Article History: Received Accepted Available online Along with the development of the manufacturing industry, the use of composite materials that are environtmentally friendly and can be recycled is a demand of current technology. Then, efforts need to be made with the use of natural fiber reinforced composite material which is one of the composite materials that can be ex…
Sandwich composite has been developed and produced for various aspects of life today. The unsaturated polyester content combined with palm fiber from plants such as palm fiber from palm trees that grow around us and polyurethane rigid foam as the core. The sandwich composite connection method is very important when applied to construction such as making boats, railroad bodies and others. The m…
Article History: Received Accepted Available online 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 win…
Hybrid sandwich composite is a sandwich composite material more than one layer composed of fiberglass composite and fibricius composite as skin and core in the middle. Composite materials are fiberglass is very easy to obtain affordable economics, coconut husk and sengon wood powder is an abundance of waste is very easy to get on the island of Lombok. This research was conducted to investigate …
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…
Composite sandwich can be used as an alternative or substitute conventional metallic materials that have strength and stiffness are promising, the density is low enough, the resistance to free environment (corrosion). The use of waste as materials for composite sandwich is a solution creatively to enhance the utility value of waste and is an effort to reduce environmental pollution. This re…
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…
