A little late to this thread but I remember being at the Outdoorsmans store a few years back and my engineering head almost exploded when they told me they used aluminum instead of carbon because it was more rigid and had less vibration. I have no question the way they utilize the materials the end effect is better but it’s not that cut and dry either.
If you take two dimensionally indentical tubes of aluminum and carbon fiber hang them from a string and then hit them the carbon fiber will damp quickly and the aluminum will ring like crazy for an extended period. Similarly if you have ever ridden a carbon fiber road bike frame and a really stiff hydroformed aluminum frame the vibration on the aluminum frame will be a lot lot worse.
The reason Outdoorsmans uses aluminum is that economically viable for them to do small batches of production. The economics to make 1,000 pieces and 1,000,000 pieces will drive wildly different prices with different production processes. Aluminum works for these relatively niche product volumes and US manufacturing.
With regard to carbon fiber manufacturing for consumer products, there is almost no domestic manufacturing capability in the US. It’s a process that has really come into its own in the last 2 decades after most manufacturing had been heavily offshored. Southeast Asian has the vast majority of carbon fiber manufacturing capacity and knowledge when it comes to consumer goods. The US certainly has capabilities for aerospace and defense composites, but they aren’t the ones making $250 tripods. Carbon fiber manufacturing isn’t really a choice between cheap offshore labor and American manufacturing, rather there isn’t much choice to for domestic CF manufacturing without tooling up to do it all yourself. So far as I can tell Outdoorsmans is contracting out their aluminum manufacturing to local machine shops and probably doesn’t have the business case to create a carbon fiber shop from the ground up.
With these relatively inexpensive carbon fiber tripods, you are getting tubing made with relatively simple manufacturing methods and uniform carbon layups. There is a huge difference between pulltruded composites and mass rolled tubing than custom molded composites using variable layups in Aluminum molds with really high quality prepreg, vacuum bagging and autoclaves. Fundamentally, aluminum is Uniform in it material properties whereas carbon fiber is all about the orientation of the weaves. If you are NOT Designing the carbon layup for each part and it’s specific loading you won’t get benefit from carbon fiber over quality aluminum. Carbon fiber is also horrible in compression loading and excellent in tension. This is a fundamental problem when your product requires clamping tubes together.
There are a lot of misconceptions around carbon fiber and manufacturing that this will hopefully explain. I really like the Outdoorsmans gear and believe the AZ guys to know glassing better than anyone based on my experiences there. It just happens they are using the academically lesser material with intimate knowledge of hunters glassing demands to make the better product.
