Filler banyak digunakan untuk meningkatkan sifat mekanik epoxy yang digunakan sebagai perekat. Beberapa filler mempunyai keunggulan dan kekurangan sehingga hibridisasi filler dapat mengurangi kekurangan masing-masing filler. AdapunTujuan dari penelitian ini adalah untuk mengetahui pengaru komposisi filler hybrid fly ash dan CaCo3 terhadap kekuatan geser perekat sambungan baja dan mode kegag…
The nano-sized CaCO3 filler material has unique properties caused by the large surface or mixed surface fraction with epoxy adhesives that can change the adhesive properties, especially viscosity, water absorption properties and increase adhesive strength. Therefore nano-CaCO3 filler is used as an epoxy adhesive mixture. The purpose of this study is to know the effect of nano-CaCO3 fille…
Composite is a combination of several different materials, arranged to form new materials that are better than the nature of the arrangement. Composites are distinguished by their shape, which is in the form of particles, fibers and a combination of particle and fiber shapes. Sandwich composites are formed from two rigid skins and separated by a core and bound by an adhesive. The main ingredien…

A filler is an ingredient that is commonly mixed in epoxy adhesives to change adhesive properties, especially viscosity, water absorption properties and can increase adhesive strength. There are many fillers that can be used to improve the properties of epoxy adhesives such as flay ash, pumice, cement, CaCO3, and glass. Therefore, the filler can be used as an epoxy adhesive mixture. The purpose…
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…
Sambungan perekat banyak digunakan di dalam industri otomotif, dan industri perkapalan. Seiring dengan perkembangan teknologi yang semakin pesat ini, pemakaian sambungan pun semakin meningkat. Penggunaannya banyak ditemukan pada konstruksi yang terbuat dari logam, komposit, kayu dan keramik. Adapun tujuan dari penelitian ini adalah untuk mengetahui pengaruh media dan waktu perendaman pada keku…
