Izinto zokuqinisa i-skeleton exhasayo yeFRP imveliso , eyona nto imisela iimpawu zomatshini wemveliso ye-pultruded. Ukusetyenziswa kwezinto zokuqinisa kwakhona kunempembelelo ethile ekunciphiseni ukucutheka kwemveliso kunye nokwandisa ubushushu be-thermal deformation kunye namandla aphantsi kwempembelelo yokushisa.
Kuyilo lweemveliso ze-FRP, ukukhethwa kwezinto zokuqinisa kufuneka kuthathelwe ingqalelo ngokupheleleyo inkqubo yokubumba imveliso, kuba uhlobo, indlela yokubeka kunye nomxholo wezinto eziqinisayo zinempembelelo enkulu ekusebenzeni kweemveliso ze-FRP, kwaye ngokusisiseko zinquma umatshini. amandla kunye ne-elastic modulus yeemveliso ze-FRP. Ukusebenza kweemveliso ze-pultruded usebenzisa izinto ezahlukeneyo zokuqinisa nazo zihluke.
Ukongeza, ngelixa uhlangabezana neemfuno zokusebenza kwemveliso yenkqubo yokubumba, iindleko kufuneka ziqwalaselwe, kwaye izixhobo zokuqinisa eziphantsi kufuneka zikhethwe kangangoko kunokwenzeka. Ngokubanzi, ukuzulazula okungajikwanga kwemisonto yefiber yeglasi kunexabiso eliphantsi kunamalaphu efayibha; ixabiso lokuziva liphantsi kunelaphu, kwaye ukunganyanzeki kulungile. ke amandla aphantsi; i-alkali fiber inexabiso eliphantsi kune-alkali-free fiber, kodwa ngokunyuka komxholo we-alkali, ukuxhathisa kwayo kwe-alkali, ukuxhathisa ukubola kunye neempawu zombane ziya kuncipha.
Iindidi zezixhobo zokuqinisa ezisetyenziswa ngokuqhelekileyo zezi zilandelayo:
1. I-Glass Fiber Roving engajijekanga
Usebenzisa i-agent yokulinganisa eyomeleziweyo, i-glass fiber roving engajikwanga inokwahlulwa ibe ziindidi ezintathu: umsonto owenziwe ngeplied, ukuzulazula okuthe ngqo okungajikwanga kunye nokuzulazula okungajikwanga.
Ngenxa yoxinzelelo olungalinganiyo lwemicu yeplied, kulula ukuntywila, okwenza i-loop evulekileyo ekupheleni kokutya kwezixhobo ze-pultrusion, echaphazela inkqubela phambili yokusebenza.
Iirovings ezithe ngqo ezingajikwanga zineempawu zokudityaniswa kakuhle, ukungena kwe-resin ngokukhawuleza, kunye neempawu ezigqwesileyo zomatshini weemveliso, ngoko uninzi lwazo lutyekele ekusebenziseni ii-rovings ezithe ngqo ngoku.
I-bulked roving iluncedo ekuphuculeni ukomelela okunqamlezayo kweemveliso, ezinje nge-crimped roving kunye ne-air-textured roving. I-Bulk roving inamandla aphezulu eentsinga ezinde eziqhubekayo kunye nobuninzi beentsinga ezimfutshane. Yimpahla enokumelana nobushushu obuphezulu, i-thermal conductivity ephantsi, ukumelana nokugqwala, umthamo ophezulu kunye nokusebenza kakuhle kokucoca. Ezinye iintsinga zixutywe kwimo ye-monofilament, ngoko inokuphucula umgangatho wemveliso ye-pultruded. Okwangoku, i-rovings bulked isetyenziswe ngokubanzi ekhaya nakwamanye amazwe, njengeentambo ezirp kunye ne-weft zokuhombisa okanye kwimizi-mveliso elukiweyo. Ingasetyenziselwa ukuvelisa ukukhuhlana, ukugquma, ukukhuselwa okanye izinto zokutywina.
Iimfuno zokusebenza zeglasi engajikwanga yefiber roving for pultrusion:
(1) Akukho mcimbi we-drape
(2) Uxinzelelo lwefayibha efanayo
(3) Ukudibanisa kakuhle
(4) Ukumelana nokunxiba kakuhle
(5) Zophukile Iintloko ezimbalwa, akukho lula ukuziphaphamisa
(6) Ukumanzisa okulungileyo kunye nokukhawuleza kwe-resin impregnation
(7) Amandla aphezulu kunye nokuqina.
2. I-Fiberglass Mat
Ukuze wenze iimveliso ze-FRP ezixutyiweyo zibe namandla okwaneleyo anqamlezayo, kuyafuneka ukuba kusetyenziswe izinto zokuqinisa ezifana ne-strand mat enqunqiweyo, i-continuous strand mat, i-mat edibeneyo, kunye nelaphu elijikelezayo. I-continuous strand mat yenye yezona zinto zixhaphakileyo zisetyenziswa kwigilasi fiber transverse imathiriyeli yokuqinisa okwangoku. Ukuze kuphuculwe imbonakalo yeemveliso, i-surface mat isetyenziswa ngamanye amaxesha.
