Airtech - Your Trusted Manufacturer of Vacuum Bagging and Kitting Solutions
At Airtech, the processes PREPREG / AUTOCLAVE, GLASS LAMINATING, RESIN INFUSION, OVEN CURE, and WET LAY UP, are commonly associated with the manufacturing of composite materials, especially in the aerospace and automotive industries. These processes involve the use of advanced materials and techniques to create strong, lightweight, and durable composite structures. Below is a brief description of each process: PREPREG / AUTOCLAVE: Prepreg refers to reinforcing fibers (such as carbon or glass fibers) pre-impregnated with resin. In the autoclave process, these prepreg materials are laid up in a specific orientation and then cured under high temperature and pressure in an autoclave. This ensures a uniform distribution of resin and optimal bonding between the fibers, resulting in a high-strength composite material. GLASS LAMINATING: Glass laminating involves the layering and bonding of glass fabrics using resin to create a composite material. The process may include impregnating the glass fibers with resin, stacking multiple layers, and then curing the assembly to achieve the desired mechanical properties. Glass laminates are known for their excellent strength, stiffness, and impact resistance. RESIN INFUSION: Resin infusion is a manufacturing method where dry fibers are placed in a mold, and resin is then injected or drawn through the fibers to saturate and impregnate them. The infused material is then cured to create a solid composite structure. This process is known for producing parts with high fiber volume fractions, resulting in enhanced mechanical properties. OVEN CURE: Oven curing is a thermal process used to cure composite materials after the resin has been applied. The assembly is placed in an oven where controlled heat is applied to facilitate the curing reaction of the resin. This process helps in achieving the desired material properties, such as strength and rigidity, while removing any remaining solvents or volatiles. WET LAY UP: Wet lay-up involves manually applying layers of resin-impregnated fabric onto a mold. The process allows for flexibility in fabric orientation and resin application. After the lay-up is complete, the composite is typically cured at ambient or elevated temperature. Wet lay-up is a versatile method used for producing composite parts with a wide range of shapes and sizes. Visit: https://airtech.com/

The molding of pre-impregnated fabrics and filminfused
fabrics typically requires the use of elevated
temperatures and vacuum consolidation under a
vacuum bag in either Oven or Autoclave.
Airtech provides a comprehensive range of vacuum
bag materials and equipment required curing in
Autoclave and Oven, including:
Bagging Films
Vacuum Bag Sealant Tapes
Release and Bleed-out Films
Release Fabrics and Peel Plies
Breather and Absorption Fabrics

The vacuum bagging process is employed in glass
laminating to apply even pressure during bonding.
Vacuum bags apply even pressure up to
atmospheric pressure, 14.7 lbs. per square inch
(2,000 lbs. per square foot). This predictable and
consistent pressure application consolidates
laminates.
Airtech range of products offers vacuum bagging
consumables, vacuum fittings and ancillary
products for the application of vacuum bags to this
process.
Our range provides cost effective, quality assured
materials with reliable performance.
Resin Infusion is a process by which vacuum draws
resin into a dry fiber laminate in a one sided mold. A
rigid or flexible film membrane is placed over the
top and sealed around the mold periphery. Resin
infusion is considered a “Closed Mold Process”.
The benefits of resin infusion when compared to
non-vacuum bag curing of composite laminates
include:
Better fiber to Resin ratio
Stronger laminate
Low void content
Reduce operator exposure to harmful emissions
Reduce resin usage due to pre-compacted
fabric
Faster Ply lay-up
