A Brief Overview of GRP Production Processes and Applications
Glass Reinforced Plastic (GRP) is a lightweight, high-strength, and corrosion-resistant composite material widely used in construction, transportation, chemical, and marine industries. Its exceptional performance makes it a popular choice for various industrial applications. Depending on the product’s purpose and production requirements, different forming processes can be selected. This article provides a brief introduction to the common production processes for GRP. Lamination The lamination method is a traditional and versatile production process. It is suitable for producing complex shapes and small-batch products, such as storage tanks, irregular shells, and small containers. This method requires minimal equipment and offers high flexibility. Process Steps: 1. Clean the mold surface and apply a release agent. 2. Apply gel-coat and resin onto the mold surface. 3. Manually lay fiberglass mats or fabrics and saturate them with resin. 4. Use a roller to compact the layers and eliminate air bubbles.
