Modificação das propriedades das fibras de curauá por acetilação Modification of the properties of curauá fibers by acetylation

Revista Brasileira de Engenharia Agrícola e Ambiental, 2011
Nos compósitos cimentíceos as fibras vegetais podem sofrer vários graus de degradação quando expostas ao ambiente alcalino. O meio alcalino degrada os componentes macromoleculares das fibras, principalmente pela solubilização da lignina e a desfibrilação

Abaca fiber as an efficient reinforcement for high mechanical performance in metakaolin‐based geopolymers

International Journal of Applied Ceramic Technology, Volume 21, Issue 2, Page 1154-1169, March/April 2024.
Abstract This study introduces an innovative method for efficiently integrating abaca fibers into a potassium‐based geopolymer (KGP) material. Geopolymers often suffer from brittleness, and composite designs have been explored as a solution to enhance their strength and ductility.
