Carbon Curing in the Heat Press

Carbon Curing in the Heat Press

Carbon Curing in the Heat Press Now that we have removed most of the air from the laminate we can move on to curing the part. The envelope bag is removed and the tool is slid into a heat press. The press applies 20 tons of closing force on the tool and air lines are hooked up to the internal bladders. The press platens are heated to 130 degrees Celsius heating the tool. A thermocouple placed in the tool monitors the temperature of the part. The resin properties are rapidly changing as it h...

Carbon Mold Debulking

Carbon Mold Debulking

Carbon Mold Debulking Leaving layup, the result is a loaded closed tool that could go straight to curing.  The only issue with that is through the layup process we have unwittingly trapped a bunch of air in the layup.  Laying down sheets of carbon is not unlike laying down stickers, add to that a lot of complex curves and it is easy to visualize a bunch of small air pockets getting trapped.  If that air remains in place, it can cause voids, surface defects, and a host of both structural an...

Carbon Cutting & Kitting

Carbon Cutting & Kitting

Carbon Cutting & Kitting Carbon Cutting & Kitting begins the manufacturing process. After months of FEA, prototyping testing, and riding, the result is a recipe of over 300 unique carbon plies that will give the performance and strength desired in our bikes. These ply shapes are nested into cutting patterns and sent to our cutting team who cuts and organize the kits by part. The Mitsubishi fibers, pre-pregged in Irvine, California, provide the right balance of strength and stiffnes...

How an Arkansas Upstart Is Making America’s Best Carbon Fiber Bikes

How an Arkansas Upstart Is Making America’s Best Carbon Fiber Bikes

by Aaron Gulley  In a windowless office park in Little Rock, AR, Tony Karklins holds up a sheaf of black carbon-fiber fabric cut into various trapezoids and rectangles the length of his forearm. “This is your top tube,” he says. “Every carbon bike starts like this.” With ruddy cheeks and a flop of sandy brown hair, Karklins is the founder of the upstart bike brand Allied Cycle Works. I’ve come to Arkansas to pick up a test bike. But first, Karklins wants me to help build it. Under th...

Outside Magazine: Your Next Carbon Bike Will Be Made in Arkansas

ALLIED CYCLE WORKS, based in Little Rock, is trying to ignite American carbon-fiber manufacturing and steal China’s thunder by Aaron Gulleyphoto by Brian Clifton If you ride a carbon-fiber bike, chances are it was manufactured in one of five factories in China. If you ride an American-made carbon model, you probably bought it from a boutique brand and paid through the teeth for it. All this might change thanks to Allied Cycles, which launched in February in Little Rock, Arkansas. Allied want...
