Detailed Product Description:
This tube is fabricated using “roll-wrap” construction around a precision
machined mandrel. The layup schedule uses standard modulus uni-directional
carbon fiber pre-impregnated with a thermoset epoxy. The use of pre-impregnated
carbon fiber instead of dry fabric maximizes stiffness to weight ratio. This tubing
has a resin/fiber ratio of about 0.49 for optimum mechanical properties.
Additionally, to preserve the esthetics of the classic carbon fiber weave seen
in the photo, an outer layer of bi-directional carbon fiber is included in the layup schedule.

These tubes are made from standard modulus carbon fiber and epoxy resin,
and may be used in applications with service temperatures up to a maximum
of 160°F, with only a slight reduction in strength and stiffness.
Any portion of the tubing to be exposed to UV rays for long periods of time
should be coated with any one of the quality polyurethane paints. To retain
the carbon fiber appearance use any of the automotive clear coats that contain
