Resumen

DIAZ-BATISTA, Daniel et al. Profiles from Henequen Fibres with High-Density Polyethylene Matrix. Rev Cie Téc Agr [online]. 2018, vol.27, n.1, pp.22-35. ISSN 2071-0054.

A process to obtain profiles from henequen (Agave fourcroydes Lem.) fiber reinforced high-density polyethylene (HDPE) matrix composite material by extrusion method is presented. Data on thermal stability and microstructural features of the henequen fibers used are presented. Behavior of material in process and its influence on mechanical properties are analyzed. A comparison between obtained material and another currently in production and incorporating wood particles from pine sawdust (Pinus sp.) as reinforcing element is exposed. Tensile strength of henequen fiber reinforced composites ranges from 12 to 15 MPa, slightly lower than the one obtained from wood particle reinforced composite material. Nevertheless, the impact strength and Young’s modulus values double the ones obtained with pine’s particles reinforcement. Characterization of both materials obtained and process, it allowed to both identify elements related to differences on tensile strength and propose processing alternatives to allow introducing henequen fibers.

Palabras clave : lignocellulose fiber; composite; thermoplastic; henequen; polyethylene.
