For more information of "Vacuum Assisted Resin Transfer", see the section below.
VART Process
The VART process involves several key steps:
- Mold Preparation: A mold is created to define the shape of the desired composite part.
- Material Placement: Dry fiber reinforcements are placed into the mold, followed by a release agent to prevent bonding to the mold surface.
- Vacuum Bagging: A flexible vacuum bag is sealed over the mold, creating a vacuum that draws the resin into the fiber matrix.
- Resin Infusion: A low-viscosity resin is introduced into the vacuum bag, saturating the fibers and displacing the air.
- Curing: The resin is allowed to cure under controlled temperature and pressure, resulting in a solid composite part.
Advantages of VART
- High Fiber Volume Fraction: VART enables the use of high fiber volume fractions, improving mechanical properties and reducing material costs.
- Reduced Void Content: Vacuum assistance minimizes void formation, resulting in stronger and more durable composite parts.
- Complex Shapes: VART can be used to produce complex shapes and intricate geometries that are difficult or impossible to fabricate using traditional methods.
- Automated Process: The vacuum bagging and resin infusion steps can be automated, reducing labor costs and improving repeatability.
Applications of VART
VART is widely used in various industries, including:
- Aerospace: Composite parts for aircraft, spacecraft, and satellites
- Automotive: Structural components and body panels for performance vehicles
- Marine: Hulls, decks, and other marine structures
- Sports Equipment: Golf clubs, tennis rackets, and other high-performance sporting goods
