Chinhu chinosimbisa ndicho chinhu chinotsigira chigadzirwa cheFRP, icho chinonyanya kusarudza hunhu hwemuchina wechigadzirwa chakapwanyika. Kushandiswa kwechinhu chinosimbisa kunewo mhedzisiro yakati pakuderedza kupwanyika kwechigadzirwa uye kuwedzera tembiricha yekushanduka kwekupisa uye simba rekupisa rakaderera.
Mukugadzira zvigadzirwa zveFRP, kusarudzwa kwezvinhu zvinosimbisa kunofanirwa kufunga zvizere nezvemaitiro ekuumba chigadzirwa, nekuti mhando, nzira yekuisa uye zviri mukati mezvinhu zvinosimbisa zvine simba guru pakushanda kwezvigadzirwa zveFRP, uye zvinonyanya kusarudza simba remuchina uye elastic modulus yezvigadzirwa zveFRP. Kushanda kwezvigadzirwa zvakapwanyika uchishandisa zvinhu zvakasiyana zvinosimbisa kwakasiyanawo.
Pamusoro pezvo, kunyangwe zvichizadzisa zvinodiwa pakushanda kwechigadzirwa panguva yekuumba, mutengo unofanirwawo kufungwa nezvawo, uye zvinhu zvinosimbisa zvakachipa zvinofanira kusarudzwa zvakanyanya sezvinobvira. Kazhinji, kutenderera kwetambo dzegirazi dzisina kusarudzwa kwakaderera pamutengo pane machira efiber; mutengo wemachira egirazi efaibhayakaderera pane yejira, uye kunyungudika kwayo kwakanaka. , asi simba rayo rakaderera; alkali fiber yakachipa pane alkali-free fiber, asi nekuwedzera kwehuwandu hwealkali, kunyungudika kwayo kwealkali, kunyungudika kwayo, uye hunhu hwemagetsi zvinoderera.
Mhando dzezvinhu zvinosimbisa zvinoshandiswa zvakanyanya ndedzinotevera
1. Kufamba-famba kwegirazi risina kumonyoroka
Uchishandisa mumiririri wekusimbisa saizi, usina kumonyororwagirazi fiber rovinginogona kukamurwa kuita mhando nhatu: sirika isina kubikwa yakapfekwa, kufamba-famba isina kutwasuka zvakananga uye kufamba-famba isina kutwasuka yakawanda.
Nekuda kwekusawirirana kwematambo akasungirirwa, zviri nyore kudonha, izvo zvinoita kuti pave nechitenderedzo chakasununguka pamucheto wekushandisa kwemuchina we pultrusion, izvo zvinokanganisa kufambira mberi kwakanaka kwekushanda.
Kufamba-famba kusina kumonyoroka zvakananga kune hunhu hwekuungana kwakanaka, kupinda kweresin nekukurumidza, uye hunhu hwakanaka hwemakanika ezvigadzirwa, saka mazhinji ekufamba-famba kusina kumonyoroka zvakananga anowanzo shandiswa pari zvino.
Matambo ekurunga anobatsira kuvandudza simba rezvinhu zvakachinjika, zvakaita sematambo akakwenenzverwa uye matambo emhepo. Matambo ekurunga ane simba guru rematambo marefu anoramba aripo uye matambo mapfupi akakura. Chinhu chine simba rekupisa kwakanyanya, kupisa kwakaderera, ngura, kugona kwakanyanya uye kushanda zvakanaka kwekusefa. Mamwe matambo anokurunga kuita monofilament state, saka anogonawo kuvandudza kunaka kwezvigadzirwa zvakarungwa. Parizvino, matambo ekurunga agara achishandiswa zvakanyanya kumba nekune dzimwe nyika, sewarp neweft yarns dzemachira ekushongedza kana eindasitiri. Inogona kushandiswa kugadzira zvinhu zvinokweshana, zvinodzivirira, zvinodzivirira kana zvinovhara.
Zvinodiwa pakushanda kwegirazi risina kumonyororwa fiber rotavings ye pultrusion:
(1) Hapana chiitiko chekurembera pamusoro;
(2) Kusimba kwefiber kwakafanana;
(3) Kuunganidza zvakanaka;
(4) Kusapfeka zvakanaka;
(5) Misoro mishoma yakatyoka, uye hazvisi nyore kuichinja-chinja;
(6) Kunyorova zvakanaka uye kupinza resin nekukurumidza;
(7) Simba guru uye kuomarara.

2. Mati yegirazi yefaibha
Kuti zvigadzirwa zveFRP zvakapwanyika zvive nesimba rakakwana rekuchinjika, zvinhu zvinosimbisa zvakaita semachira etambo akachekwa, machira etambo anochinjika, machira akabatanidzwa, uye jira reshinda risina kumonereka zvinofanira kushandiswa. Machira etambo anochinjika ndeimwe yezvinhu zvinonyanya kushandiswa pari zvino zvekusimbisa tambo yegirazi. Kuti zvivandudze chitarisiko chezvigadzirwa,meti yepamusorodzimwe nguva inoshandiswa.
