DIAB ProBalsa® LD7 Light Weight Balsa Wood  (discontinued **)
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.

Category Notes

Materials flagged as discontinued () are no longer part of the manufacturer’s standard product line according to our latest information. These materials may be available by special order, in distribution inventory, or reinstated as an active product. Data sheets from materials that are no longer available remain in MatWeb to assist users in finding replacement materials.

Users of our Advanced Search (registration required) may exclude discontinued materials from search results.

Some of the values displayed above may have been converted from their original units and/or rounded in order to display the information in a consistent format. Users requiring more precise data for scientific or engineering calculations can click on the property value to see the original value as well as raw conversions to equivalent units. We advise that you only use the original value or one of its raw conversions in your calculations to minimize rounding error. We also ask that you refer to MatWeb's terms of use regarding this information. Click here to view all the property values for this datasheet as they were originally entered into MatWeb.
