throughbonded

Throughbonded refers to a specific manufacturing process used to create composite materials. In this method, a core material is joined to one or more outer layers by creating a physical bond that extends through the thickness of the composite. This is distinct from processes where layers are bonded only at their surfaces.

The throughbonding process typically involves impregnating a core material with a resin system that then cures, forming a solid matrix that encapsulates and bonds the outer layers to the core. This creates a monolithic structure with enhanced mechanical properties. Different techniques can be employed for throughbonding, including resin infusion, prepreg lay-up followed by curing under pressure, or pultrusion processes where the composite is pulled through a heated die to consolidate the materials.

The primary advantage of throughbonded composites is their high interlaminar strength and stiffness. Because the bond extends through the entire thickness, there is a reduced risk of delamination, which is a common failure mode in layered composites. This makes throughbonded materials suitable for applications requiring high structural integrity and resistance to shear forces, such as in aerospace components, automotive parts, and sporting goods. The precise method of throughbonding is often tailored to the specific materials being used and the desired performance characteristics of the final product.
