Resumen
This work examines the morphology, mechanical and thermal properties of biocomposites based
on epoxy resin-EP and fque (Furcraea andina), a native crop of South America. The EP-fque
biocomposites were prepared using fque powder-FP an industrial waste generated during fque
processing, nonwoven fque fber mats-NWF and unidirectional fque fber mats-UF oriented at 0° and
90°. The addition of fque into EP matrix restricts EP macromolecule chains movement and enhance
the thermal stability of EP. SEM images showed that fque form used (powder or fber) and mat
arrangement can generate changes in the biocomposites morphology. Mechanical characterization
show that fque powder and fque fbers oriented at 90° acts as fllers for the epoxy matrix while the
fque fbers oriented at 0° reinforce EP matrix increasing the tensile and fexural modulus up to 5700
and 1100% respectively and tensile and fexural strength up to 277% and 820% in comparison with
neat EP. The obtained results can increase the interest in researching and developing products from
fque Powders and other natural fbers processing byproducts thus reducing the abundance of waste
in soil and landflls and environmental concerns and suggest that the EP-fque biocomposites are
promising to be used in the automotive sector
