Laminated Fireproof Structural Panel for Hot Work Habitats
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hot work habitats are inflexible, cumbersome, and prone to breaches from fires or sparks, with modular systems using flame retardant fabric that is not designed to contain fires and has integrity issues when breached, and fireproof materials are difficult to stitch or secure effectively.
Innovation Solution
A composite panel comprising a layer of flexible structural material and a layer of flexible fireproof material, laminated in parallel planes, with the fireproof layer facing inward to contain fires and the structural layer facing outward for protection, using silicone adhesive and mechanical fixings like zips or rivets, and a fireproof fabric treated with amorphous silica coating for high temperature resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fireproof material is used for panels, then fire containment capability is improved, but ease of manufacture deteriorates due to difficulty in stitching and attaching fasteners
Solution Approach 1:
The patent applies composite materials by combining fireproof material with structural material to create a panel that integrates both fire resistance and structural integrity. The fireproof material layer provides fire containment while the structural material layer provides the necessary mechanical properties for stitching and fastener attachment, resolving the contradiction between fire safety and manufacturability
Solution Approach 2:
The panel is segmented into distinct functional layers: a fireproof material layer for fire containment and a structural material layer for mechanical strength and assembly. This segmentation allows each layer to be optimized for its specific function while working together as an integrated unit, enabling both fireproofing and ease of manufacture
2Ease of operation
If flame retardant fabric is used in modular habitats, then flexibility and ease of installation are improved, but fire containment capability deteriorates as the fabric cannot withstand high temperatures
Solution Approach 1:
The invention uses composite materials where the fireproof material layer provides high-temperature resistance for fire containment while the structural material layer maintains flexibility and ease of installation. This composite structure allows the habitat to be both flexible for easy assembly and fire-resistant for safety
Solution Approach 2:
The fireproof material is applied specifically to the inner surface of the panel where fire containment is most critical, while the structural material provides the outer layer for mechanical strength and flexibility. This local differentiation of material properties optimizes both fire safety and ease of installation
3Strength
If conventional galvanised sheeting and wooden panelling are used, then structural strength is improved, but flexibility and ease of installation deteriorate
Solution Approach 1:
The panel uses composite materials combining fireproof material with structural material that provides both high strength and flexibility. This allows the habitat to be constructed with strong panels that are yet easy to install and assemble, overcoming the limitations of conventional rigid materials
