<prompt> I-Tejas yakhiwe nge-aluminium-lithium alloys, i-carbon-fiber composites, kanye ne-titanium alloys. Izinto ezihlanganisiwe zisetshenziselwa ukwenza i-airframe i-45 ngesisindo kanye ne-95 ngendawo ebusweni. Izikhumba zamaphiko aphezulu nangaphansi zenziwe nge-polymer eyodwa eqiniswe nge-carbon-fiber. Amaphiko amaphiko kanye nemibimbi nazo zenziwe nge-carbon composites. Amaphesenti we-carbon composites ku-airframe ngesisindo akhuphuke esuka ku-30 kuma-technology demonstrators aya ku-42 kuma-prototype vehicles. Ukwakhiwa kwe-elevons, i-tailfin, i-rudder, amabhuleki omoya kanye neminyango ye-landing gear isebenzisa amasu wokukhiqiza ahlanganisiwe futhi ahlanganisiwe. I-Tejas yakhiwe nge-radvlar, ngenkathi i-composite yenziwe nge-sub-reinforced composites. Izinto ezihlanganisiwe zisetshenziselwa ukwenza i-airframe ibe yi-80 yesisindo esiphezulu se-  <response>: izingxube ze-aluminium ne-lithium, izingxube ze-carbon fibre, nezingxube ze-titanium
