Composite sandwich core materials are used in the construction of composite panels made up of three layers: a low-density core sandwiched between two thin, high-strength skins. These materials are used in a variety of applications, including boat building, aerospace, and construction, due to their high strength-to-weight ratio, durability, and stiffness. Composite sandwich cores are typically made of lightweight materials such as foam, balsa wood, or honeycomb, which provide the necessary strength and stiffness while minimizing weight. The skins are typically made of high-strength materials such as fiberglass or carbon fiber, which provide the necessary strength and stiffness to the sandwich panel.
By employing sandwich core materials in your part or mold, you can achieve much higher flexural strength and flexural modulus than using skin laminates alone.

Sandwich Core materials from FibreGlast.com include:
- Nomex® Honeycomb--Offers the very best strength-for-weight ratio in this category; flexible, fire retardant, and delivers good impact resistance.
- End Grain Balsa--Conforms to practically any simple curve and most gradual curves.
- Foam--Includes sheets of vinyl and polyisocyanurate, as well as mix-and-pour foam; all are closed cell and resist water, gas, and oil.
All the Sandwich Core materials in this category are compatible with epoxy, vinyl ester, and polyester resins, and can be used for most lay-up techniques, including vacuum bagging and infusion.
To see how Sandwich Core is used during the vacuum bagging process, visit the Learning Center and read Vacuum Bagging Equipment & Techniques. You can also view An Introduction to Sandwich Core Materials on the Fibre Glast Blog.
