Kutentha kwambiri kugonjetsedwa ndi mafunde amagetsi ndi zinthu zambiri za dielectric zomwe zingateteze kulankhulana, telemetry, chitsogozo, kuphulika ndi machitidwe ena a ndege pansi pa nyengo yabwino. Amagwiritsidwa ntchito kwambiri muzoyenda zam'mlengalenga, zophonya, kuyendetsa magalimoto ndi kubwerera Pamagalimoto obwereranso monga ma satelayiti, fomu yofunsira ikhoza kugawidwa m'mawindo a radome ndi antenna.
Miyezo yayikulu yoyezera kutentha kwambiri yolimbana ndi mafunde amagetsi ndi zida za dielectric, kukana kutenthedwa kwamafuta ndi makina amakina, etc. Zomwe zili pamwambazi zimagwirizana ndi zofunikira za kufalikira kwa mafunde, kutentha kwa kutentha ndi kunyamula katundu, motero. Zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizira ulusi wa organic woimiridwa ndi ulusi wa aramid ndi ulusi wachilengedwe woimiridwa ndi ulusi wa quartz. Zida za organic fiber zimakhala ndi kutentha kosasunthika, mphamvu zochepa, ndipo sachedwa kukalamba komanso kusinthika.
Salinso oyenera kupanga zida zotumizira mafunde mundege. Pakati pa zida za inorganic, quartz fiber ndi inorganic fiber material yokhala ndi mphamvu zotumiza mafunde komanso dielectric.
Ulusi wa quartz ukhoza kugwira ntchito m'malo a 1050 ℃ kwa nthawi yayitali. Panthawi imodzimodziyo, m'dera lafupipafupi komanso pansi pa 700 ℃, quartz fiber imakhala ndi dielectric yotsika kwambiri komanso yokhazikika kwambiri komanso yowonongeka, ndipo nthawi yomweyo imakhala ndi mphamvu zoposa 70%, ingagwiritsidwe ntchito. Kutentha kwambiri kwa mafunde a ceramic matrix composite material ndi inorganic fiber yomwe yakhala ikugwiritsidwa ntchito ndipo imakhala ndi magwiridwe antchito apamwamba, kukana kutentha kwambiri, kulowa kwa mafunde ndi zinthu zabwino za dielectric. Ulusi wa Quartz ulinso ndi mawonekedwe a kukana dzimbiri. Kuwonjezera asidi hydrofluoric ndi asidi otentha phosphoric, zina zamadzimadzi ndi mpweya halogen zidulo ndi zidulo wamba ndi zapansi ofooka alibe mphamvu pa izo, komanso insoluble m'madzi ndi zosungunulira organic.
