Rapid Pultrusion and Forming of Thermoplastic Composite Rebar for Reinforcement of Cementitious Materials
RPI ID: 2022-004-401
Innovation Summary:
Thermoplastic composite rebar is formed by embedding continuous fibers into a polymer matrix using controlled extrusion and curing. The resulting structure offers high strength-to-weight ratio and corrosion resistance. It is designed to replace steel rebar in concrete applications, especially in marine and corrosive environments. The process supports scalable and customizable manufacturing.
Challenges / Opportunities:
Steel rebar is heavy and prone to corrosion, limiting its lifespan in infrastructure. This composite alternative addresses those issues while maintaining mechanical integrity. It enables sustainable construction and reduces maintenance costs. The technology is suitable for modular and on-site fabrication.
Key Benefits / Advantages:
✔ Corrosion-resistant composite material
✔ Lightweight and durable
✔ Compatible with concrete reinforcement
✔ Sustainable and recyclable
✔ Customizable manufacturing
Applications:
• Civil infrastructure
• Marine construction
• Earthquake-resistant buildings
Keywords:
