E tusa ai ma le lipoti lata mai, o le isi augatupulaga o mea tuʻufaʻatasia e mafai ona mataʻituina o latou lava tulaga faʻalesoifua maloloina, ma avea ma masani.
O mea fa'apipi'i alava kaponi e mama ma malosi ma o mea taua fa'avae mo ta'avale, va'alele ma isi auala fela'uaiga. E aofia ai polymer substrates, e pei o resins epoxy, o loʻo faʻapipiʻiina i alava carbon faʻamalosia. Ona o le eseese o mea faʻainisinia o mea e lua, o alava o le a paʻu ese mai le meaʻai i lalo o le mamafa tele poʻo le vaivai. O lona uiga o le fa'aleagaina o le fausaga fa'apipi'i alava kaponi e ono natia i lalo o le fogā'ele'ele ma e le mafai ona iloa e le mata le lava, lea e ono i'u ai i fa'alavelave mata'utia.
"E ala i le malamalama i totonu o mea faʻapipiʻi, e mafai ona e faʻamasinoina lelei lo latou soifua maloloina ma iloa pe i ai ni mea faʻaleagaina e manaʻomia ona toe faʻaleleia," Ridge Chris Bowland, o se tagata suʻesuʻe i le
Oak Ridge National Laboratory i le US Department of Energy (Oak National Laboratory) Wigner. Talu ai nei, na faia ai e Amit Naskar, o le ulu o le carbon and composites team i Bowland ma ORNL, se auala taʻavale e afifi ai alava carbon conductive i semiconductor silicon carbide nanoparticles. O nanomaterials o loʻo faʻapipiʻiina i mea tuʻufaʻatasia e sili atu le malosi nai lo isi fiber-faʻamalosia composites ma maua se malosi fou e mataʻituina ai alava. le polymer, o le alava e fausia ai le eletise, ma o le tele o mea faʻapipiʻi e faʻatautaia le eletise Semiconductor nanoparticles e mafai ona faʻaumatia lenei eletise eletise i lalo o le gaioiga a le malosi i fafo, faʻaopoopoina galuega faʻainisinia ma eletise i mea faʻapipiʻi, o le a faʻaumatia le fesoʻotaʻiga o filo faʻapipiʻi ma le faʻalavelave i le mea o le a suia le faʻailoga komepiuta a le vaalele e faailoa ai o le apaau o loo i lalo o le mamafa tele ma fautuaina se suega O le taʻavale solo faʻataʻitaʻiga o ORNL faʻamaonia i le mataupu faavae e mafai e le auala e maua ai le isi augatupulaga o filo faʻapipiʻi faʻapipiʻi i luga o le tele o mea faʻapipiʻi faʻapipiʻi i totonu o nanoparticles, na faʻapipiʻi ai e le au suʻesuʻe ni taʻavale carbon fiber maualuga i luga o taʻavale, ma o loʻo faʻafefeteina e le uila alava i le epoxy resins, lea o loʻo i ai nanoparticles avanoa i luga o le maketi, o lona lautele e tusa ma le lautele o le siama (45-65 nm).
Ona fa'amamago lea o alava i totonu o le ogaumu e fa'amautu ai le ufiufi. Ina ia faʻataʻitaʻiina le malosi o filo o loʻo faʻapipiʻiina i nanoparticles faʻapipiʻi i le polymer substrate, na faia ai e le au suʻesuʻe ni faʻamau faʻamalosi faʻamalosia fiber, lea na faʻatulagaina i le One Direction. Na faia e le Bowl ma se suʻega faʻamalosi lea na faʻamautu ai pito o le cantilever, aʻo suʻesuʻeina e le masini mea faʻainisinia e faʻaogaina i le ogatotonu o le faʻamalo seia oʻo ina faʻaogaina le faʻamalo. Ina ia mafai ona suʻesuʻeina le gafatia o le faʻaogaina o mea tuʻufaʻatasia, na ia faʻapipiʻi eletise i itu uma e lua o le faʻalava. I totonu o se masini e ta'ua o le "Dynamic mechanical analyzer," na ia tipiina le tasi pito e taofi ai le fa'alava. O le masini e fa'amalosi i le isi pito e lolo'u ai le la'au fa'agata a'o mata'ituina e Bowl ma le suiga o le tete'e. O le ORNL, o se tagata suʻesuʻe postdoctoral Ngoc Nguyen, na faia ni suʻega faʻaopoopo i le Fourier Transform Infrared spectrometer e suʻesuʻe ai vailaʻau faʻapipiʻi ma faʻaleleia atili le malamalama i le faʻaleleia atili o le malosi faʻainisinia ua matauina. Na suʻesuʻe foi e le au suʻesuʻe le gafatia o le malosi faʻaleagaina o mea faʻapipiʻi e faia i le tele o nanoparticles (fuaina i le vibration damping behavior), lea e faafaigofie ai le tali atu o mea faʻavae i faʻateʻia, vibration ma isi faʻafitauli ma faʻafitauli. I faʻatonuga taʻitasi, e mafai e nanoparticles ona faʻaleleia le faʻaogaina o le malosi (mai le 65% i le 257% i tikeri eseese). Bowland ma Naskar ua talosaga mo se pateni faagasologa mo le gaosia o le tagata lava ia lagona carbon fibre composite.
"O paʻu faʻafefeteina e maua ai se auala fou e faʻaogaina ai mea fou nanomaterials o loʻo faʻalauteleina. "O le tala lea a Bowlland. O le suʻesuʻega na lagolagoina e suʻesuʻega ma atinaʻe poloketi faʻatonuina e le ORNL Laboratory, lomia i le tusi talaaga ACS Applied Materials and Interfaces (Applied Materials & Interfaces) a le American Chemical Society.
