The insulation materials in the flat-top area of the roof and the end wall area of the vehicle are composed of aerogel, glass fiber wool, sound insulation felt, etc.; the fireproof materials of the underframe are made of aerogel + glass fiber cloth.
The use of aerogel felt has significantly improved the heat insulation and sound insulation performance of the High-speed train, greatly reduced heat loss, and achieved remarkable energy-saving effects.
Adopting the customized aerogel insulation blanket. the excellent high-temperature insulation performance can withstand the burning flames of related materials for more than 30 minutes. This solution can ensure that when the power cabin catches fire, the fiber composite board above does not get quickly ignited, thus guaranteeing passengers sufficient time for safe evacuation. The installation and construction of the aerogel insulation board is also very convenient. It comes with a backing adhesive, and the fireproof material is pasted under the composite board and fixed with code nails from the other side.
