Uphando malunga nokusetyenziswa kwe-UAV kwi-Basalt Twill Fabric
I-Basalt Fiber: Indlela Eyenziwe Ngayo, Ulwakhiwo Lwayo, Nokuba Ihlala Iqinile Kangakanani
Izinto zendalo nezingeyotyhefu ifayibha yebasalt iveliswa ngokunyibilikisa nokuzoba amatye entaba-mlilo. imicu ye-basalt, i-basalt ore itshiswa ukuya kuthi ga kwi-1500°C ngaphambi kokuba itsalwe kwimisonto eqhubekayo ngokusebenzisa ii-spinnerets ze-platinum-rhodium alloy. I-basalt fiber ineempawu ezigqwesileyo ngenxa yemvelaphi yayo yejoloji: imelana nobushushu obahlukeneyo, kodwa ukusebenza kwayo okuqhubekayo kwi-600°C kudlula oko kwee-resin matrices ezininzi kunye Ifayibha yeglasis. Ukumelana kwe-basalt fiber kwiindawo ezine-alkaline kunye ne-asidi kuqinisekisa ubomi bayo obude kwindawo enzima efana nokufuma okuphezulu kunye nobukho begesi erhabaxa kwiindidi ezithile ze-GFRP.
Ukuhlola iiPateni zeTwill Weave
I-Twill weave ivelisa ii-warp okanye ii-weft floats ezinde ezivelisa ilaphu eligudileyo nelihambelana kakuhle. Amalaphu eTwill Kulula ukuzibeka ngesandla kwiindawo ze-UAV ezineeprofayili ezigobileyo ezintsonkothileyo ezifana nee-air intakes kunye nee-wing fairings kunee-plain-weave fabric kwaye oku kwenza lula inkqubo yokubeka ngesandla kwaye kunciphisa iziphene ezifana nemibimbi okanye ukungalungelelani kweefayibha. Inzuzo yayo kukuba ingasetyenziswa kwi-vacuum assisted resin infusion molding (VARTM) kunye ne-resin transfer molding (RTM).
Iingenelo zoomatshini zesakhiwo se-twill kukuba ii-long floats zaso zinciphisa i-fiber crimp. I-crimp ye-fiber kufuneka iphucule ukusebenza kakuhle kokuguqulwa kwamandla okutsalwa kwe-fiber, okuvumela i-composite ukuba isebenzise ngokupheleleyo amandla e-fiber. Nangona kunjalo, amalaphu e-twill akanazo iintambo ezininzi ezidityanisiweyo njengee-plain weave, ezidla ngokunciphisa kancinci i-in-plane shear modulus yazo ngenxa yokuguquguquka okongeziweyo kwelaphu.
Isiphumo sokuqinisa ngokubambisana kwesakhiwo se-twill ekunyamezeleni umonakalo: Iikhompawundi ze-basalt fiber reinforced polymer (BFRP) sele zaziwa ngokuba nokuqina okuphezulu, kangangokuba iindlela zazo zokusilela zihlala ziquka ukukhupha ifayibha engengobungozi, ngokungafaniyo nokuqhekeka okubuthathaka. Kule meko, ijiyometri ye-twill iyayiphucula ngakumbi le nto. Ukuguquguquka okwandisiweyo kwelaphu le-twill kuyinika amandla aphezulu okufunxa amandla kwiimeko zomthwalo onzima. Ukusasazwa kweefayibha kunye neendawo ezincinci zokuguqulwa kweplastiki kususa amandla aphezulu oxinzelelo. Ngenxa yoko, ukuqina kwendalo kwe-BFRP, kunye nendlela yayo yokufunxa amandla ngenxa yesakhiwo se-twill weave, kuvelisa isiphumo sokusebenzisana kunyamezelo lomonakalo onzima, nto leyo ephucula ukufunxa amandla athile ezinto (i-SEA). Oku kwenza ilaphu le-BFRP twill libe lilungelo elihle kakhulu kwiigiya zokufika ze-UAV okanye imiphetho ekhokelayo yamaphiko kunye neendawo ezivezwe kukubetheka kweentaka okanye impembelelo yokungcola, okanye nayiphi na enye indawo ekhulisa kakhulu ukusinda kwesakhiwo se-UAV kwindawo yokusebenza enzima.
