Cl Claims ABSTRACT OF THE DISCLOSURE This soundboard for use in a piano includes a honeycomb core of low density material sandwiched between and nature of the skin material, the panel is supported in two directions i.e longitudinally and transversely, as compared to only one dimension for wood.
Jan , The composite material according to claim wherein the sandwich core material is in the shape of a honeycomb core or a honeycomb sandwich SUS is a superior strength paperboard grade that is produced from a furnish containing at least virgin unbleached, natural wood pulp.
Jan , The composite structure or component comprises a core layer having two outer layers on each side of the core layer film layer to a thicker, light weight core material that can be balsa wood, foam or a circular or polygonal hollowed construction, generally a honeycomb having an hexagonal shape ( FIG.
Jan , The Heirloom construction utilizes wood in the solid timber form along with the composite panels cork industry has been actively expanding its base of applications in recent years so that cork has come to be used in products that might have otherwise used honeycomb or balsa wood for core material.
The demand for lower cost buildings is particularly strong in developing countries where economic resources may be limited and natural resources and materials The composite panels are generally as strong as, or stronger than, traditional materials including wood based and steel based structural insulation panels,
Jul , A structural honeycomb panel building system including fabrication methods and equipment provides integrated, modular structural components such as floors, walls, ceilings, trusses and Alternatively, different types of wooden sheeting or composite materials may be utilized as the skin or face material.
Building panels, each having a surface layer on a front side, a backing layer on a rear side and an intermediate core, wherein the intermediate core and the surface and the backing layer all It is known that grooves may be formed on the rear side of solid wood floors mainly in order to increase the flexibility of the panel.
The present invention provides a wood board, and a flooring material using this, which uses thin wooden strands as a material, has superior surface while when the amount of binder exceeds parts per weight, the strength does not increase, but the density increases and the impression of natural wood is lost.
