In this paper we build some composite materials reinforced with corn leaves. order to the samples, have firstly created strips in way: put leaves, continuously, on a sheet of where apply layer resin (we used epoxy and polyester ones). We waited for polymerization 48 hours, recommended by producer. leaves layers director tensile test (because will samples tensile). made 10 glued them together us...

In this study, the effects of incorporating recycled photopolymer-plate residues from a packaging flexography process into polyester-glass fiber composites were examined. Ternary with an unsaturated polyester matrix elastomer particles evaluated using two types glass fibers: in forms fabric bidirectional fibers and blanket multidirectional fibers. The prepared by hand lay-up lamination differen...

Three kinds of fiber reinforced plastic (FRP) composites, including modified polyurethane resin (LGD), epoxy resin (E44) and modified unsaturated polyester resin (D33) glass-fiber reinforced plastics, were subjected to a 5000 h multi-factor accelerated aging test according to the power industry standard. To examine aging resistance and thermal stability of transmission towers made by these thre...

The present work study flexural and tensile behavior of short Kenaf fiber reinforced composites. The fibers are chemically treated in 2% NaOH solution at room temperature. Short fibers of 4mm and 8 mm are used in the present work. The composite lamina is prepared by hand molding using isopthalic polyester resin. Flexural test and tension tests are carried out as per ASTM standards. The flexural...

This work presents an alternative to studying and determining the torsion modulus, G, in composites. For this purpose, we use a measuring system with rotation motion sensor coupled pendulum that allows for angular position as function of time. Then, through equation derived from mechanical spectroscopy studies permits calculation G’s value, experiments focus on samples different quantities calc...
