Abstract

In this study, biocomposite profiles, in the dimensions of 40x40x1100 mm, were produced. Biocomposites consisting of polyester resin glue and banana fibers as a filling material and glass ropes binding were prepared by compression moulding technique under 400 bar pressure and at 70 °C temperature using a hydraulic pres. In order to gain higher strength on the outer surfaces of the produced profiles, glass fiber and polyester binding were used. One and two fold glass fibers were laid down in two different orientations. One of them was laid by hand lay-up method which was used to increase strength of the outer surfaces. The bending test was applied to the produced specimens in the dimension of 40x40x550 mm. The flexural strength values were calculated according to TS EN 310 using the obtained Fmax values. The test results showed that the highest and lowest bending strengths for a single layer specimen were 13.085 N/mm² and 8.957 N/mm², respectively. While, the highest and lowest bending strengths for the double layers specimens were 18.196 N/mm² and 16.834 N/mm², respectively. From these results it can be concluded that these composites can be used in various structural components for the greenhouse industry and stair handrails, fencing and decoration for garden furniture
