Abstract
ABSTRACT In this work, compressive and interlaminar shear properties of hybrid laminates were evaluated in order to fulfill the gap regarding the analysis of these mechanical properties and their importance for hybrid composites with natural fiber. Laminates of epoxy and jute fabric with non-woven glass fabrics were manufactured by vacuum infusion. Three hybrid laminates were produced with different orientation of their layers. Fiber weight fraction was 60% and density was 20% lower than glass fiber-reinforced composites. The hybrid laminates with jute fabric showed lower compressive and interlaminar shear strength compared to the glass fiber laminates, and the best compressive strength result was presented by the hybrid laminate with layers oriented 0/90°. The fractures of laminates were evaluated by an optical microscope. In the hybridized laminates, mainly in short beam testing, the failures occurred between jute layers whereas in compression failures were identified in the bordering surface of the glass and jute layer and in some regions with excess of resin. These results suggest that the hybrid laminates configurations developed and analyzed in this work can be successfully applied to mold components in composites, arising as an environmentally friendly option to the glass fiber-reinforced composites.
