balsa core

3A Composites balsa core material selected by US Navy
The company’s BALTEK SB balsa core has received ABS Certification and is currently the only balsa core material approved for the US Navy shipbuilding programs.  

satellite shipping container

Composite container protects satellites — on the ground
Cored composites add the strength, smoothness and portability needed for a container built to ship satellites over air, land and water.

Big composite container protects vital satellite
Before they experience the vibrations of launch and the rigors of the space environment, satellites first have to make it to the launch pad. Pagnotta Engineering Inc. (PEI, Exton, PA, US) was called upon by Orbital ATK (Dulles, VA, US) to design a shipping box to protect Orbital ATK’s GEOStar-3 geosynchronous satellite bus structure, during shipment.
