ʻO nā mea hoʻoheheʻe wela ma ka mokulele, nā mea wela ma ka radar.
1. Hoʻokomo ka CMC composite i kahi kaʻina hana hou, multilayer copper-molybdenum-copper, paʻa ka hoʻopaʻa ʻana ma waena o ke keleawe a me ka molybdenum, ʻaʻohe wahi āpau, a ʻaʻohe mea e hoʻoheheʻe ʻia i ka wā o ka ʻōwili wela a me ka hoʻomehana ʻana, no laila ka ikaika paʻa ma waena ʻOi aku ka maikaʻi o ka molybdenum a me ke keleawe, i loaʻa i ka mea i hoʻopau ʻia ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa a me ka conductivity thermal maikaʻi loa;
2. He maikaʻi loa ka lakio molybdenum-copper o CMC, a ua hoʻomaluʻia ka hoʻololi o kēlā me kēia papa i loko o 10%;ʻO ka mea SCMC kahi mea i hoʻohuihui nui ʻia.ʻO ka hoʻonohonoho hoʻonohonoho ʻana o ka mea mai luna a lalo: ʻo ka pepa keleawe - ka pepa molybdenum - ka pepa keleawe - ka pepa molybdenum... ka pepa keleawe, hiki ke haku ʻia i 5 mau papa, 7 mau papa a i ʻole nā papa.Ke hoʻohālikelike ʻia me CMC, loaʻa iā SCMC ka helu haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa a me ka conductivity thermal kiʻekiʻe.
