Abstract Fiber reinforced polymers (FRP) provide favorable properties such as weight-specific strength and stiffness that are central for certain industries, aerospace or automotive manufacturing. Liquid composite molding (LCM) is a family of often employed, inexpensive, out-of-autoclave manufacturing techniques. Among them, resin transfer (RTM), offers high degree automation. Herein, textile p...

Vacuum-assisted resin transfer molding (VARTM) processes have been proven to be cost-effective manufacturing techniques for large composite structures. However, their use has been limited to single resin systems. A large variety Of composite structures requires multiple resins to serve different purposes while being integrated into a single structure. Significant environmental cost savings are ...

Carbon fiber reinforced polymers (CFRP) are light yet strong composite materials designed to reduce the weight of aerospace or automotive components – contributing reduced emissions. Resin transfer molding (RTM) is a manufacturing process for CFRP that can be scaled up industrial-sized production. It prone errors such as voids dry spots, resulting in high rejection rates and costs. At runtime, ...
