The material dates to 1893, when spun glass fibers were made into fabric by Edward D. Libbey and exhibited at the Columbian Exhibition in Chicago. Owen-Corning developed several processes for making fine, continuous glass fibers in the 1930s, which were sold under the trademark of ‘Fiberglas.’ Over time, the term 'fiberglass' became generally used for all glass fiber products.</skos:scopeNote><skos:inScheme rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en"/><skos:related rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31373851"/><skos:broader rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31344444"/><skos:narrower rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31412005"/><skos:narrower rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31412007"/><skos:exactMatch> <skos:Concept rdf:about="http://AATesaurus.cultura.gencat.cat/aat/getty_ca/index.php?tema=9848061"> <skos:prefLabel xml:lang="ca">fibra de vidre</skos:prefLabel> </skos:Concept></skos:exactMatch><skos:exactMatch> <skos:Concept rdf:about="http://AATesaurus.cultura.gencat.cat/aat/getty_es/index.php?tema=14085734"> <skos:prefLabel xml:lang="es">fibra de vidrio</skos:prefLabel> </skos:Concept></skos:exactMatch>  <dct:created>2026-03-30 20:41:08</dct:created>  </skos:Concept></rdf:RDF>
