ʻO nā mea hawewe-transmissive wela kiʻekiʻe he mea dielectric multifunctional e hiki ke pale i ke kamaʻilio, telemetry, alakaʻi, detonation a me nā ʻōnaehana ʻē aʻe o ka mokulele ma lalo o nā kūlana maʻamau. Hoʻohana nui ʻia ia i nā mokulele, nā missiles, nā kaʻa hoʻokuʻu a me ka hoʻi ʻana Ma nā kaʻa komo hou e like me nā satellite, hiki ke hoʻokaʻawale ʻia ka palapala noi i nā radomes a me nā puka makani antenna.
ʻO nā kūlana ana nui o ke kiʻekiʻe wela kū'ē i nā mea hoʻouna nalu he mau waiwai dielectric, thermal shock resistance a me mechanical properties, etc. ʻO nā mea i luna e pili ana i nā koi o ka laweʻana i ka nalu, ka wela wela a me ka halihali ukana, kēlā me kēia. ʻO nā mea hoʻouna nalu maʻamau i hoʻohana nui ʻia i nā fiber organik i hōʻike ʻia e nā fila aramid a me nā fibers inorganic i hōʻike ʻia e nā fiber quartz. ʻAʻole maikaʻi ke kūpaʻa wela, ka ikaika haʻahaʻa, a hiki i ka ʻelemakule a me ka deformation nā mea fiber organik.
ʻAʻole kūpono hou lākou no ka hana ʻana i nā mea hoʻouna nalu i ka mokulele. Ma waena o nā mea anorganic, ʻo ka quartz fiber he mea ʻano fiber inorganic me nā waiwai hoʻoili nalu maikaʻi a me nā waiwai dielectric.
Hiki i ka quartz fiber ke hana ma ke kaiapuni o 1050 ℃ no ka manawa lōʻihi. I ka manawa like, ma ka ʻāina o ke alapine kiʻekiʻe a ma lalo o 700 ℃, ʻo ka quartz fiber ka haʻahaʻa a me ka paʻa o ka dielectric mau a me ka nalowale o ka dielectric, a ma ka manawa like e paʻa ai ma mua o 70% ikaika, hiki ke hoʻohana ʻia. ʻO ka hawewe kiʻekiʻe-permeable ceramic matrix composite mea he inorganic fiber material i hoʻopili ʻia a he kiʻekiʻe kiʻekiʻe ka hana piha, ke kūpaʻa wela kiʻekiʻe, ke komo ʻana o ka nalu a me nā waiwai dielectric maikaʻi. Loaʻa i ka fiber Quartz nā ʻano o ka pale ʻana i ka corrosion. Ma waho aʻe o ka waika hydrofluoric a me ka waika phosphoric wela, ʻaʻohe hopena o ka wai a me ka gaseous halogen acids a me nā waikawa maʻamau a me nā kumu nāwaliwali, a ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai a me nā mea hoʻoheheʻe organik.
