Abstract

The composite sandwiches have been developed and produced for various aspects of life. Unsaturated polyester content combined with pin from coconut leaf bone that grows around us and polyurethane rigid foam as core. The method of sandwich composite joints is very important when applied to construction such as window panels, walls, roofs, floors, and others The Z-pin angle variation and Z-pin variation are discussed in the study This study takes two models of research method that is the angle and the pin type into the calculation in two tests also the bending and pull test. Composite sandwiches are made by hand lay-up method. The skins are made from a thin polyster resin reinforced with glass fiber fibers, while the cores are made of polyurethane rigid foam and added Z-pins from the coconut leaf reinforcement material. Core cores are bonded between two outer skin layers. Z-pin made of stick will be stuck on polyurethane rigid foam core with variation of angle 60o, 75 o, 90 o and distance between pin 15 mm with each pin length different according to the variation angle. The results showed that the variation of Z-pin angle in the composite sandwiches will vary the load and bending strength. The optimum bending load and strength is obtained at the pin 7575 pinching angle in which the optimum load reaches 835.54 N and the average bending power of 173 N / mm² on the Z-pin K type. While for the Z- pin type that significantly affects the bending force composite sandwiches. As for tensile strength and tensile
