Embodiment Construction

[0063] first reference Figure 1A and 1B A first embodiment of a lignocellulosic material component is described.

[0064] The lignocellulosic material part 10 is formed from a single sheet 11 of lignocellulosic material which is partially delignified and impregnated with an impregnating polymer.

[0065] As shown below, the lignocellulosic material was only partially (but not fully) delignified.

[0066] The lignocellulosic material is preferably any kind of wood, such as oak, walnut, poplar, ash, maple or sapele.

[0067] The lignocellulosic material is for example a wood coupe, and preferably a longitudinal cut (radial longitudinal cut CLR or tangential longitudinal cut CLT) or a transverse cut (CT).

[0068] Wood comprising lignin and a network of cellulose and hemicellulose is partially delignified.

[0069] Depending on the type of wood used, the proportion of lignin removed can be higher or lower.

[0070] As a non-limiting example, the proportion of lignin removed ...

Abstract

A part made from lignocellulosic material (10) is formed from a single sheet (11) of partially delignified lignocellulosic material impregnated with an impregnation polymer. The part (10) comprises at least one curved portion having a double curvature surface. The part made from lignocellulosic material is produced by a production method implementing a thermoforming step. Use in particular for producing wood veneer structures.

Description

technical field [0001] The present invention relates to parts of lignocellulosic material, methods of manufacturing such parts and methods of converting such parts of lignocellulosic material. Background technique [0002] The use of lignocellulosic materials (especially wood) for components is highly regarded due to wood's natural beauty, warm colors and special touch. It ennobles structures decorated with wood veneered parts. [0003] Therefore, wood veneers are currently very popular for furniture, interior architecture and the interior decoration of motor vehicles, or in the aviation or nautical fields. [0004] Various forms of wood veneering have also been sought, such as by shaping planks to create curved surfaces. However, wood veneers are fragile and have crack lines or cracks when formed and strongly bent. [0005] Wood parts formed of wood boards having a thickness of 0.1-1 mm and impregnated with resin in order to provide the board with a certain flexibility a...
