Resumo: The number of published scientific papers about natural fibers as a filler to produce composite filaments for additive manufacturing (AM) has increased in recent years. The aim of this thesis is to develop and characterize rice husk filled PLA composites obtained by AM. Thus, rice husks (RH) were blended with PLA (IngeoTM Biopolymer 4043D) to produce natural fiber filled polymer (NFFP) filaments for AM with fiber amounts between 5 and 20 wt.%. Raw materials, filaments produced and printed parts were characterized. The results showed that the filaments with a fiber content above 15 wt.% were not printable. Adding RH fibers to PLA negatively affected the mechanical strength, water absorption and densities on printed parts, mainly due to high variation in the filament diameter.

O objetivo desta tese foi desenvolver e caracterizar compósitos de PLA e casca de arroz obtidos por FA. Assim, cascas de arroz (CA) foram misturadas com PLA (IngeoTM Biopolymer 4043D) para produzir filamentos de polímero preenchido com fibra natural (PPFN) para FA, com quantidades de fibra a variar entre 5 e 20% em peso. Matérias-primas, filamentos produzidos e peças impressas foram caracterizados. Os resultados mostraram que os filamentos com um conteúdo em fibra superior a 15% em peso não eram imprimíveis. Além disso, adicionar fibras de CA ao PLA afetou negativamente a resistência mecânica, absorção de água e densidades das peças impressas, principalmente devido à variação no diâmetro do filamento.Pina, CélioMarques, Ana ClaraRepositório ComumPereira, Daniel Alexandre Feliciano2023-01-04T10:48:24Z2022-122022-12-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10400.26/42950TID:202911241enginfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-11-21T09:57:21Zoai:comum.rcaap.pt:10400.26/42950Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T23:12:44.200023Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
