Pultrusion composite materials, also known as pultruded composites, are a type of composite material that is manufactured through the pultrusion process. Pultrusion is a continuous manufacturing process in which reinforcing fibers, such as fiberglass or carbon fiber, are impregnated with a polymer resin and then pulled through a heated die. The die shapes the composite material into the desired profile, such as rods, tubes, or beams, while simultaneously curing the resin. This results in a high-strength, lightweight, and durable composite material with excellent mechanical properties. Today we will lead you to understand the pultruded composite materials produced by our company, and explain to you the production principles of pultruded composite materials and the application scenarios of pultruded composite materials.
Our company produces pultruded composite materials, which are categorized into unsaturated polyester pultruded components and epoxy pultruded rods based on the resin used. Here are the specific differences between these two products:
1.Different Resin Materials:
Unsaturated polyester pultruded components are made by combining fiberglass yarn as the base material with unsaturated polyester resin. Epoxy pultruded rods, on the other hand, are made by combining fiberglass yarn as the base material with epoxy resin. The main difference lies in the type of resin used.
2.Different Colors:
Unsaturated polyester pultruded components are primarily available in red and white colors, while epoxy pultruded rods are typically green in color.
3.Different Temperature Resistance:
Unsaturated polyester pultruded components have a temperature resistance rating of Class B, capable of withstanding temperatures up to 130°C. Epoxy pultruded rods, on the other hand, have a temperature resistance rating of Class F, capable of withstanding temperatures up to 155°C. Epoxy pultruded rods exhibit higher temperature resistance compared to unsaturated polyester pultruded components.
These are the specific differences between these two products. However, apart from these differences, both products have similar applications. Now that you have an understanding of these two products, I will guide you through some of the manufacturing principles and applications of pultruded composite materials.
1.Fiber Reinforcement:
The process begins with the reinforcement of fibers, such as fiberglass or carbon fiber. These fibers, known for their high strength and stiffness, are pulled from spools and guided through a resin bath.
2.Resin Impregnation:
In the resin bath, the fibers are thoroughly impregnated with a liquid resin. This impregnation process ensures that the fibers are fully saturated with the resin, which will provide strength and durability to the final composite material.
3.Preforming:
Once the fibers are impregnated, they are guided through preforming guides that help align the fibers in the desired orientation. This step ensures that the fibers are properly arranged for optimal strength and performance.
4.Mold Design and Function:
The aligned fibers then pass through a heated steel mold, commonly referred to as a die. The die is carefully designed to shape the composite material into the desired profile, such as rods, tubes, or beams. It plays a crucial role in maintaining the shape, dimensions, and surface finish of the final product.
5.Curing:
As the fibers pass through the die, the resin undergoes a curing process. This process may involve the application of heat or the use of ultraviolet light, depending on the specific resin system. The curing solidifies the resin, creating a rigid and durable composite material.
6.Tension Control:
Throughout the pultrusion process, tension is applied to the fibers to ensure they remain straight and properly aligned. This tension control helps achieve the desired mechanical properties and minimizes defects in the final product.
