Composite Materials for Structural and Mechanical Applications

Lightweight, strong, stiff, corrosion resistant, with significant design flexibility 

Why consider composites as a structural material?

Thermoset composites are prized for their robust properties and design flexibility. From world class weight adjusted strength and stiffness to corrosion resistance, to toughness and fatigue resistance, composites have found use in the most demanding mechanical and structural applications under, on, and above the earth.

Your custom composite is within reach

There’s nothing exotic about custom materials. We develop them every day. Our chemists and engineers have produced hundreds of materials for thousands of applications—more than 200 grades. Our significant technical data and in-house testing capability is the starting point for your new application, accelerating the design process.

Destined for repeatable performance

When design engineers come to us for a material solution, they also get the manufacturing capability and capacity to deliver it.

From standard products to those that are uniquely produced for a single application, our structural materials are manufactured in accordance with ISO and PSM standards. Our production approach minimizes variation relative to other composite manufacturing techniques, resulting in materials that are produced economically in large volumes.
