BYU Students Win Cali Bamboo Contest with New Composite Material
– Three mechanical engineering students create extra-strong bridge beam using bamboo fiber –
SAN DIEGO –March 3, 2012 Cali Bamboo, a premier manufacturer of green building materials, has awarded its February Project of the Month prize to Alex Stiles, a mechanical engineering student at Brigham Young University, for the composite material beam he created using bamboo fibers.
Stiles, along with fellow engineering students Steve Gardner and Roger Smith, used fibers extracted from Cali Bamboo’s bamboo matting as the raw material for a natural fiber double I-Beam. The BYU students used the beam to construct a bridge for the 14th Annual SAMPE (Society for the Advancement of Material and Process Engineering) Student Bridge Contest in Long Beach, California. Their bamboo bridge competed against ten other university teams and took home second place in the competition’s natural fiber category.
The team’s overall goal is to develop a low-cost fiber separation technique that enables less developed nations to produce bamboo fibers strong enough to serve as a natural alternative to fiberglass. According to Stiles, “bamboo is cost-effective and renewable, and bamboo strips offer the right composition to undergo chemical treatments.”
Watch a video produced by BYU Weekly about the team’s bamboo fiber research.
Speaking of his project on the BYU Mechanical Engineering news webpage, Stiles says, “The success of BYU’s bamboo bridge supports the goal of my ORCA research, which is focused on improving the method for manufacturing bamboo fibers strong enough to serve as a viable fiberglass alternative.”
“The bamboo matting was donated by Cali Bamboo. But it was thanks to the team’s devotion and hard work that we were able to take a fledgling research project and produce a very successful bamboo fiber bridge. I hope that BYU’s success at the competition this year will help inspire engineering students to get involved with composites and help BYU take home first place next year!”
Stiles’ natural fiber double I-beam received the most votes in Cali Bamboo’s February Project of the Month Contest, and he will be receiving a $500 Cali Bamboo gift certificate. He plans on spending his winnings on more bamboo building product for continued research.

Oh okay, I can imagine it would take a lot of time. Thanks for the reaction.
What is the exact cost to make a double I beam of dimension of 3*2*2 feet
Hello,
While we don’t offer this product, I do remember that it was a fairly painstaking process as they were pulling apart individual strands of bamboo from a matting material we used to offer and laying them in a matrix pattern and adding polyester resin.
Send me more information on the bamboo beams , I want to build bridges.
Hi Ernest,
Are you referring to bamboo lumber? We discontinued it about 5 years ago. While it certainly was an interesting product with lots of useful potential, we ultimately decided not to pursue further development. We do however still carry bamboo plywood, it’s great for furniture but probably not bridges.
Hi Walker,
What was the reason to not pursue further development?
Hi Stan,
Not certain, but I do recall them mentioning the technique that performed best was made with very thin bamboo fibers individually pulled from the raw bamboo matting, and it was a very time-consuming process.
