Summary:

The objective of this work is to present the study on experimental data of the strength characteristics of Carbon fiber reinforced thermoset polymer tubes used in manufacturing of Formula SAE racecar suspension. The detailed explanation of a new approach used in fabricating high quality tubes is described. The design objective of reducing weight while maintaining the structural integrity is met. Suspension components on any racecar must maintain a balance between weight, stiffness, strength, cost and manufacturability. Due to the nature of the scoring in the Formula SAE competition, weight, stiffness and strength are normally the three driving factors which make composites the ideal material for many suspension components. Pushrods, A-arms and steering arms are well suited to composites due to the axial tension-compression load path they undergo. Composite materials can be tailored to meet this load path better than any other material due to their anisotropic properties. Also, the high stiffness and strength to weight ratio of carbon fiber produces a part with increased strength and stiffness and decreased weight. Hollow composite structures can be difficult to manufacture as pressure needs to be applied to both in internal and the external side of the laminate. Usually most carbon fiber tubes with a continuous profile are manufactured by either pultrusion or filament winding each method has its own advantage and disadvantage. The manufacturing technique applied in this work is better suited to applications where small length custom lightweight and stable tubing is required. The response of tubes undergoing failure mechanisms during axial and bending loads by destructive testing are discussed and well represented by the finite element model
