Composite Material Manufacturing Using B-Stage Binder Lamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing composite materials for construction and furniture applications lack optimal mechanical stability, workability, and weight reduction, necessitating the development of improved methods for manufacturing composite materials that combine wood-based carriers with textile surface structures and binders.
Innovation Solution
A method involving the use of wood-based carriers, such as plywood or laminated wood, combined with textile surface structures reinforced by B-stage binders, where the textile surfaces are pre-strengthened using chemical or thermoplastic binders, and optionally applied with functional materials like flameproofing agents or pigments, followed by lamination under pressure and heat to achieve final hardening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If traditional composite materials are used, then mechanical stability is sufficient, but weight reduction and workability are not optimized
Solution Approach 1:
The patent uses composite materials consisting of a carrier (wood-based, paper, cork, cardboard, or mineral plate), a textile surface structure (non-woven fabric) impregnated with B-stage binder, and functional materials. This multi-component composite structure optimizes the balance between weight reduction and mechanical stability by combining lightweight materials with strengthening elements.
Solution Approach 2:
The textile surface structure is selectively applied to specific surfaces of the carrier where strength and stability are needed, while the core carrier material provides the base weight reduction. The B-stage binder is concentrated in the textile layer where it provides local reinforcement without adding excessive weight throughout the entire composite.
2Strength
If multiple materials are laminated to improve mechanical properties, then strength increases, but manufacturing complexity and processing difficulty increase
Solution Approach 1:
The textile surface structure is pre-impregnated with B-stage binder before lamination, and the carrier is prepared in advance with its surface properties optimized. This preliminary preparation allows the actual lamination process to proceed more efficiently without requiring complex in-process adjustments, improving both strength and ease of manufacture.
Solution Approach 2:
The patent optimizes parameters such as the weight per unit area of the textile surface structure (10-500 g/m²), the binder content (5-50% by weight), and lamination conditions (temperature, pressure, time) to achieve the desired balance between mechanical properties and workability. By carefully controlling these parameters, the composite can be manufactured efficiently while maintaining high strength.
3Strength
If textile surface structures are strengthened with binders, then mechanical stability improves, but processing efficiency and manufacturing costs increase
Solution Approach 1:
The textile surface structure is pre-impregnated with B-stage binder in a controlled manner before final assembly. This preliminary impregnation allows for optimized binder distribution and reduced binder content compared to applying binder during final lamination, thereby improving processing efficiency while maintaining the required mechanical stability.
Solution Approach 2:
The patent specifies optimal binder content ranges (5-50% by weight of the textile surface structure) and uses B-stage binder which has partially cured properties, allowing easier handling and processing compared to fully cured binders. This parameter optimization reduces processing time and energy requirements while achieving the necessary mechanical strength.
