Advanced composites are the key to unlocking the next generation of industrial performance. However, the high cost of entry and specialized knowledge requirements have traditionally restricted carbon fiber fabrication to aerospace giants and elite racing teams.
MACC Composites (Manufacturing and Advanced Composite Consulting) was founded to break down these barriers, selling composite engineering excellence as a service. This page details how we transfer high-performance engineering concepts to the medical, automotive, and defense sectors.

The Pivot: Applying Racing Rigor to Diverse Sectors
For over a decade, Predator Cycling served as our R&D lab, allowing us to master silicone molding, optimize resin-to-fiber ratios, and build a data-driven factory model.
Through MACC Composites, we apply these same high-fidelity fabrication techniques to external industries. The mechanical properties required to build a world-class track bicycle — vibration damping, structural rigidity, and weight optimization — translate directly to medical prosthetic limbs, ruggedized defense enclosures, and electric vehicle chassis.
Lean Composites: Democratizing Aerospace Standards
Entering the composite manufacturing space traditionally requires multi-million dollar autoclaves and clean room setups. MACC addresses this bottleneck through a Lean Composites approach:
- Out-of-Autoclave (OOA) Curing: We developed custom thermal cycles that achieve aerospace-grade structural strength using high-precision ovens and vacuum bagging, reducing capital costs for clients.
- Traceable Quality Systems: We map every composite part to a digital thread (GUID), providing clients with timestamped autoclave logs, material batch tracking, and technician records to satisfy ISO 9001 and AS9100 requirements.
KEY TAKEAWAY: Adhering to strict digital traceability logs allows small-to-medium enterprises to qualify for high-value aerospace and defense procurement contracts.
Cross-Industry Case Studies
1. Medical Device Prototyping
Carbon fiber is highly radiolucent, making it ideal for medical imaging equipment. MACC assisted a medical startup in transitioning an imaging table assembly from heavy aluminum to carbon composites, using generative design to reduce weight by 45% while maintaining strict deflection limits.

2. Automotive Weight Reduction
For electric vehicles (EVs), weight reduction is directly linked to battery range. We consulted for Tier-2 automotive suppliers to replace heavy steel chassis brackets with validated carbon composite parts, running Finite Element Analysis (FEA) to guarantee structural integrity over a 100,000-mile lifetime.
Summary: The Scalable Materials Sandbox
MACC Composites provides small-to-medium enterprises with the materials, validation math, and quality tracking needed to innovate with advanced composites.
Key takeaways:
- Democratized material access: Small-volume supplies allow startups to prototype without large minimum orders.
- Process optimization: Out-of-Autoclave cycles reduce manufacturing costs while maintaining material strength.
- Cross-sector engineering translation: Apply custom racing engineering to solve medical, automotive, and defense challenges.
Q&A
Q: What is the main advantage of carbon fiber over aluminum in medical imaging? A: Carbon fiber allows X-rays and imaging beams to pass through with minimal interference (radiolucency), resulting in clearer scans while maintaining structural support.
Q: Do you assist with material sourcing? A: Yes. From our logistics center in Lebanon, Tennessee, we supply specialized pre-preg carbon fiber and tooling supplies to boutique workshops and makers.
