Lightweight Wood-Based Composite Panel

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a method for making a lightweight wood-based sandwich board. The process involves placing top and bottom cover layers around an intermediate layer, then compressing the assembly while ensuring the foaming of the inner layer only happens after compression. This approach improves the production and structural qualities of the sandwich board.

Use CasesContent extracted from patent full text and abstract with AI.

• Construction of interior wall panels and partitions
• Furniture manufacturing (e.g., lightweight tables, shelves)
• Building prefabricated housing components
• Vehicle interiors or RV furnishing
• Acoustic panels in public or commercial spaces

BenefitsContent extracted from patent full text and abstract with AI.

• Reduces overall weight of construction materials
• Improves mechanical stability and strength of the boards
• Allows for efficient manufacturing with good bonding between layers
• Potential for better insulation properties due to the foamed intermediate layer
• Reduces material usage and costs compared to traditional solid wood or particle boards

Patent Abstract

The invention relates to a process for producing a sandwich board, comprising the following steps: providing an upper covering layer, providing a lower covering layer, providing an intermediate layer arranged between the upper and lower covering layers, compressing the upper and lower covering layers, and foaming the intermediate layer, in which process no foaming of the intermediate layer takes place at the start of compacting the upper and lower covering layers.
