Kafukufuku pa Kugwiritsa Ntchito Nsalu ya Basalt Twill Pogwiritsa Ntchito UAV
Ulusi wa Basalt: Momwe Imapangidwira, Kapangidwe Kake, ndi Momwe Imakhala Yolimba
Zinthu zachilengedwe komanso zopanda poizoni ulusi wa basalt imapangidwa posungunula ndi kujambula miyala ya mapiri ophulika. ulusi wa basalt, miyala ya basalt imatenthedwa kufika pa 1500°C isanakokedwe mu ulusi wopitilira kudzera mu platinum-rhodium alloy spinnerets. Ulusi wa basalt uli ndi makhalidwe abwino kwambiri chifukwa cha chiyambi chake cha geological: umapirira kutentha kosiyanasiyana, koma kugwira ntchito kwake kosalekeza pa 600°C kumaposa kwa matrix ambiri a resin ndi Ulusi wa GalasiKukana kwa ulusi wa basalt ku malo okhala ndi alkaline ndi acidic kumatsimikizira kuti umakhala nthawi yayitali m'malo ovuta monga chinyezi chambiri komanso mpweya wowononga pamitundu ina ya GFRP.
Kufufuza Mapangidwe a Twill Weave
Twill weave imapanga ma warp kapena weft floats otambalala omwe amapanga nsalu yomwe imavala bwino komanso yoyenera bwino. Nsalu za Twill N'zosavuta kuyika ndi manja m'zigawo za UAV zokhala ndi ma profiles ovuta opindika monga mpweya wolowera ndi mapiko kuposa nsalu zopanda ulusi ndipo izi zimapangitsa kuti ntchito yoyika ndi manja ikhale yosavuta komanso imachepetsa zolakwika monga makwinya kapena kusakhazikika bwino kwa ulusi. Ubwino wake ndi wakuti ingagwiritsidwe ntchito poyika vacuum assisted resin infusion molding (VARTM) ndi resin transfer molding (RTM).
Ubwino wa makina a kapangidwe ka twill ndikuti ma floats ake ataliatali amachepetsa crimp ya ulusi. Crimp ya ulusi iyenera kusintha mphamvu ya ulusi, zomwe zimathandiza kuti chophatikizikacho chigwiritse ntchito bwino mphamvu ya ulusi. Komabe, nsalu za twill sizili ndi ulusi wolumikizana monga nsalu wamba, zomwe zimapangitsa kuti modulus yawo yodulidwa ikhale yocheperako chifukwa cha kusinthasintha kwina kwa nsaluyo.
Mphamvu yolimbitsa mgwirizano wa kapangidwe ka twill pa kupirira kuwonongeka: Mafakitale a basalt fiber reinforced polymer (BFRP) Amadziwika kale kuti ali ndi kulimba kwambiri, kotero kuti njira zawo zolephera nthawi zambiri zimaphatikizapo kuchotsa ulusi wabwino kwambiri, mosiyana ndi kusweka kwa brittle. Pachifukwa ichi, mawonekedwe a twill amawonjezeranso izi. Kusinthasintha kwa nsalu ya twill kumapatsa mphamvu zambiri zoyamwa mphamvu pakagwa kugwedezeka. Kugawidwa kwa ulusi ndi madera ang'onoang'ono a pulasitiki kumawononga mphamvu zambiri zoyamwa. Motero, kulimba kwachilengedwe kwa BFRP, pamodzi ndi njira yake yoyamwa mphamvu chifukwa cha kapangidwe ka twill weave, kumapanga mphamvu yogwirizana pa kupirira kuwonongeka konse kwa kugunda, zomwe zimawonjezera kuyamwa kwa mphamvu kwa chinthu (SEA). Izi zimapangitsa nsalu ya BFRP twill kukhala yoyenera kwambiri pa magiya olowera a UAV kapena m'mphepete mwa mapiko ndi madera omwe mbalame zimagunda kapena zinyalala, kapena malo ena aliwonse omwe amawonjezera kwambiri kupulumuka kwa UAV m'malo ovuta ogwirira ntchito.
