Lub zog ntawm cov khoom siv ntawm cov khoom siv sib xyaw yog tus thawj coj los ntawm cov fibers. Qhov no txhais tau tias thaum cob qhia thiab cov fibers tau sib xyaw ua ke, lawv cov peev xwm zoo heev rau cov neeg ntawm ib tus neeg. Cov ntaub ntawv xeem qhia tias cov khoom siv siv hluav taws xob fiber ntau yog cov khoom sib xyaw uas muaj feem ntau ntawm lub nra. Yog li ntawd, cov ntaub npuag yog qhov tseem ceeb thaum tsim qauv sib xyaw.
Pib cov txheej txheem los ntawm kev txiav txim siab hom cuab tam uas xav tau hauv koj qhov project. Raug cov tuam ntxhab tuaj yeem xaiv los ntawm peb cov ntaub ntawv lub zog tshwj xeeb: iav fiber ntau, carbon fiber ntau, carbon fiber ntau thiab kev muag khoom muaj roj av). Iav Fibers zoo li yog cov carbon fibers muab siab tawv me ntsis thiab kevat® ua hauj lwm siab tsis kam. Nco ntsoov tias cov ntaub npuag tuaj yeem ua ke hauv laminates los ua cov hybrid stacks nrog cov txiaj ntsig ntawm ntau tshaj ib cov khoom.
Thaum koj tau txiav txim siab ntawm cov ntaub ntawv sau, xaiv qhov hnyav thiab weave cov style uas haum koj txoj haujlwm xav tau. Lub teeb ci rau ooj ntawm cov ntaub, qhov yooj yim nws yog kom drape hla cov chaw siab. Lub teeb yuag kuj tseem siv cov resin tsawg dua, yog li lub laminate zuag qhia tag nrho tseem sib dua. Raws li cov ntaub kom hnyav dua, lawv tsis tshua yoog. Qhov hnyav nruab nrab khaws cov khoom txaus los npog feem ntau cov contours, thiab lawv pab txhawb nqa lub zog ntau. Lawv muaj kev lag luam heev thiab tsim cov khoom siv muaj zog thiab lub ntsej muag rau kev kho tsheb, cov ntawv thov marine thiab kev lag luam. Braided Rovings yog cov kev txhawb zog hnyav feem ntau siv hauv nkoj thiab pwm ua.
Txoj kev uas ib daim ntaub yog Woven yog suav tias yog nws tus qauv lossis style. Xaiv los ntawm peb cov khaub ncaws uas sib txawv: Plain, Satin thiab twill. Cov khaub ncaws dawb yog cov pheej yig thiab tsis tshua yoog raws li, tab sis lawv tuav ua ke zoo thaum txiav. Nquag / nqis hla cov xov txo lub zog ntawm lub tiaj weave ntawm lub tiaj weave, txawm hais tias lawv tseem txaus siab thov.
Satin thiab twill hiab yog softer thiab muaj zog dua li weave tsis. Hauv Satin Weaving, ib qho weft xov ntab tshaj li peb mus rau xya lwm yam warp xov thiab yog tom qab ntawd xaws nyob rau lwm qhov. Nyob rau hauv cov xoob dej weave hom, cov xov tau sau ntev dua, tswj hwm qhov ua kom lub siab tawv ntawm cov fiber. Ib qho twill weave muaj kev cuam tshuam ntawm satin thiab cov qauv tiaj, nrog cov herringirball ntau zaus.
Tech Tip: Txhawm rau ntxiv yooj yim rau cov ntaub, txiav nws los ntawm cov yob ntawm 45-degree kaum. Thaum txiav txoj kev no, txawm tias cov ntxhib cov ntaub tau zoo dua cov silhouette.
Fiberglass txhawb ntxiv
Fiberglass yog lub hauv paus ntawm kev sib xyaw kev lag luam. Nws tau siv nyob rau hauv ntau daim ntawv thov sib xyaw txij li xyoo 1950 thiab nws lub cev lub zog tau to taub zoo. Cov fiberglass yog lub teeb yuag, muaj cov tensile me ntsis thiab lub zog compressive, tuaj yeem tiv thaiv kev puas tsuaj thiab ua kom tau yooj yim.
Cov fiberglass yog qhov feem ntau dav siv ntawm txhua cov ntaub ntawv sib xyaw. Qhov no yog feem ntau yog vim nws tus nqi qis thiab muaj zog nruab nrab lub cev. Fiberglass yog qhov zoo rau txhua hnub haujlwm thiab cov seem uas tsis tas yuav muaj fiber ntau ntaub ntxiv lub zog thiab kav ntev.
Txhawm rau kom ua tiav lub zog ntawm cov khoom ntawm cov fiberglass, nws tuaj yeem siv nrog epoxy thiab tuaj yeem kho tau siv cov qauv laminques. Nws yog qhov zoo tagnrho rau kev thov hauv automotive, tsim kev tsim kho, tshuaj kho kom zoo, tshuaj lom neeg thiab feem ntau siv hauv cov khoom ntaus pob ncaws pob.
Kevlar® Qhov Cuab Lub Zog
Kevlas Kev Tsim Kho Hluav Taws Xob kom tau txais kev lag luam fiber ntau ntxiv plastics (FRP) kev lag luam. Composite Qib Kevlar® yog lub teeb yuag, muaj qhov zoo tshaj plaws lub zog tensile lub zog, thiab yog cuam tshuam kom muaj kev cuam tshuam zoo heev thiab puas resistant. Cov ntawv thov uas muaj xws li lub teeb HULLS xws li Kayaks thiab canes, aircraft hnab looj tes thiab cov hnab looj tes siab, cov hnab looj tes siab, lub cev armor, thiab ntau dua. Kevlar® yog siv nrog epoxy lossis vinyl ester resins.
Carbon Fiber txhawb
Carbon fiber muaj ntau tshaj li 90% carbon thiab muaj qhov kawg qhov kawg tensile lub zog hauv kev lag luam frp. Qhov tseeb, nws tseem muaj qhov siab tshaj plaws compressive thiab flexural zog hauv kev lag luam. Tom qab kev ua tiav, cov fibers sib xyaw ua ke los ua daim carbon fiber kev txhawb nqa xws li cov ntaub, hmoov av, thiab lwm yam. Carbon cov fiber ntau txhawb nqa lub zog thiab txhav, thiab nws feem ntau kim dua li lwm cov kev txhawb nqa fiber ntau dua li lwm cov kev txhawb nqa fiber ntau dua li lwm cov kev txhawb nqa.
Txhawm rau ua kom pom tau lub zog ntawm cov fiber carbon fiber, nws yuav tsum tau siv nrog epoxy thiab tuaj yeem kho tau siv cov qauv laminques. Nws yog qhov zoo tagnrho rau kev siv hauv kev kho tsheb, cov tubrog nkoj thiab ib lub aerospace, thiab feem ntau siv hauv cov khoom ntaus pob ncaws pob.
