Product Introduction

 

Aramid Aluminium Foil Composite Fabric

Aramid aluminium foil composite fabric represents an innovative multifunctional textile material integrating high-performance fibre properties, metallic shielding capabilities, and composite processing advantages. Its core comprises a composite structure of aramid base fabric (aramid 1313 or aramid 1414), an aluminium foil layer, and a functional adhesive layer. It finds extensive application in sectors demanding stringent resistance to high temperatures, radiation, and tear strength, such as aerospace, defence, industrial protection, and new energy.
I. Core Composition and Composite Process
1. Core Components
Aramid Base Fabric: Serving as the foundational load-bearing layer, it primarily employs two high-performance aramid fibres:
Para-aramid: Excels in high-temperature resistance, flame retardancy, and chemical corrosion resistance. Withstands prolonged exposure up to 200°C and momentary temperatures exceeding 400°C. Does not melt or drip when exposed to fire, self-extinguishing upon removal from flames, while maintaining excellent textile processability and flexibility.
Para-aramid: Building upon high-temperature resistance, it combines ultra-high strength (five times that of steel wire) and high modulus (two to three times that of steel wire). It offers outstanding cut resistance and tear strength, making it suitable for applications demanding superior mechanical properties.
Aluminium foil layer: As the functional core layer, premium aluminium foil is bonded to the base fabric via vacuum metallisation or direct lamination. Typically 0.01-0.05mm thick, it primarily provides thermal reflection, electromagnetic shielding, and waterproof/vapour barrier properties.
Bonding Layer: Utilises specialised adhesives resistant to high temperatures and ageing, ensuring the aramid base fabric and aluminium foil remain bonded under extreme conditions without compromising the material's overall heat resistance.
2. Composite Processes
Vacuum Aluminium Coating: Directly forms an aluminium foil layer on the aramid base fabric surface via vacuum deposition technology. Requiring no additional adhesive, this yields a lighter, thinner fabric with superior flexibility, ideal for applications with stringent thickness requirements.
II. Core Performance Characteristics
The properties of aramid-aluminium composite fabric result from the synergistic combination of aramid fibre and aluminium foil functionalities, offering the following distinct advantages:
1. Exceptional High-Temperature Resistance and Thermal Insulation
The aramid base fabric's inherent heat resistance provides fundamental thermal protection, enabling stable long-term operation in 200-300°C environments.
The aluminium foil layer reflects infrared radiation and thermal radiation, significantly reducing heat conduction. Combined with aramid's insulation properties, the fabric achieves superior thermal protection efficiency compared to pure aramid fabrics, effectively shielding personnel or equipment from harm caused by flames, high-temperature steam, and thermal radiation.
2. Superior Mechanical Properties
Composite fabrics based on aramid 1414 exhibit tensile strength ≥2000N/5cm and tear strength ≥500N. Their cut resistance far surpasses traditional cotton or polyester fabrics, even withstanding penetration by sharp objects, making them ideal for high-strength protective gear.
Composite fabrics using aramid 1313 base fabric exhibit slightly lower strength but superior flexibility, facilitating easier sewing and wearability.
3. Waterproof, Vapour-Barrier and Chemical-Resistant
The seamless, dense aluminium foil layer provides waterproofing and vapour barrier properties, effectively blocking moisture and acid/alkali gas permeation.
Aramid fibres resist most acids and alkalis (excluding strong oxidising acids) and organic solvents. The composite fabric maintains stable performance in chemical environments without degradation or deformation.
4. Flame Retardancy and Environmental Sustainability
Aramid is inherently flame-retardant, while aluminium foil is non-combustible. Neither releases toxic gases when exposed to fire.
The material is recyclable and meets environmental standards.
III. Primary Application Fields
1. Industrial Safety Protection
High-temperature workwear: Protective suits, heat-resistant aprons, and gloves for industries such as metallurgy, foundries, glass processing, and power plants, effectively shielding personnel from thermal radiation and flame exposure.
Firefighting equipment: Used as outer layers or thermal barriers in firefighting suits, extending firefighters' operational endurance in high-temperature fire scenes.
2. Aerospace and Defence
Aircraft interior materials: Such as cabin insulation layers and engine compartment fire shields, combining high-temperature resistance, thermal insulation, and flame retardancy to enhance flight safety.
3. New Energy and Electronics Industries
New energy vehicles: Used in battery pack insulation covers and engine compartment fire barriers to prevent high-temperature diffusion during battery thermal runaway, improving overall vehicle safety.
4. Construction and HVAC Industry
Building insulation materials: Employed in fireproof insulation layers for high-rise structures and roof insulation layers, offering combined flame retardancy, thermal insulation, and waterproofing.
HVAC duct insulation: Fabricated as external protective layers for ductwork, reflecting heat loss while preventing moisture penetration of the insulation core.
