Description
Premium end grain balsa is a natural core material that offers an exceptional blend of mechanical performance, cost-effectiveness, and sustainability. By orienting the grain of the balsa vertically through the sheet, this core achieves optimal compressive performance, leveraging the strength of wood along the grain. With a compressive strength of 12.8MPa, it ranks among the highest in strength-to-weight ratio composite core materials available.
Each core sheet is composed of individual 50x50mm blocks with a scrim backing, making them easy to form around single curvatures and ensuring excellent resin transmission during infusion and resin transfer molding processes. This product is compatible with all common resin systems.
Manufactured from sustainable sources, this end grain balsa core is produced with a focus on reducing environmental impact while supporting biodiversity. Typical applications include recreational equipment such as snowboards, marine hulls, decks, motorsport body panels, and architectural panels.
