The purpose of this research is to know the effect of fraction of fiberglass volume as one skin and coconut fiber fraction volume as skin two to density and bending strength on hybrid sandwich composite material with sengon sawdust core. The main ingredient of this research is sengon wood sawdust, fiberglass, coconut fiber, unsaturated polyester resin and hardener. This experiment was testing t…
Sandwich composites are widely used in the automotive industry, property, electronics and shipbuilding. Especially for industrial property sandwich composites can be used as a wall or a building lantain. The purpose of this study was to determine the effect of bamboo fiber volume fraction on the density, compressive strength and bending strength of the composite material foam core sandwich with…
