What Is Pultrusion?

pultrusion technology
Pultrusion stands as a highly automated technique within the composites industry, setting itself apart from manual lay-up methods by reducing dependence on labor. Consequently, an increasing number of profiles are being re-engineered to capitalize on pultrusion technology. The core materials in this process typically include fiberglass and thermoset polymer resin.

The essence of pultrusion technology lies in pulling reinforcing fibers and matrices through a heated die, a method that heats reinforcement fibers like glass or carbon fiber within a resin matrix. As this composite material is extruded through the die, it forms profiles with uniform cross-sections. These profiles are integral to various industries for their structural components. Pultrusion stands out from other fabrication methods for its efficiency in crafting complex shapes swiftly and economically while preserving superior mechanical attributes such as tensile strength and resistance to corrosion. It also boasts a reduction in material waste, as it consistently produces parts at a rapid pace without the need for additional finishing processes. Moreover, pultrusion allows for the flexible customization of designs without the burden of costly tooling, as the reinforced plastic can be shaped into a wide array of forms using the same setup.

Thanks to this process, profiles are produced that are not only durable and boast a high strength-to-weight ratio but also offer an extended service life with significant savings in life-cycle costs.

The primary FRP structural composite profiles produced include:

  • Structural elements like beams, channels, angles, tubes, rods, and plates
  • Wall, roof, and decking panels
  • Cable instrumentation trays
  • Strut support systems
  • Gratings
  • Ladders and handrails

These applications demonstrate the versatility and efficiency of pultrusion in meeting the demands of various structural requirements.

  • FRP Rebar

    FRP rebar, or fiberglass reinforced polymer rebar, is a spirally wound structural reinforcement made from glass fiber roving and resin. It was developed as a superior alternative to steel rebar in concrete, offering benefits like being lightweight, corrosion-free, non-conductive, and durable.

  • bwfrp pipe

    BWFRP pipes typically consist of a three-layer structure, with the inner and outer layers being cross-woven and the middle layer being reinforced with hoops and longitudinal reinforcements.

  • pullwinding pipe

    The pultrusion process involves winding carbon fibers or fiberglass at a specific angle, impregnating the carbon fibers with resin, polymerizing the carbon fibers in a heated mold to form tubes, and then cutting them to the desired length.

Pultrusion is a continuous manufacturing process used for producing fiber-reinforced plastics with a constant cross-section. The process involves pulling fibers or woven/braided strands through a resin bath or injecting resin into an impregnation chamber connected to a heated die, where the resin cures and hardens into the final product. The reinforcement materials, such as mats made of continuous fiber filaments, are often used in this process to provide strength and stability to the final product.

The mats used in pultrusion can vary in complexity, from simple continuous strand mats to more complex fabric weaves. Advanced mats may include a combination of different fiber orientations—such as 45, 90, or 0 degrees—to meet specific mechanical and structural requirements dictated by the end-use application. These orientations affect the strength, stiffness, and other mechanical properties of the final product.

Pultruded mats and products find applications across various industries, including construction, where they are used for reinforcements, profiles, and stiffening bars; in the electrical industry for dielectric structures; in the automotive sector for structural components; and in many other sectors where high strength, chemical resistance, and durability are required.



Reinforcing fibers undergo a mechanical process where they are drawn into a resin bath, ensuring that each strand is fully saturated with the polymer resin, achieving thorough impregnation. This step is crucial as it ensures that the fibers are completely coated with the resin, which is essential for the structural integrity and performance of the final composite material. The meticulous saturation process is designed to optimize the adhesion between the fibers and the resin, forming a strong bond that is vital for the durability and strength of the end product.

Fibers drenched in resin are drawn through a die engineered with exacting precision, featuring an entry point and an internal cavity that mirrors the final product’s configuration. Within this heated steel die, the composite material takes shape and undergoes the curing process. As the thermoset composite emerges from the die, it is then trimmed to the specified length, resulting in a completed component.

Why is Pultrusion Used for Structural Composites?

Pultrusion is utilized for structural composites due to its ability to produce components with a consistent cross-section and high strength-to-weight ratio. This manufacturing process aligns fibers in a unidirectional manner, which is ideal for creating structural components that require high tensile strength along the length of the component. The resins used in pultrusion, such as polyester, polyurethane, vinylester, and epoxy, provide environmental resistance, including corrosion, UV, and impact resistance, while the glass fibers contribute to the strength and fire safety of the products.

Additionally, pultrusion is an energy-efficient and resource-saving technology, making it economically and environmentally favorable. It’s capable of using both thermosetting and thermoplastic polymers, with recent advancements allowing for the use of thermoplastic matrices like polybutylene terephthalate (PBT) and polyethylene terephthalate (PET), which are cleaner ecologically and offer nearly unlimited recycling potential. The demand for pultruded materials is growing due to their high chemical, dielectric, and strength stability, which are essential for various industries, including construction, aerospace, electrical engineering, and automotive.

The process has been further refined to allow not just for straight profiles but also for curved ones through modifications like the Radius-Pultrusion, which is particularly beneficial in the automotive industry. These advancements in pultrusion technology cater to the increasing demand for materials that can provide enhanced performance in complex applications.

Every one of these sectors poses distinct and demanding circumstances that necessitate dependable materials and consistent performance. For more details and support, feel free to reach out to us.
