Composite Motor Development

The CU Boulder Sounding Rocket Laboratory’s Composite Motor Development team brings together our expertise in solid rocket propulsion and composite manufacturing to create custom solid rocket motors at an unprecedented scale for a student team. We’ve accumulated a wealth of knowledge over the past three years of the program, and have static fired upwards of two dozen composite motors, ranging in diameter from 1 inch to 8 inches.

What We Do

The composite motor team is responsible for designing, manufacturing, and testing the propulsion systems that power all of SRL’s solid-fueled motors. Our long-term goal is to create low-cost and lightweight carbon fiber motors to enable frequent research flights from the CU community. We work with new materials such as carbon fiber, kevlar, ceramics, and more to develop casing and nozzle designs as we improve motor technology. Composite motor rapidly designs, builds, tests motors to scale up to the R class booster powering Spaceshot.
