Effects Of Reinforced Materials On Mechanical Properties Of 3d Composite Structure
In this study the mechanical performance of sandwich composite panels based on “green” 3D warp knitted
composites is presented and discussed. Different 3D sandwich knitted fabric performs have been produced in which leek and
bamboo fibers were used with the comparison of carbon fiber as reinforcement for “green” composites. Composite panels
using these performs have been produced using hand lay-up technique. Experimental results revealed that the polyester resin
reinforced by the 3D knitted spacer fabrics with reinforced fibers exhibited improved tensile, three point bending and impact
behaviors. The obtained results show that the mechanical performances vary according to the type of reinforced fibers.
Index Terms- green composite, three-dimensional, spacer fabric, high performance.
