Vacuum bagging is a technique used in various industries, particularly in composite manufacturing. It involves placing a material, such as fiberglass or carbon fiber, inside a plastic bag and then removing the air from the bag using a vacuum pump. This process helps to compress the material, ensuring a tight fit and reducing the presence of air bubbles, which can weaken the final product. The vacuum creates an even pressure across the surface of the material, allowing for better resin distribution and improved bonding. This method is commonly used in the production of items like boat hulls, aerospace components, and automotive parts, enhancing their strength and durability.
