offer the advantage of customizing stiffness by varying both the type of fiber and the angle of the reinforcement

Effect of Wind Angle on Stiffness
- The stiffness of a composite structure is controlled by the orientation of the reinforcing fibers
- The design engineer must understand the requirements of the application to properly design the filament wound structure

Ultimate Tensile Strength Comparison
- Filament wound composites exhibit superior strength
- They do not yield or plastically deform the way that metal does
- Filament wound composites offer the advantage of customizing strength by varying both the type of fiber and the angle of the reinforcement

The Effect of Wind Angle on Strength
- As with stiffness, the strength of a composite structure is also controlled by the orientation of the reinforcing fibers
- The design engineer must understand the requirements of the application to properly design the filament wound structure
