Carbon or Fiberglass? How to Choose

Monday, July 16th, 2012

So you want to use a modern composite in your structure.  How do you choose between carbon and fiberglass?

There are many factors that come into play, but the big ones are price, weight, conduction, and signal interference.

Let’s start with price: fiberglass is much less expensive than carbon.  For instance, one solid 1/4-inch diameter round carbon rod at 48″ long will cost you $12.49 at www.goodwinds.com.  But a solid 1/4-inch diameter round fiberglass rod at 48″ long will cost a mere $1.69.

However, fiberglass is much heavier than carbon.  That same 1/4-inch diameter carbon rod weighs 60.3 grams (2.13 oz) while the fiberglass rod weighs 78.5 grams (2.8 oz).  That can be a significant difference when you’re building some that is meant to fly, or that the rest of the structure will have to support.

Carbon is mildly conductive, but fiberglass is not conductive at all.  Furthermore, if you’re building an antenna, fiberglass is radiolucent, meaning that it allows radiation to pass through it freely.  No signal interference from fiberglass (carbon will interfere with your signal) makes it an ideal composite for your antenna.

Hammocks and Other Interesting Ways to Use Composite Rods and Tubes

Thursday, June 9th, 2011

In addition to all of the really cool industrial customers with whom we work (Boeing, Blimpworks, NASA, and so many more), we supply composite carbon and fiberglass rods and tubes to a variety of small businesses and manufactures making some really interesting stuff.  Did you know that you can use Goodwinds carbon and fiberglass as framework for your backpacking hammock?  Check out hammockforums.net for more inspiration.  There are lots of ways to use composites in RC cars, helicopters, and airplanes (especially foamies!).  You can find some really neat RC projects at rcgroups.com and rcuniverse.com.  Some of our customers are also active with LARP, archery, spear fishing, hiking (using composites for hiking sticks), puppet making, and other great hobbies.  How do you use carbon and fiberglass?

Carbon Prices on the Rise

Monday, May 9th, 2011

One of the great advantages to buying carbon rods and tubes from Goodwinds is the absence of minimum orders.  We have fantastic prices for low quantities, and quantity discounts when you order more.  The reason we are able to do this is that we purchase large quantities of rods and tubes at long lengths and then cut them to spec for our customers.  Recently, our carbon manufacturer has raised the prices of carbon rods and tubes – twice within the past 6 months!  The reason for this is a global increase in the price of carbon fibers.

It is possible to still purchase inexpensive Chinese carbon rods and tubes.  Chinese carbon is made with fewer carbon fibers and more vinylester or epoxy (the glue that binds the carbon fibers together) than American carbon, and is less strong as a consequence.

Because Goodwinds supplies many industrial companies with carbon, we have chosen to continue to supply high-quality, American-made carbon rods and tubes to our customers.  We understand that quality is important to our customers, whether you are a hobbyist or one of our industrial partners or an engineer.  You will see prices rise at Goodwinds, but hopefully not very much as we work with these new price fluctuations.  And we will always offer quantity and wholesale discounts.  Please contact us with any questions.
