DIAB ProBalsa® PB Standard Balsa Wood
Categories: Other Engineering Material; Composite Core Material; Wood and Natural Products; Wood

Material Notes: ProBalsa is a high quality composite core material made from end-grain balsa wood. The end grain, micro-honeycomb structure offers exceptional shear and compressive strength. In addition ProBalsa offers good fatigue properties, high thermal and sound insulation and low FST properties.

ProBalsa is best suited for dynamic structures where performance and efficiency are paramount. All ProBalsa core materials are particularly easy to work using conventional woodworking tools. They can be drilled, milled, turned and sawn to close tolerances. ProBalsa can be used in hand lay-up, vacuum bag and infusion applications. It is also suitable for elevated temperature cure prepreg systems. ProBalsa Plus is a premium version of ProBalsa where the surface is micro sanded and treated with a special surface primer to reduce resin absorption during lamination.
