Composite Material Is Suitable For New Energy Automotive Batteries
Nov 13, 2024
The high temperature 1400 degree fireproof fabric composite material is suitable for new energy automotive batteries and other fields
The traditional fire-retardant fabric is a specially treated glass fiber satin fabric with tight structure and high temperature resistance, which can well protect the object from the thermal point and spark zone, and completely prevent burning or isolate burning. Traditionally, the thickness of the fire retardant fabric is only 1.0mm, and the high temperature resistance can reach 550℃.
Their main components include natural fire resistant fibers such as asbestos, glass fiber fabric and after flame retardant finish with fire resistant fabrics. Mainly used for guard clothing, military uniforms, military equipment with fabrics and tents.
SVT fire retardant fabric, is a fiberglass fabric with an expanded fire retardant coating, which will form a fire protection layer in case of fire. In order to meet the higher fire protection requirements, this fire resistant fabric can be applied to strengthen the battery case housing, adapted to the epoxy resin construction system, by RTM or SMC process methods to add to the whole or sandwich, instead of aluminum. The thickness of the SVT anti-thermal runaway impact fireproof fabric is only 0.8mm, and the high temperature resistance can reach
1400℃.
It can realize the improvement of lightweight battery pack and fire protection function.
SVT fireproof fabric can be integrated with composite materials to replace the traditional aluminum substrate, and develop a new generation of fireproof functional battery packs for electric vehicles
Product advantage
· Can withstand 23 seconds of particle bombardment at 1400 degrees Celsius
· Can improve the toughness of the structure
· Excellent elongation and bending properties
· Extremely thin material thickness (customizable)
· Freer plasticity
· Suitable for various epoxies
Advantages over traditional materials
Used for epoxy resin system to make battery pack shell, 40% lighter than aluminum, but can improve the toughness of 5 times.
Excellent fire performance and can withstand the flame impact, in the close distance of 1400℃ high temperature flame impact 23 seconds without any deformation and burned through, the same temperature and distance, aluminum only needs 6 seconds. It is suitable for the production application of automated RTM or SMC materials, as an alternative solution of high temperature resistant glass fiber cloth against thermal runaway impact.
Foamed aluminum carbon fiber composite material
Glass fiber composite SMC composite
SVT fireproof fabric can be widely used in a variety of processes of closed mold construction, and has been specially optimized for lithium-ion batteries of new energy vehicles due to particle bombardment and high temperature
Construction technology
SVT fireproof fabric, can be used as fiber cloth using RTM construction process applied to SMC material processing. Due to the addition of fireproof fabric in the shell of the battery pack made of SMC material, it can achieve effective weight reduction and enhance the strength of the shell and greatly improve the fire resistance. Therefore, there is no need for additional means to protect the shell against fire.
