Composite Basalt Fabric Tent Liner Fire Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tent materials used by military personnel for large tents often release toxic gases and smoke when exposed to fire, melt, and can cause structural collapse due to air-filled support damage, failing to adequately protect the structure and its contents.
Innovation Solution
A composite tent liner composed of basalt fabric layers with a core, such as a basalt mat or reflective foil, which provides fire resistance without generating hazardous combustion products, and can be used to protect air-filled supports within a sleeve configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional tent materials are used to meet fire resistance ratings, then fire resistance is improved, but toxic gases and smoke are generated
Solution Approach 1:
The patent applies composite materials by combining basalt fabric layers with a core layer (basalt mat or reflective foil) to create a tent liner that provides fire resistance without generating toxic gases. The basalt fabric layers are secured to the core to form a multi-layer composite structure that achieves both fire protection and low smoke emission properties.
2Reliability
If conventional tent materials are used, then fire resistance is achieved, but materials melt and drip when exposed to fire
Solution Approach 1:
The patent applies parameter changes by selecting basalt fabric with specific weight parameters (about 12-19 oz./yd. sq.) and combining it with appropriate core materials to achieve optimal fire resistance and material stability. The composite structure maintains its composition stability under fire exposure through the selected material parameters and layer configuration.
3Strength
If air-filled supports are used in tent construction, then structural support is improved, but fire damage causes total collapse
Solution Approach 1:
The patent applies the intermediary principle by positioning the composite basalt liner between the fire source and the air-filled supports. The liner acts as a protective intermediary that shields the supports from fire damage, allowing the structural support function to be maintained while improving fire resistance reliability.
