Compression Molding of Composites
Compression molding is a widely employed technique in composite manufacturing, involving the use of heat and pressure to shape composite materials. In this process, a pre-measured amount of composite material, often in the form of sheets or pellets, is placed into a mold cavity. The mold is then closed and subjected to high pressure and temperature, allowing the material to conform to the shape of the mold. As the material compresses and solidifies, it forms the desired product. Compression molding is favored for its ability to produce complex shapes with high fiber volume fractions, ensuring strong and consistent composite parts.
