Frequently Asked Questions

Product Information

What are carbon fiber trusses and beams from Element 6 Composites?

Carbon fiber trusses and beams from Element 6 Composites are lightweight, high-strength structural components designed as alternatives to traditional materials like steel, aluminum, and fiberglass. They are engineered for applications requiring minimum weight and maximum stiffness and strength, such as robotics, UAVs, and portable structures.

What construction methods are available for carbon fiber trusses?

Element 6 Composites offers two main construction methods: (1) using square tubes and gussets for high strength and customization, and (2) using patented connectors with pultruded round carbon fiber tubes for extremely low weight and versatile assembly options.

How customizable are Element 6 Composites' carbon fiber trusses and beams?

Trusses and beams can be customized in terms of tube dimensions (from 3/4”x3/4” to 2”x4” and larger), wall thickness, gusset geometry, layup schedules, and material combinations. Customization ensures the structure meets specific strength, stiffness, and weight requirements for each application.

What is the typical weight and load capacity of your carbon fiber trusses?

For example, a carbon fiber truss made from 3/4” x 3/4” tubes and gussets weighs only 6 pounds and withstood a cantilever test load of 800 pounds without breaking. Pultruded carbon fiber trusses have held over 500 pounds in cantilever load tests.

Carbon Fiber Trusses & Beams

Carbon Fiber Tubular Frames

Carbon fiber composites provide an alternative to conventional materials, for example steel, aluminum, and fiberglass, for the construction of lightweight carbon fiber trusses and frame structures.

Element 6 Composites has developed two methods for building carbon fiber tubular frames: one with high strength, robustness, and customization, and the other with extremely low weight.

Square Tubes and Gussets

The first construction method for these types of carbon fiber building structures is using tubes and gussets. The tubes range from as small as 3/4”x3/4” to 2”x4” and even larger. In addition to overall dimensions, wall thicknesses, gusset geometries, and layup schedules can be customized to meet the needs of each application.

For example, uni-direction carbon fiber can be added to individual members to increase bending/axial stiffness and strength. Likewise, gusset thickness and geometry can be adjusted to ensure proper shear stress transfer through the joints. NeiNastran composite FEA calculations are used to optimize structures for minimum weight, while maintaining the specified strength and stiffness requirements.

Weighing in at only 6 pounds, this carbon fiber truss comprised of ¾” x ¾” tubes and gussets, was subjected to a cantilever test load with 800 pounds placed at the end without breaking.

UAV Flight Test Truss

Captive testing of a small UAV was conducting using a 50-foot long wire-braced truss. All of the compression members of the truss were made using carbon fiber square tubes and gussets. The tension members were steel wire. FEA analysis was performed on the entire structure to ensure adequate strength and stiffness.

Pultruded Round Tubes and Connectors Truss

An alternative lightweight, and often cost-effective, carbon fiber construction method is using our patented connectors and pultruded carbon fiber tubes. The connectors give a great deal of versatility to the structural designer, with infinite combinations of lengths and angles, and a wide array of attachment components.

In addition, the skills necessary for construction of this type of structure are relatively easy to master. Element 6 Composites specializes in both design and fabrication; however, many of our customers have the in-house capability to assemble the final carbon fiber building structures once we have worked together through the design and prototyping phases of development.

The picture to the left shows a cantilever load test of a pultruded carbon fiber truss that held over 500 pounds.

Multiple fabrication methods and material combinations are available, each with specific advantages. Using Nastran FEA modeling and proprietary fabrication processes, customized bending and torsional stiffnesses are possible to minimize weight. Often customers have a working assembly constructed from metal that would benefit greatly from reduced weight and increased stiffness; however, do not have the experience internally to redesign the structural members in carbon fiber composites. The engineers at Element 6 Composites are glad to discuss your project and how we can help both in the design/prototyping, as well as low and high-volume production phases of your program.

Cantilever beam testing and corresponding finite element analysis results for a carbon fiber beam. Using a combination of FEA and experimental testing, Element 6 Composites is able to build highly optimized carbon fiber structural beams for each customer and application.

A 24-foot long arched box beam was designed for an application that required a lightweight structure to support a heavy distributed load. Several rounds of analytical and finite element analyses drove optimization. A combination of selective carbon fiber placement and hole pattern provided a minimum weight design that met all strength specifications.

Small box beams used as wing spars for an unmanned airplane. The parts were built up out of off-the-shelf Dragonplate components, providing a cost-effective solution and rapid turn-around time for the customer.

Carbon Fiber Truss Applications

The applications for lightweight carbon fiber trusses and beams are endless. Some examples include robotic support structures and end-effectors, replacements for cantilevered beams in high-speed or portable applications, tradeshow booths, and unmanned vehicle frames. If the application requires minimum weight, yet high stiffness and strength, carbon fiber trusses or beams may be a solution worth investigating.
