Vacuum Bagging

The advantages of vacuum bagging over traditional methods?

  • Mechanical pressure compacts the laminate, removing air, humidity, and excess resin, which can all compromise the curing process and the performance of the finished part.
  • This compaction improves the fiber-to-resin ratio, which is the key to maximizing the strength-to-weight advantages of any composite.

Some combination of these materials is essential for any successful vacuum bagging system. Before beginning any project, first determine the parameters of your part and your lay-up:

  • What is the size and shape of your part?
  • Does it have deep cavities or sharp corners?
  • What is the temperature range for my lay-up?

Answers to questions like these help you decide best materials for your part. If you're not sure which materials to buy, or if you have questions, give us a call as Rayplex® offers excellent customer service and knowledge of all our products.
