ACP’s Carbon Fiber Twill Roll Wrapped Tubes are manufactured by wrapping carbon fiber unidirectional prepreg tape onto a mandrel in multiple layers and orientations and cured at high temperatures and pressure.
The unidirectional layers are oriented in a 0/90 degree orientation with the majority of the fibers positioned in the longitudinal access. Fibers oriented at 90 degrees (hoop) are wrapped around the circumference to provide high crushing strength and stiffness. The fibers that run along the length, in the 0 degree direction, provide high bending strength and stiffness. This type of construction offers a high stiffness to weight ratio tube with increased bending stiffness and axial strength, a high crush resistance and tight inner diameter (ID) tolerances.
Carbon Fiber Twill Roll Wrapped Tubes have an outermost layer of 2x2 twill fabric which gives the tube a few advantages including better machinability, reduced splintering and the decorative aesthetics associated with carbon fiber. All of our roll wrapped tubes feature a slight rib texture spiraling along their length where shrink-tape has been used in the manufacturing process. If need be, this can easily be sanded and polished away.
