APPLICATION NOTE: RTM / VACUUM INFUSION
GLASS SELECTION:
SI Veils and light weight reinforcements are engineered for RTM/VIP applications. Their electrical properties and corrosion resistance characteristics make them ideal for various applications. Veil is used on surface parts for outstanding finishes or in thin profiles. Widths are to customer’s specifications, allowing for less waste and lower manufacturing costs. Binder range percentages may also be specified, giving the designer greater flexibility.
Typically, Pearlveil-110 (Series 100 Binder), 20 Mil is used on the surface, while Pearlveil-110, ½ ounce may provide reinforcement in thin profiles. For complex shapes consider either Curveil-110 or Flexiveil-110. See Technical Data Sheets for options.

FEATURES:
SI Veils offer many features for RTM/VIP applications.
SI Veils offer many features for RTM/VIP applications.
• Excellent wet-out,
• Excellent electrical insulation properties,
• Excellent resistance to fiber wash,
• Long length rolls, reducing number of rolls in inventory,
• Custom specified binder range percentage,
• Highly corrosion resistant under acidic conditions,
• Contaminant free, making it safe for RTM/VIP,
• White in color, making it transparent in the finished part, and
• Glass is easily sanded for smooth part finishing.

OVERVIEW:
The Resin Transfer Molding (RTM) process is a Closed Mold Process in which reinforcements are placed between two matched mold surfaces. The mold is then closed and thermoset resins are injected into the mold at moderate pressures, commonly between 50 - 100 psi. RTM is typically employed for smaller production runs.
Vacuum Infusion Processing (VIP) is similar to RTM, utilizing vacuum assist for the resin injection. Another difference is that it normally uses a non-porous film in place of the top die.
The advantage in both processes is that the tooling costs are much less expensive than traditional tooling making eithera very good option for low volume part manufacturing.Finished parts include Fire Helmets, enclosures and table tops.
