TBR® is a multifunctional polymer core designed for hard points within sandwich structures where through-bolting or point-loading would normally cause local crushing of low density sandwich cores. TBR® provides strength and performance for applications where there is a need for hard points and through bolting while maintaining lightweight construction. Typical applications include bolt transoms (outboard and inboard/outboard), deck cleat and railing bases winch pads, strut bases, and thru-hull pads. TBR® is available in three densities as standard sheets or fabricated kits. TBR® may contain up to 10% recycled content. It has a highly imidized chemical structure within its inter-penetrating polymer network. TBR® has a coarse cell structure designed for increased mechanical adhesion.Information provided by DIAB, Inc.
