Sisal chemically modified with lignins: Correlation between fibers and phenolic composites properties
(ELSEVIER SCI LTD, 2008)
Sisal fibers have been chemically modified by reaction with lignins, extracted from sugarcane bagasse and Pinus-type wood and then hydroxymethylated, to increase adhesion in resol-type phenolic thermoset matrices. Inverse ...
Biobased composites from tannin-phenolic polymers reinforced with coir fibers
(ELSEVIER SCIENCE BV, 2010)
Tannin-phenolic polymers prepared using tannin, a macromolecule obtained from natural sources, were used in the preparation of composites reinforced with coir fibers. The composites based on tannin-phenolic polymers (50% ...
