BIOCOMPÓSITO DE POLIÉSTER REFORÇADOS COM A FIBRA DA FOLHA DE LICURI (Syagros coronata)
(Universidade Federal do Pará, 2014) SANTOS, Manfrine Silva; FUJIYAMA, Roberto Tetsuo
The northeastern hinterland is endowed with rich flora and abundant thus making a major supplier of plants provides the development of new polymeric composites. This dissertation aimed to the evaluation of the mechanical properties of composites reinforced by polyester fibers Licuri using a whole manual process, in order to provide the making of the material with the lowest possible technological level, thus becoming a totally viable material. The fibers were randomly dispersed in the composite, and the matrix used was pre-accelerated terephthalic polyester with cobalt naphthenate and cured at room temperature with methyl ethyl ketone peroxide (MEK) in a ratio of 0.33% (v / v). The results showed that the tensile strength increased with fiber length (5mm - 13.47 MPa, 10mm - 14.5 MPa and 15mm - 16.97 MPa), demonstrating that the investigated composites are potentially viable.
