摘要： Alined wood particles and an adhesive binder comprise the faces of a sandwiched, laminate-like structure formed in a one-step pressing and heating operation, the interior of which is made of randomly oriented wood particles and an adhesive binder, exhibiting light weight and greater bending strength than known particleboards constructed from heavy hardwoods such as red oak.

摘要： A lamina for a medium density structural board made from dimensioned wood flakes cut from a mixture of hardwood species and having a high retained internal bond strength is disclosed. The wood flakes are blended with a phenol formaldehyde resin having a major quantity of a low molecular weight fraction and a wax and then formed into a hot pressed product. The lamina may be used alone or as the core of a structural board having veneer, hardboard or plywood face panels. Three or more lamina may be formed into a structural board or used as the core of a board having veneer, hardboard or plywood face panels.
