Affordable Aerospace Materials Come to Quarter Midget Racing

BAC’s Carbon Fiber/Aluminum Quarter Midget Axles are approximately ½ the cost of titanium axles, but 16% stronger, and are cost competitive with aluminum axles, but 51% stronger. This results in an axle of greater value. The increase in strength results in 1) greater durability on the track (wheel banging) 2) less maintenance (don’t have to replace bent axles every time wheel or wall contact is made.)  

U.S. Patent-Pending Design

The BAC Carbon Fiber/Aluminum Axle design utilizes the highest strength carbon fiber material which is fabricated via a filament winding machine (not hand-rolled carbon fabric).  This results in the highest strength/lightest weight axle possible.  The BAC Carbon Fiber/Aluminum is a homogeneous shaft that has no keyway cuts or snap ring grooves cut into the carbon fiber.  Keyways are provided in an integral aircraft aluminum alloy sleeve which is pressed and bonded (fused) over the entire outside diameter of the carbon fiber shaft.  This patent-pending sleeve design encapsulates the O.D. of the carbon fiber shaft in all the critical areas.  Therefore, even if an impact load exceeded the ultimate bending strength of the axle assembly, the carbon fiber would never fracture, splinter, or break off.
