Composites
The composites subsystem of Georgia Tech Motorsports is a specialized division within the Georgia Institute of Technology's Motorsports team that is primarily responsible for the design, development, and fabrication of components and structures using advanced materials, with a particular focus on carbon fiber. This subsystem operates at the intersection of motorsports engineering and cutting-edge materials science, blending practical applications with scientific precision.
What We Do
The role of the composites subsystem extends beyond mere construction. It engages in scientific manufacturing processes, which entails a rigorous and research-based approach to material selection, fabrication techniques, and quality control. Scientific manufacturing emphasizes understanding the fundamental properties and behaviors of materials, enabling engineers to optimize their performance within the context of FSAE.
Key responsibilities of the composites subsystem may include:
Material Selection: This team carefully selects the appropriate grades and weaves of carbon fiber and other composite materials based on the specific requirements of the components they are building. They consider factors such as weight, strength, and rigidity.
Structural Design: Engineers and designers within the subsystem create detailed plans and computer-aided design (CAD) models for the components they are developing. These designs must adhere to strict safety and performance standards.
Manufacturing Processes: The composites subsystem employs advanced manufacturing techniques, such as autoclaving, resin infusion, and precision layup, to produce carbon fiber components with exceptional precision and consistency. They closely monitor and control variables like temperature, pressure, and curing times.
Quality Control: Quality control procedures are integral to the scientific manufacturing process. The subsystem utilizes non-destructive testing methods, such as ultrasound or X-ray scanning, to ensure the components meet their stringent standards.
Research and Development: The composites subsystem may also engage in research to improve existing materials and manufacturing techniques. This research contributes to advancements not only in motorsports but also in other industries that use carbon composites.
History
In the past, the Composites subsystem was a sector of the Aerodynamics subsystem. However, because the demand for carbon fiber manufactured parts has expanded far beyond the Aerodynamics subsystem, a specialized Composites subsystem was developed.
Technical Information
The Composites Subsystem of Georgia Tech Motorsports is at the forefront of carbon fiber technology. Carbon fiber, composed of carbon atoms bonded together in a crystal alignment, is renowned for its remarkable mechanical properties. The manufacturing process involves weaving or layering carbon fibers and reinforcing them with epoxy resin, followed by curing under controlled temperatures and pressures. This results in exceptionally strong and lightweight components that are ideal for use in motorsports.
Future Goals and Projects
Future goals for the Composites subsystem are to integrate a carbon fiber monocoque structure to the car. Currently, we are conducting tests on ply schedules across parts on the car to validate mechanical strength, with an ultimate goal of reducing mass of individual parts. By collecting a database of mechanical properties for different ply schedules, we can reference trends in data to help select an optimal ply schedule for a monocoque.
