Plastery matrix composites reinforced with palm fiber from the Amazon Region
Abstract The objective of this study was to evaluate the performance of petiole reinforcement of jupati (Raphia taedigera), a palm from the Amazon region, in gypsum matrices. Jupati petiole is a porous material with a lower density than gypsum and has a basic composition of holocellulose, lignin and extractives. For our study, the specimens were prepared with a water/gypsum ratio of 0.6 and a gradual addition of the petiole in relation to the gypsum mass (0.0%, 2.5%, 5.0%, 7.5% and 10.0%). The influence of this incorporation was evaluated through physical, mechanical and microstructural tests. The results showed that the insertion of the jupati petiole caused a decrease in the density and an increase in the water absorption of the composites. Due to the high porosity of the particles, good acoustic performances were achieved. However, regarding the mechanical properties, a good performance was not observed due to the low interaction of the reinforcement/matrix; this result was confirmed by the microscopic images.

Highlights The valorization of raw materials in the Amazon rainforest was achieved. The low density of lignocellulosic particles was evaluated. The acoustic insulation of the gypsum composites was improved. The relationship between the porosity and physical-mechanical characteristics of composites was determined.
