The composite sandwiches have been developed and produced for various aspects of life. Unsaturated polyester content combined with pin from plants such as the pin of bamboo plants that grows around here and polyurethane rigid foam as the core. The method of sandwich composite joints is very important when applied to construction such as window panels, walls, roofs, floors, and others. The method of angular spacing between pin and core Z-pin model is the discussion in this study. This study takes two models of research method that is the angle and distance between pins to be calculated in two tests the shear tensile and tensile tests. Composite sandwiches are made by hand lay-up method. The skins are made from a thin reinforced polyster resin with glass fiber fibers, while the cores are made of polyurethane rigid foam and added Z-pins from bamboo materials. Core are bonded between two outer skin layers. Z-pins made of bamboo will be stuck on a polyurethane rigid foam core with varying angles 60 o, 75 o, 90o and spacing between pins in each 10mm, 15mm, 20mm test with each pin length is different according to the angle variations. The results show that the composite sliding strength of the sandwich composites tend to increase with the distance between pins. The largest load strength and shear stresses of sandwich composites are found in variations of the distance between pins of 10 mm with a 60o attachment angle, which average loads reach a maximum of 2206.67 N and an average voltage of 118.52 kPa at the same distance and angle. While the variation of pacing distance and pinching angle did not show a significant effect on the strength of composite sandwich sliding strength. As for the thick press testing the maximum load strength and voltage is influenced by the distance between the pins are getting denser and angles that have the appropriate slope. In thicker press testing the largest load was found with an average of 3067.78 N and the largest voltage at 828.15 kPa with an angle of 75o 10mm pin sticking distance.
