Our pulwinding process combines continuous pultrusion with precision filament winding, integrating longitudinal reinforcement fibers with angle-wound fibers in a resin matrix to deliver maximum bidirectional strength, hoop rigidity, and dielectric performance tailored to each specific application.
We create custom pulwound products that are lightweight, torsionally rigid, and mechanically superior. They are also corrosion resistant, wear resistant, and provide excellent electrical insulation. Depending on your application, our engineers will collaborate with you to develop an optimized combination of resins and fibers to meet your exact structural specifications. Contact us today to discuss how our custom pulwound composite solutions can address your engineering challenges.
Types of Resins Used in Our Pulwound Products:
- Epoxy Resins – Most commonly used due to their superior structural strength, high interlaminar shear performance, and excellent electrical insulating properties.
- Vinyl Ester Resins – Highly chemical- and corrosion-resistant resin ideal for harsh, acidic, or marine operating environments.
- Polyester Resins – Cost-effective resin providing solid baseline mechanical performance for standard, general-purpose applications.
Types of Fibers Used in Our Pulwinding Process:
- Glass Fibers roving and mat – Widely used for balanced tensile/flexural strength, impact resistance, and high electrical insulation.
- Polyester Fibers – Used for surface protection, enhanced dielectric performance, and cost-efficient reinforcement layers.
