Core Material

Core Material

Core materials play an important role in the composite industry. They are intricate structures that are bonded to two thin, stiff sheets on either side, forming what is known as a “sandwich structure”. Sandwich structures are used in a multitude of contexts, such as in building construction, aircraft and vehicular construction, as well as refrigeration engineering.

Our core materials support high-quality sandwich structures, as they are composed of non-woven components that boast remarkable workability as well as being cost and weight-efficient. Laminates that utilize our core materials carry the advantage of being light-weight and able to withstand high impact and fatigue

Contact our specialists to inquire about how we can make our quality core materials suitable for your business requirements.
