Optimal Tensile Properties of Biocomposites Made of Treated Amazonian Curauá Fibres Using Taguchi Method

Materials Research, 2021
Natural fibres have many advantages over synthetic ones, making them attractive for reinforcing polymer materials. This work evaluates the use of an Amazonian plant, namely Curauá (Ananas erectifolius), as a reinforcement phase of biocomposites ...

Stone Matrix Asphalt (SMA) with Construction Waste and Curauá Fiber (Ananas erectifolius)

Research, Society and Development, 2020
The SMA mixtures are characterized by a high void ratio, which favors binder draindown. In order to avoid this effect, fibers are added to the mixture, which in this case came from Curauá da Amazônia (Ananas erectifolius). The final composition studied resulted in 75% coarse aggregate, 15% fine aggregate, 10% filler, 0.3% of the Curauá fiber residue ...

The bracteatus pineapple genome and domestication of clonally propagated crops [PDF]

, 2019
Domestication of clonally propagated crops such as pineapple from South America was hypothesized to be a 'one-step operation'. We sequenced the genome of Ananas comosus var.

Tricin‐lignins: occurrence and quantitation of tricin in relation to phylogeny

The Plant Journal, Volume 88, Issue 6, Page 1046-1057, December 2016., 2016
Summary Tricin [5,7‐dihydroxy‐2‐(4‐hydroxy‐3,5‐dimethoxyphenyl)‐4H‐chromen‐4‐one], a flavone, was recently established as an authentic monomer in grass lignification that likely functions as a nucleation site. It is linked onto lignin as an aryl alkyl ether by radical coupling with monolignols or their acylated analogs.

Propriedades físicas e mecânicas de compósitos de cimento reforçados com fibra de curauá (Ananas erectifolius)

Engenharia Civil UM, 2022
O objetivo deste estudo é a caracterização de compósitos cimentícios com reforço de fibras longas de curauá. Estes compósitos são constituídos de matriz cimentícia composta por cimento CP V-ARI, areia, água e superplastificante. A substituição de materiais como o cimento por reforços de materiais naturais como a fibra de curauá se tornam objetos de ...
