Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The extrusion efficiency of fiber layers in ceramic matrix composites, arranged in single layers with insufficient toughness and stability, is affected when extruded with a single extrusion gun for staggered arrangement.
Innovation Solution
A continuous fiber curing extrusion device with a main support frame and multiple guide rails, featuring a ceramic flux extrusion gun and two fiber flux extrusion guns, allows for longitudinal and transverse alternate extrusion of fibers on ceramic flux layers, enhanced by a segmentation mechanism and cooling mechanism to improve stability and toughness.

Engineering Contradiction Analysis
1Productivity
If a single extrusion gun is used for staggered arrangement of fiber layers, then the device complexity is reduced, but the extrusion efficiency and fiber layer stability are insufficient
Solution Approach 1:
The patent divides the single extrusion function into multiple specialized extrusion guns (first fiber flux extrusion gun, second fiber flux extrusion gun, and ceramic flux extrusion gun). Each gun is responsible for a specific extrusion task, allowing parallel operation and improved overall extrusion efficiency while maintaining manageable system complexity through functional segmentation.
Solution Approach 2:
The patent introduces multi-dimensional movement capabilities with guide rails arranged in different orientations (first guide rail, second guide rail, third guide rail). The extrusion guns can move along multiple axes and perform staggered arrangement in three-dimensional space, transforming the extrusion process from a single-line sequence to a multi-dimensional parallel operation system.
2Reliability
If fiber layers are arranged in single layers, then the device complexity is reduced, but the toughness and stability of the composite material are insufficient
Solution Approach 1:
The patent segments the fiber reinforcement function into multiple layers with different orientations. The first fiber flux extrusion gun extrudes fibers in one direction while the second fiber flux extrusion gun extrudes fibers in a staggered arrangement, creating multi-layered fiber reinforcement that significantly improves toughness and stability compared to single-layer arrangements.
Solution Approach 2:
The patent creates a composite structure by combining multiple fiber layers with different orientations and a ceramic matrix. The staggered arrangement of fiber layers from different extrusion guns forms a reinforced composite material system where the synergistic effect of multi-directional fibers significantly enhances the overall mechanical properties and reliability of the ceramic matrix composite.

AI summary
A continuous fiber curing extrusion device based on additive manufacturing ceramic composites includes a main support frame. A top inner wall of the main support frame is simultaneously mounted with a first guide rail, a second guide rail, and a third guide rail. The first guide rail is parallel to the second guide rail, the second guide rail is perpendicular to the third guide rail, a ceramic flux extrusion gun is movably connected to the first guide rail, and a bottom end of the ceramic flux extrusion gun is provided with a segmentation mechanism. One end of the ceramic flux extrusion gun is connected to a ceramic flux storage bin through a first connecting pipe, and a first fiber flux extrusion gun and a second fiber flux extrusion gun are movably connected to the second guide rail and the third guide rail respectively.
