Balsa, honeycomb, foam and aluminum are the materials most commonly used as core in composite sandwich structures. Use of core increases thickness and stiffness of composite structures, with minimal weight penalty.
Reduces resin absorbed by core in VARTM (infusion) by up to 90% in rigid sheets and 50% in contourable (CK) core.
New sandwich core made using lightweight balsa veneers.
Over-Expanded Cell Aramid Honeycomb has a rectangular cell shape, thereby allowing the core to flex in one direction easily.
Designed to bridge the strength-to-weight gap between balsa and foam by providing a high-strength but lightweight and inexpensive intermediate.
