Vacuum bagging is a process for making composites that takes a typical hand lay-up one step further. Once layers of reinforcement and resin are laid-up by hand, the laminate is sealed in an air-tight environment, like a vacuum bag, and connected to a vacuum source. Vacuum is applied, creating mechanical pressure on the laminate throughout the cure cycle.

Vacuum bagging offers a number of distinct advantages over traditional methods. The added 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. In doing so, it improves the fiber-to-resin ratio, which is the key to maximizing the strength-to-weight advantages of any composite.

Vacuum Fittings

Vacuum Fittings

Fibre Glast offers a full selection of industrial-grade fittings, connectors, and tubing for use with most vacuum bagging and resin infusion applications. Regardless of set-up, the products in this category are designed to work interchangeably.


Vacuum Infusion

Vacuum Infusion

Our vacuum infusion supplies include a number of trusted names in flow media, including EnkaFusion, Lantor Soric, and Divinymat, as well as HDPE, LDPE, tubing, and more. This category is designed to help you find the media that's right for your project.


Sandwich Core

Sandwich Core

Build higher strength-to-weight ratios for your laminate with lightweight, structural layers of sandwich core. Nomex® Honeycomb, end-grain balsa, and foam in a variety of densities and formats make up a wide selection from which to build parts with increased flexural strength and modulus.


Tools

Tools

Our category of vacuum bagging supplies is complete with the tools necessary to set-up and monitor the vacuum bagging or resin infusion process. From controlling air leaks to making solid connections, these tools will make your job easier. Explore the products that are right for your project.


Vacuum bagging materials and fundamentals will translate to vacuum infusion (also called resin infusion), which is an even more advanced manufacturing process. Rather than using vacuum pressure to remove excess air and resin from within the laminate, infusion uses vacuum pressure to drive resin into the laminate.

Both vacuum bagging and vacuum infusion will require some items outside the scope of traditional hand lay-up, including the vacuum bag, peel ply or release film, and a quality vacuum pump. Your lay-up will determine the size of your vacuum bag, and it's advisable to match the size of your vacuum bag with pump ratings. You can access vacuum bagging materials, pumps, fittings, tools, and more from the vacuum bagging category at FiberGlast.com.

Vacuum bagging is not necessarily a complex process and will, ultimately, produce laminates that are stronger and lighter.