I-strand mat eqhubekayo yenziwe ngamacandelo amaninzi eentsinga zeglasi eziqhubekayo ezibekwe ngokungaqhelekanga kwisangqa, kwaye iifayili ziboshwe nge-adhesive. I-surface mat yi-tissue encinci efana nephepha eyenziwe ngokulandelelana kunye nokubeka ngokulinganayo imicu enqunqiweyo yobude obusisigxina kwaye iboshwe nge-adhesive. Umxholo wefiber ngu-5% ukuya kwi-15%, kwaye ubukhulu be-0.3 ukuya kwi-0.4 mm. Inokwenza ubuso bemveliso bugudiswe kwaye bubuhle, kwaye buphucule ukumelana nokuguga kwemveliso.
Iimpawu zeglasi yefiber mat zezi: ukugqunywa kakuhle, kulula ukuhluthwa yiresin, kunye nomxholo weglue ophezulu.
Iimfuno zenkqubo ye-pultrusion ye-glass fiber mat:
(1) Inamandla amakhulu omatshini
(2) Kwiimethi ezidityanisiweyo zemichiza ezidityanisiweyo, isibophelelo kufuneka singanyangeki kwiziphumo zekhemikhali kunye ne-thermal ngexesha lokudipha kunye nokulungiswa kwangaphambili ukuze kuqinisekiswe amandla awoneleyo ngexesha lenkqubo yokwenza.
(3) Ukumanzisa okulungileyo
(4) I-fluff encinci kwaye iyancipha idibeneyo / iziphelo ezimbalwa
3.IpolyesterFiberSubusoIzicubu
I-polyester fiber surface tissue luhlobo olutsha lwezinto zokuqinisa ifayibha kwishishini le-pultrusion. Kukho imveliso ebizwa ngokuba yi-Nexus e-United States, esetyenziswa kakhulu kwiimveliso ze-pultruded ukuthatha indawo ye-glass fiber surface mats/tissue/fleece. Inesiphumo esihle kunye neendleko eziphantsi. Isetyenziswe ngempumelelo iminyaka engaphezu kwe-10.
Iingenelo zokusebenzisa i-polyester fiber surface tissue:
(1) Inokuphucula ukuxhathisa impembelelo, ukuxhathisa ukubola kunye nokumelana nokuguga kwe-atmospheric yemveliso
(2) Iyakwazi ukuphucula umgangatho wemveliso kwaye yenza ubuso bemveliso bube lula
(3) I-polyester fiber surface tissue, ukusebenza okunamathelayo kunye nokusebenza kwe-tensile kungcono kakhulu kune-C glass surface tissue / mat, kwaye akulula ukuphula iziphelo ngexesha lenkqubo ye-pultrusion, ukunciphisa iingozi zokupaka.
(4) Inokuphucula isantya se-pultrusion
(5) Inokunciphisa ukunxiba kwesikhunta kunye nokuphucula ubomi benkonzo yokubumba.
4. IglasiCloth/Tinkawu
Kwezinye iimveliso ezikhethekileyo ze-pultruded, ukuze kuhlangatyezwane neemfuno ezikhethekileyo zokusebenza, ilaphu leglasi elinobubanzi obumiselweyo kunye nobukhulu obungaphantsi kwe-0.2mm liyasetyenziswa, kwaye amandla alo okuqina kunye namandla anqamlezayo alungile kakhulu.
5. Ukusetyenziswa kweTi-wo-dimensionalFiidyasi& Ntathu-umdaFiidyasi
Iimpawu zomatshini ezinqamlezileyo zeemveliso ezixutyiweyo ezixutyiweyo zimbi. Ukusetyenziswa kweendlela ezimbini zokubopha ngokufanelekileyo kuphucula amandla kunye nokuqina kweemveliso ze-pultruded.
Iintsinga ze-warp kunye ne-weft yeli laphu elilukiweyo ayidityaniswanga enye kwenye, kodwa idityaniswe nenye into elukiweyo, ngoko ke yahluke ngokupheleleyo kwilaphu leglasi yemveli. Iifiber kwicala ngalinye zikwimeko edibeneyo kwaye azenzi Nakuphi na ukugoba, kwaye ngoko ke amandla kunye nokuqina kwemveliso ye-pultruded, iphezulu kakhulu kunokuba i-composite eyenziwe ngokuziva ngokuqhubekayo. Okwangoku, itekhnoloji yendlela-ntathu yokuluka iye yaba yeyona ndawo inomtsalane kwaye isebenzayo yophuhliso lwetekhnoloji kushishino lwemathiriyeli edibeneyo. Ngokweemfuno zomthwalo, i-fiber yokuqinisa ilukwe ngokuthe ngqo kwisakhiwo esinesakhiwo esine-dimensional-dimensional, kwaye imilo iyafana nokumila kwemveliso edibeneyo eyenza. Ilaphu elineendlela ezintathu ezisetyenziswa kwinkqubo ye-pultrusion inokoyisa i-interlaminar shear yeemveliso zemveli zokuqinisa i-fiber pultrusion. Inobugwenxa bamandla okucheba asezantsi kunye ne-delamination elula, kwaye ukusebenza kwayo kwe-interlayer ilungile. (Umthombo: iFiberglass Composites / Composites Community)
