Mechanical and thermal behavior of hybrid glass/jute fiber reinforced composites with epoxy/polyester resin

Polimery 2019, No 7-8, 499

Summary

The hybrid glass/jute fiber composites were fabricated by hand layup (HL) and vacuum assisted resin transfer molding (VARTM) method using epoxy and isophthalic polyester resins as matrices. The effects of fiber and matrix typeas well as fabrication method on the tensile and flexural mechanical strength of resulting composites were investigated. The morphological fracture was analyzed based on scanning electron microscopy (SEM) images. Also, the curing characteristics of two matrix resins was studied by using differential scanning calorimetry (DSC). For glass fiber composite, the curing rate of polyester resin is faster at 100 °C than that of composite with epoxy matrix. Using VARTM process, the composite with high fiber volume fraction (Vf) of 52% was obtained.
