Not every composite repair requires autoclave curing.

For large structural carbon fiber repairs where full autoclave processing is impractical, Vacuum Assisted Resin Transfer Molding, VARTM, provides an advanced and reliable solution.

At Pfaff Technologies, VARTM is used for large-area composite restoration that demands uniform resin distribution and structural consistency.

When Is VARTM Used in Automotive Carbon Repair?

VARTM is ideal for:

• Large carbon body panels
• Diffuser assemblies
• Rear structural sections
• Extended laminate repairs

This process allows controlled resin infusion under vacuum pressure, ensuring consistent wet-out across wide surface areas.

How Vacuum Infusion Restoration Works

The process includes:

• Surface preparation and ply removal
• Precise dry fiber layup
• Vacuum bagging
• Controlled resin infusion
• Cure cycle monitoring
• Dimensional validation

By using vacuum pressure to distribute resin, we eliminate air voids and ensure structural bonding across the repair zone.

Structural Integrity Without Full Autoclave Requirements

While autoclave curing is critical for prepreg components, VARTM offers a highly effective solution when dealing with:

• Large panels
• Complex geometry
• Integrated structures

The result is restored stiffness, load-bearing strength, and aerodynamic integrity.

Every VARTM repair is documented and inspected to meet OEM-level standards.

For luxury vehicle owners and restoration shops, this ensures confidence in both performance and resale value.

At Pfaff Technologies, composite repair is engineered, not improvised.
