<prompt> Ge e le gore Tejas e agilwe ka aluminium-lithium alloys, carbon-fiber composites, le titanium alloys. Composite materials make up 45 of the airframe by weight and 95 by surface area. Composite materials are used to make a lighter aircraft by weight and 95 by surface area. Mašapo a maphego a ka godimo le a ka tlase a dirwa go tšwa go karolwana e tee ya carbon-fiber reinforced polymer. Maphego a maphego le maphego a maphego le ona a dirilwe go tšwa go carbon composites. Peresente ya carbon composites ka go airframe ka boima e hlatlogile go tšwa go 30 ka go thekenolotši ya go bontšha go fihla go 42 ka go prototype ya dikoloi. Go agwa ga elevons, tailfin, rudder, air brakes le mamati a gear a go fologa a šomiša mekgwa ya go dira ya co-cured le co-bonded.  <response>: ditlaleletši tše di nago le di-aluminium-lithium, ditlaleletši tša carbon-fibre le ditlaleletši tša titanium
