- KutenthaUL94 V-0; Miyezo yamoto ya NASA/ESA
- KuthamangitsaASTM E595 yogwiritsidwa ntchito yotsekedwa
Nkhani Yodziwika Bwino (Kutentha Kwambiri + Misa)
- chandamale: ΔT ≥ 10–15°C kudutsa fuselage khoma
- Sintha: PI kanema (25 μm) + 20 mm / 4 kg/m³ thovu la melamine + khoma lachitsulo
- chifukwa: ~ 0.8 kg / 10 m² core mass - chitetezo cha ntchito ziwiri
- Kabati Yokwera Ndege ndi Avionics Bay Interior Insulation
Chidule cha Ntchito
Zipinda za ndege zamalonda ndi zipinda za avionics zimafunikira kuchepetsa phokoso, kutonthoza kwa kutentha, ndi chitetezo cha moto. 4 kg/m³ thovu la melamine limachepetsa phokoso la kanyumba, limalepheretsa kuyanika, komanso limakwaniritsa miyezo yolimba yoyaka moto.
Kutsimikizira & Kuyesa

- Thanzi/ChitetezoISO 16000 VOC mpweya
Nkhani Yodziwika Bwino (Phokoso + Kutentha)
- Area10 m², makulidwe: 15 mm → Voliyumu 0.15 m³
- Melamine Foam (4kg/m³)kulemera kwake: 0.6kg PU Foam (20kg/m³): 3.0 kg
- chifukwa:~80% yopepuka, phokoso la kanyumba limatsika ≥ 4 dB (A)
- Phokoso la Ndege Zankhondo ndi Kuchepetsa Siginecha Yotentha
Chidule cha Ntchito
Ndege zankhondo zimafuna zida zomwe kuchepetsa phokoso la kanyumba, chepetsa siginecha ya infrared, ndi kupirira madera ovuta kwambiri. 4 kg/m³ thovu la melamine limakwaniritsa zolingazi popanda kusokoneza malipiro.
Kutsimikizira & Kuyesa
- Acoustic: Mayesero a NVH osagwira ntchito, oyenda panyanja, komanso oyendetsa
- Kutentha: UL94 V-0 / FAR 25.853 / MIL-STD chitetezo chamoto

- Thermal/IRISO 8301 / ASTM C518 + IR siginecha kusanthula
- Kukhalitsa Kwachilengedwe: Kuyenda pang'onopang'ono, chinyezi, chifunga chamchere
Nkhani Yodziwika Bwino (Phokoso + Kukhathamiritsa Katundu)
- Area10 m², makulidwe: 20 mm → Voliyumu 0.2 m³
- Chithovu cha Melamine (4 kg/m³)kulemera kwake: 0.8kg Thonje wa Acoustic (18kg/m³): 3.6 kg
- chifukwa: ~ 78% yopepuka, ≥ 5 dB(A) kuchepetsa phokoso, ~ 3% kutsika kwa siginecha ya IR
Ubwino Wapadziko Lonse wa Aerospace OEMs
- Kuchepetsa Kulemera: Kufikira 80% kupepuka kuposa zida zachikhalidwe
- Ntchito Zapawiri: Thermal + acoustic mu gawo limodzi
- Compliance: Kukumana ndi UL94 V-0, FAR 25.853, ASTM E595, ndi zina zambiri
- kwake: Imapirira kugwedezeka, kutentha kwambiri, chinyezi
- Kuchita Mtengo: Kuchepetsa ndalama zoyendetsera ntchito
