Permitted Polymer Composite Materials

In Simple Terms

F1 teams can use various advanced composite materials (combinations of resins and reinforcing fibers) to build their cars, with specific limits on carbon fiber strength and density. This rule ensures all teams use similar quality materials while allowing flexibility in how they construct their vehicles.

• Multiple resin types allowed including epoxy, polyester, and thermoplastics for the matrix (binding material)
• Carbon fiber reinforcement is limited to ≤550GPa modulus, ≤7100MPa strength, and ≤1.92g/cm³ density
• Teams can also use aramid, glass, polyethylene, and other alternative reinforcing fibers
• Rules ensure competitive balance by controlling material properties across all teams
