Mhando uye hunhu hwesangweji chimiro chekugadzira tekinoroji muFRP kugadzira maitiro

Iyo ine hutano uye yakagadzikana budiriro yechero indasitiri inzvimbo inodiwa yekusimudzira kwakagadzikana kweiyo indasitiri chain. Iko hutano uye hunogara huripo hwechinyakare composite zvinhu (girazi fiberreinforced plastic) indasitiri inofanirwa kuve yakavakirwa pane hutano uye kusingaperi kusimudzira kwayo kumusoro kwegirazi fiber uye unsaturated polyester resin maindasitiri. Indasitiri yegirazi fiber yapedza kubatanidzwa kwemaindasitiri, ichigadzira indasitiri yepasi rose inokwikwidza yeChina, ukuwo indasitiri isina unsaturated resin ichangotanga kurongekazve kweindasitiri, uye shanduko dzinotevera dzichaunzawo mabhenefiti kuindasitiri yechinyakare inoumbwa zvinhu. zvine simba guru.

Sandwich zvimiro zvinowanzoumbwa zvinogadzirwa nezvikamu zvitatu zvezvinhu. Iyo yepamusoro uye yakadzika mitsara ye sandwich composite zvinhu ndeye yakakwirira-simba uye yakakwirira-modulus zvinhu, uye yepakati layer ndeye yakakora lightweight zvinhu. TheFRP sandwich chimiroichokwadi kusanganiswa kwezvinhu zvakaumbwa uye zvimwe zvinhu zvisingaremi. Kushandiswa kwesangweji chimiro ndechekuvandudza kushandiswa kunobudirira kwezvinhu uye kuderedza uremu hwechimiro. Kutora danda-slab zvikamu semuenzaniso, mukugadzirisa kwekushandisa, zvinodikanwa kusangana nezvinodiwa zvesimba uye kusimba. Hunhu hweFRP zvinhu zvine simba rakawanda, Modulus yakaderera. Naizvozvo, kana imwe girazi faibha yakasimbiswa epurasitiki zvinhu inoshandiswa kugadzira matanda uye slabs kusangana nezvinodiwa zvesimba, kutsauka kunowanzo hombe. Kana iyo dhizaini yakavakirwa pane inobvumidzwa deflection, iyo simba ichapfuudzwa zvakanyanya, zvichikonzera marara. Chete nekutora dhizaini yechimiro chesangweji ndipo kupokana uku kunogona kugadziriswa zvine musoro. Ichi zvakare chikonzero chikuru chekuvandudzwa kwechimiro che sandwich.

Nekuda kwesimba repamusoro, huremu huremu, kusimba kwepamusoro, kusadzivirirwa kwemagetsi, kuvharwa kwemagetsi uye kufambisa kwema microwave kweiyo FRP sandwich chimiro, yakashandiswa zvakanyanya mundege, makombi, spacecraft uye modhi, mapaneru edenga muindasitiri yezvendege uye indasitiri yezvemuchadenga. Deredza uremu hwechivako uye uvandudze basa rekushandisa. The transparentgirazi fiberyakasimbiswa epurasitiki sandwich panel yakashandiswa zvakanyanya mumatenga ekuvhenekesa ezvirimwa zveindasitiri, zvivakwa zvakakura zveveruzhinji uye greenhouses munzvimbo dzinotonhora. Mumunda wekuvaka ngarava uye zvekufambisa, FRP sandwich zvimiro zvinoshandiswa zvakanyanya muzvikamu zvakawanda muFRP submarines, minesweepers, uye yachts. Iyo FRP mabhiriji evanofamba netsoka, mabhiriji emugwagwa, mota nezvitima, nezvimwe zvakagadzirirwa uye kugadzirwa munyika yangu zvese zvinotora FRP sandwich chimiro, inosangana nezvakawanda-kuita zvinodiwa zvehuremu hwekureruka, kusimba kwepamusoro, kusimba kwepamusoro, kupisa kupisa uye kuchengetedza kupisa. Muchivharo chemheni chinoda kufambisa microwave, iyo FRP sandwich chimiro chave chinhu chakakosha icho zvimwe zvinhu hazvigone kuenzaniswa nazvo.
