Explosion Protection System with Composite Reinforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to effectively protect structures from damage caused by explosions and subsequent fires, particularly in critical facilities like energy and military structures, due to inadequate blast suppression and fire extinguishing capabilities.
Innovation Solution
An explosion protection system comprising fire extinguishing chemicals that decompose to release gases creating a barrier, blast suppression chemicals for shock attenuation, and a reinforcement layer with high impact and tensile strength materials to support these chemicals, using materials like Spectra-shields, Kevlar, and glass fibers, and binders like epoxy and polyester.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional fire protection methods are used, then fire suppression is provided, but they fail to effectively protect against blast energy and shock waves from explosions
Solution Approach 1:
The patent applies composite materials by combining fire extinguishing chemicals, blast suppression chemicals, and reinforcement layers into a multi-layer protective coating system. This composite structure provides both fire suppression and blast attenuation capabilities that neither material could achieve alone, directly resolving the contradiction between fire protection and blast suppression reliability
2Object-affected harmful factors
If fire extinguishing chemicals are applied, then fire is suppressed, but they do not provide adequate attenuation of shock waves and blast energy
Solution Approach 1:
The patent merges fire extinguishing chemicals with blast suppression chemicals into a single integrated protective system. The fire extinguishing chemicals (ammonium phosphate, sodium bicarbonate) work together with blast suppression chemicals (precipitated silica, fumed alumina) to simultaneously address both fire suppression and shock wave attenuation, resolving the contradiction between these two protective functions
3Temperature
If protective coatings are applied to structures, then fire resistance is improved, but the coatings lack sufficient impact and tensile strength to withstand explosion forces
Solution Approach 1:
The patent incorporates reinforcement layers containing high-strength materials such as Spectra shields, Kevlar, glass fibers, and carbon fibers into the protective coating system. These reinforcement layers provide the necessary impact and tensile strength to withstand explosion forces while maintaining fire resistance properties, directly resolving the contradiction between fire resistance and mechanical strength
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively reduces blast energy and prevents fires by absorbing heat, releasing non-flammable gases, and blocking gases released by explosions, demonstrated by successful prototype tests showing reduced temperature, shock, and overpressure attenuation, and complete suppression of light emission and projectile penetration.
Implementation Method 1
fire extinguishing chemicals which under heat from explosion will decompose absorbing heat and releasing fire extinguishing gases
Implementation Method 2
