Vacuum Infusion is not a Direct Replacement for Open Mold or RTM

Vacuum Infusion has continued to hold the spotlight of the FRP molding industry. In itself vacuum infusion (VARTM) is an excellent molding process. Producing products with high fiber load while offering a low entry investment, and is simply to educate staff on. However, many have stumbled with the hype that this "new" process is a drop in replacement for their current production. What are the differences between a product developed via open mold, closed mold (RTM, LRTM, HP-RTM, and vacuum infusion. Is vacuum infusion a drop in replace for your production?!

RTM, LRTM, & VARTM Glossary

Quick Link: A B C D E F G H I J K L M N O P Q R S T U V W X Y Z A- Ablative Plastic: Material that absorbs heat (with low material loss and char rate) through a decomposition process (pyrolysis) that takes place at or near the surface exposed to the heat. ABS: Acrylonitrile Butadiene Styrene (Thermoplastic Resin). Abrasion: Wearing away by friction. Glass is highly resistant to abrasion by other materials, but can be damaged through contact with itself. A lubricant is used during processing and fabrication to prevent abrasion. [...]

Demystifying the RTM Process

Resin Transfer Molding (RTM) is a low pressure, closed molding process which offers high-quality dimensional and surface finish composite moldings using liquid thermoset polymers reinforced with various forms of fiber reinforcements. Typically polymers of Epoxy, Vinyl Ester, Methyl Methacrylate, Polyester or Phenolic are used with fiberglass reinforcement. [...]
