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…
Article History: Received Accepted Available online Composite sandwich with polyurethane core and leaves of pandanussea fibers skin. Polyester use as matrix and pandanussea leaf fibers for skin composite sandwich. Between the layer skin and core applied the pressure for 6 hours in gluing process to get maximum gluing. Volume fraction of fiber as the variabel in this research. Volume fr…
Pandanus sea is an interesting alternative because it is the most widespread member of the pandanacae. This study aims to determine the effect of the volume fraction of pandanus sea fibers on bending and edge press strength composite with polyester resin.This research uses experiment method. In the manufacture specimens of experimental design for bending and edge press tests use was factorial d…
Composite sandwiches have been developed and produced for various aspects of life today. Unsaturated polyester content combined with pin from plants such as the pin of bamboo plants that grows around us 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 metho…
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…
Sandwich construction becomes an option on structures that have high stiffness with lighter weight. The principle of sandwich structure is to combine composite skin with a high elastic modulus with a lightweight composite core to obtain a rigid combination, strong but lightweight materials. However, the core made of polyurethane foam has a compressive strength and modulus close to zero in the d…
Pemakaian material ramah lingkungan yang mampu didaur ulang serta mampu dihancurkan sendiri oleh alam merupakan tuntutan teknologi saat ini. Kebutuhan komposit sandwich dapat memenuhi karakteristik suatu material dengan polyurethane yang diaplikasikan sebagai pengganti karet, besi, kayu dan plastik. Penelitian ini bertujuan untuk menghasilkan foam yang baik dari sifat fisis dan mekanik dengan …
