Carbon foam—a stiff, porous structure formed from a web of carbon atoms—is the stuff of manufacturers’ dreams. The breakthrough material is strong but lightweight, non-flammable and able to maintain its performance at high temperatures, and capable of absorbing sound and radiation. This unique combination of traits means carbon foam is brimming with potential applications across military, aerospace, and commercial industries. It is ideal for aircraft and ship insulation, wall panels, stealth technology (to avoid radar detection), and more.

However, developing this extraordinary technology is not without challenges. It can be difficult for manufacturers to produce a strong, lightweight, environmentally-friendly carbon foam while keeping costs low.
