Stiffness Comparison 

• Filament-wound composites can be fabricated to match the stiffness of traditional materials

• Stiffness can be customized by varying fiber type and reinforcement angle

The Effect of Wind Angle on Stiffness 

• The structure’s stiffness is controlled by the orientation of the reinforcing fibers

• Custom winding meets the specific requirements of each application

Ultimate Tensile Strength Comparison 

• Superior strength (customized by fiber selection and reinforcement angle)

• Does not yield or plastically deform like metal