Mati yetambo inoenderera mberi inoumbwa nezvidimbu zvakasiyana-siyana zvemagirazi anoenderera mberi akaiswa mudenderedzwa zvisina tsarukano, uye mashinda acho akabatanidzwa nezvinonamira. Chinonamira pamusoro isimbi yakatetepa yakaita sepepa inoumbwa nekuiswa tambo dzakachekwa dzisina tsarukano uye dzakafanana dzakareba dzakaganhurirwa uye dzakasungirirwa nechinamira. Huremu hwefiber huri pakati pe5% kusvika 15%, uye ukobvu huri pakati pe0.3 kusvika 0.4 mm. Inogona kuita kuti pamusoro pechigadzirwa pave pakanaka uye pakanaka, uye inovandudza kuramba kwechigadzirwa kukwegura.
Hunhu hwegirazi fiber mat ndehwekuti: kufukidzwa kwakanaka, kuri nyore kuzara ne resin, glue yakawanda
Zvinodiwa pakuita pultrusion process yegirazi fiber mat:
(1) Ine simba guru remakanika
(2) Pamachira etambo akachekwa nemakemikari, chinobatanidza chinofanira kunge chisingabatanidzwi nemakemikari uye kupisa panguva yekunyikwa nekugadzira kuti chive nechokwadi chekuti chakasimba zvakakwana panguva yekugadzira;
(3) Kunyorova zvakanaka;
(4) Kusanyanya kusimba uye misoro yakatyoka mishoma.
Meti yakasonerwa negirazi refiberglass
Mat yegirazi ine fiber yakagadzirwa negirazi
3. Meti yepamusoro pe polyester fiber
Polyester fiber surface felt imhando itsva yezvinhu zvinosimbisa fiber muindasitiri ye pultrusion. Kune chigadzirwa chinonzi Nexus muUnited States, chinoshandiswa zvakanyanya muzvigadzirwa zve pultruded kutsivamameti egirazi efaibha pamusoro. Ine simba rakanaka uye inodhura zvishoma. Yave ichishandiswa zvinobudirira kwemakore anopfuura gumi.
Zvakanakira kushandisa mat yepolyester fiber tissue:
(1) Inogona kuvandudza kuramba kukanganiswa, kuramba ngura uye kuramba kukwegura kwezvigadzirwa mumhepo;
(2) Inogona kuvandudza mamiriro epamusoro pechigadzirwa uye kuita kuti pamusoro pechigadzirwa pave panyoro;
(3) Kushandiswa uye hunhu hwekudhonza kwepolyester fiber surface felt zviri nani kupfuura C glass surface felt, uye hazvisi nyore kupwanya magumo panguva yekuputika, zvichideredza tsaona dzekupaka;
(4) Kumhanya kwe pultrusion kunogona kuwedzerwa;
(5) Inogona kuderedza kupera kweforoma uye kuvandudza hupenyu hweforoma
4. Tepi yejira regirazi refaibha
Mune zvimwe zvigadzirwa zvakakosha zvakapwanyika, kuti zvizadzise zvinodiwa pakushanda kwakakosha, jira regirazi rine upamhi hwakatarwa uye ukobvu husingasviki 0.2mm rinoshandiswa, uye simba rayo rekudhonza uye simba rakachinjika zvakanaka kwazvo.
5. Kushandiswa kwemachira ane mativi maviri uye machira ane mativi matatu
Hunhu hwezvinhu zvakagadzirwa ne pultruded composite hwakasiyana, uye kushandiswa kwekurukwa kwemativi maviri kunobatsira zvikuru kusimba nekuomarara kwezvigadzirwa zvakagadzirwa ne pultruded.
Matayi ejira iri rakarukwa akarukwa haana kubatana, asi akabatana nechimwe chinhu chakarukwa, saka akasiyana zvachose nejira regirazi rekare. Matayi ari kurutivi rumwe nerumwe ari muchimiro che collimated uye haaite chero kukotama, uye nokudaro simba nekuoma kwechigadzirwa chakaputsika, zvakakwirira zvikuru kupfuura zvemusanganiswa wakagadzirwa ne continuous felt.
Parizvino, tekinoroji yekuruka mativi matatu yave iri munda wekuvandudza tekinoroji inokwezva uye inoshanda muindasitiri yezvinhu zvakasanganiswa. Zvichienderana nezvinodiwa nemutoro, fiber yekusimbisa inorukwa zvakananga muchimiro chine chimiro chemativi matatu, uye chimiro chakafanana nechechigadzirwa chakasanganiswa chainoumba. Jira remativi matatu rinoshandiswa mukuita kwepultrusion kukunda interlaminar shear yezvigadzirwa zvechinyakare zvekusimbisa fiber pultrusion. Ine zvikanganiso zvekusimba kushoma kwekucheka uye nyore kuchenesa, uye mashandiro ayo einterlayer akanaka kwazvo.
