Medium Diameter Structural Carbon Tubes 3.0", 3.9", and 6.0"
Originally developed for use as airframes on small research rockets, we are now offering these tubes for all other applications. Our carbon fiber tubes are convolute wrapped ("roll wrapped", similar to the way G-10 tubes are made) using actual aerospace quality carbon fiber cloth. The cloth we use is a very tight 3k 8 harness satin weave common in aerospace applications. Fiber orientation is 0/90 degrees and has a fiber/resin ratio of 60/40% by weight (40% resin content). The laminate is cured under pressure and at temperatures of over 250 degrees F. Once cured, the tubes are fine sanded and nearly ready for paint. Appropriate primers and prep will be required.
The shipping costs listed below are for the contiguous 48 states via Ground UPS. Please inquire for shipping to AK, HI and all international destinations firstname.lastname@example.org . Shipping to Canada via USPS is generally just a few dollars more than shipping within the states. Shipping costs to Europe typically run high depending on the tube ordered and the destination country. International destinations vary widely and some have strict package size limits.
Shipping for multiple items will always be combined manually for the best rate. Your card may be charged a lesser amount or your PayPal account will receive a refund to reflect the lower shipping rate.
