Abstract
The use of environmentally friendly materials that is able to be recycled and be able to be destroyed itself by nature is a requirement of today's technology. The advantages of composite sandwich is lightweight but has high rigidity. Composite sandwich consists of a core(core)of honeycomb or foam with a very low density and thin and stiffskins. This study aims to determine the density,strength ofbending and compressive strength of the composite of material sandwich core with foamof bamboo, andto determine the mechanical and physical properties of the composite sandwich with the variations in fiber volume with the opened cellcore foamof bamboo. In this study, bamboo was used as raw material for the core(core)of the composite sandwich. Polyurethanewas used as a matrix binder bamboo fiber and plywood into the skin (leather). Fiber volume fractions to make the core were 2%, 4% and 6% with a fiber length of 10 mm. Tests done was test density which refered to standard ASTM C271, testing press the edges according to ASTM C364,test bending referring to ASTM C393, and press the thickness direction that refers to standard ASTM C365. The results of reserach showed that composite density of sandwich with the foam ofbamboo obtained reached 0.21 g / cm3.strength of Bending tends to decrease with increasing volumes of bamboo fiber, strength of lowes bending was 3.14 MPa at 6% fiber volume so that variations in fiber volume fraction havesignificant effect on bending strength. The compressive strength of thickness was highest at 6% volume fraction that was 1.57 MPa, the compressive strength increased thickness resulted variation composite fiber volume fraction sandwich significantly influenced the compressive strength of the edge. However the biggest edge compressive strength was shown in the volume fraction of 6% with a power of 2.01 MPa, the compressive strength of the edge tends to increase with increasing fiber length, after being done counting of ANOVA, fiber volume fraction variation did not affect the strength of edgewisesignificantly.
