Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing composite materials require expensive and time-consuming surface preparation processes like grinding and multiple primer layers for printing or lacquering, which complicates their finishing and increases costs.
Innovation Solution
A composite material comprising a carrier with a textile surface structure laminated on both sides, featuring a finally hardened B-stage binder, allowing for direct printing or lacquering without pre-working, and optionally including functional materials for enhanced properties like electrical conductivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional composite materials are used for finishing steps like printing or lacquering, then the surfaces require expensive and time-consuming pre-working (grinding, primer coating), but the invention enables direct printing without such preparatory measures
Solution Approach 1:
The textile surface structure is prepared in advance with a B-stage binder that creates an optimally smooth surface during the composite material manufacturing process itself. This preliminary action eliminates the need for subsequent grinding and primer coating operations, allowing direct printing or lacquering immediately after composite material production.
2Manufacturing precision
If multiple preparatory measures (grinding, primer coating) are applied to achieve suitable surface quality, then the surface can be printed or lacquered, but the process becomes expensive and complex
Solution Approach 1:
The invention merges the surface preparation function into the composite material manufacturing process itself. The textile surface structure with B-stage binder serves dual purposes: it provides structural reinforcement and simultaneously creates the required smooth printing surface, eliminating the need for separate grinding and primer coating operations.
Solution Approach 2:
The B-stage binder undergoes a controlled transformation from a partially cured state during manufacturing to a fully hardened state that provides the desired surface smoothness. This parameter change in the binder's curing degree creates the optimal surface quality directly during composite material production, eliminating multiple preparatory steps.
3Manufacturing precision
If abrasive measures are used to smooth surfaces for printing, then the surface quality improves, but additional processing steps and costs are incurred
Solution Approach 1:
The textile surface structure is prepared in advance with a B-stage binder that creates an optimally smooth surface during the composite material manufacturing process itself. This preliminary action eliminates the need for subsequent grinding and primer coating operations, allowing direct printing or lacquering immediately after composite material production.
