Epoxy composites containing 130-nm spherical silica nanoparticles were prepared at a fixed volume fraction (phi = 0.5 %). To prevent agglomeration the silica fillers were initially pre-treated with diglycidyl ether of bisphenol A. Due to the low content of silica fillers their inclusion in the matrix was confirmed by the increased roughness of the fracture surface compared to the smooth surface of the neat epoxy. Fourier-transform infrared spectroscopy (FTIR) was employed to confirm the changes in the functional groups on the surface of the unmodified and modified silica</dc:description><dc:description xml:lang="sl">V tem članku smo se osredinili na pripravo epoksidne smole Epikote 828LVEL z dodatkom silicijevega dioksida. Pripravili smo epoksikompozite, ki so vsebovali sferične nanodelce silicijevega dioksida velikosti 130 nm z volumenskim deležem fi = 0,5 %. Da bi preprečili aglomeracijo, smo silicijev dioksid predhodno modificirali z diglicidil etrom bisfenola A. Zaradi majhne vsebnosti polnila smo njihovo vključitev v osnovo potrdili s povečano hrapavostjo na mestu preloma v primerjavi z gladko površino čistega epoksikompozita. Z infrardečo spektroskopijo s Fourierjevo transformacijo (FTIR) smo potrdili spremembe funkcionalnih skupin na površini nemodificiranega in modificiranega silicijevega dioksida</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-JOOZWTEX"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-JOOZWTEX" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-JOOZWTEX/df4637c4-6e26-4f8e-84ff-57099e5bd603/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Inštitut za kovinske materiale in tehnologije</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-JOOZWTEX/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-JOOZWTEX" /></ore:Aggregation></rdf:RDF>
