Which Composite Core Material is Right for Me? Top Three Questions to Ask
Composite core materials are used to complete the function of engineered structures by providing strength, stiffness and continuity throughout without drastically increasing weight. Whether bonded between two composite skins to form a sandwich panel or over-molded with self-skinning flexible foam or decorative cover, core material serves as the central member or foundation of a structure. However, with so many viable material options available, it’s important to first identify the criteria the material needs to meet to help narrow down the decision-making process.
The best way to identify the material criteria for your application is to first answer the following questions:
- Which material properties are most important to your application?
Design engineers typically focus on the core material’s design or performance needs, property requirements needed to fit those needs and the end cost. For instance, honeycomb, which is commonly used in composite core panel applications, has excellent strength to weight ratio, but can be susceptible to moisture and is also on the expensive end of the spectrum. Narrowing down the properties specifically needed for the application while also reviewing cost is a vital first step. - Which material properties are most important to your application?

Once you’ve decided on your core material and manufacturing process, you must verify that it is the most cost-effective option for your budget. There are several core materials available that offer a product that may be considered over-engineered for the application. Instead of paying a premium for capabilities you do not need, focus on a material that provides the properties and capabilities that fit the necessary function for your project.
