TRANSONITE™ is a customized product designed for the end use. The core material may vary (foam, balsa, phenolic, etc.), and a wide range of fibers, fabrics, and resins can be utilized for the composite skin. The overall thickness can vary up to 4 inches. Individual skin thickness may vary, and the density of 3-D fibers is adjustable. This creates the ideal sandwich panel that can meet all strength, weight, and cost demands - regardless of the application.






The 3-D through-thickness fibers in TRANSONITE™ provide greater durability than conventional sandwich panels. Delamination, a common problem in traditional sandwich materials, is virtually eliminated with the 3-D reinforcements that tie the face sheets together. Additionally, TRANSONITE™ is one of the only panel products available which can be produced at any length, and width up to 8.5 feet. This provides large clean surfaces with no edges or seams.

TRANSONITE™ can be manufactured using a wide variety of core materials, reinforcements, fabrics, and resins.

TRANSONITE solid plate


TRANSONITE™ Bar Stock is as strong as steel yet lighter. It can be pultruded up to 1 inch think, up to 8 feet wide, and at any length required.

Bar Stock made with the TRANSONITE™ process, contains structural fibers spanning three orthogonal directions. This solid composite is ideal for machining small components, as it is quasi-isotropic.

This Bar Stock is ideal for use in corrosive and marine industries, and can easily be fabricated with CNC equipment using diamond tools or water jet. Additionally, because it has 3-D fibers, machined components hold together.
