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…
In this study, material use fiber glass and plywood skin while using epoxy type adhesive and an eagle (PVAc). Fiber volume fraction of 15% by weight, with length of the distance between holes is 40 mm. Tests performed is test density refers ASTM C - 271 standard, the test press the edges according to ASTM C364-99, bending test which refers to the standard ASTM C – 392, and water absorbti…
Adhesives are widely used for shipping industry, epoxy adhesive usually used as matrix composite and adhesive on the structure hull. These sections are often exposed to water which can affect the mechanical properties of epoxy. This study aims to determine the effect of differences absorption distilled water and salt water into the epoxy adhesive specimens, as well to determine the effect o…
Composite is combination of two or more materials which are arranged in a certain manner to reach new characteristics in the result of materials. Therefore, making the composite board by the variation of fiber determination and adhesive types are one of the way to get new material properties. This study aims to determine the nature of the bending strength and impact toughness of composite b…
ABSTRACT Adhesives joint have been widely used in the automotive industry, aircraft industry and electronic industry. However when adhesives joint are exposed in wet environment it may affect the strength of the joints. The study aims to determine the steel composite bonding and failure mode when the thickness of the adhesive was varied. The joints were made from low carbon steel and compo…
Kayu jati (Tectona grandis) tergolong dalam kelas kuat I dan kelas awet I yang berarti sangat awet sehingga relatif tidak mudah lapuk, meskipun demikian pelapukan tetap akan bisa terjadi dalam jangka waktu yang lama dan memiliki berat jenis 0,62-0,75 kg/m3 dan berat jenis air murni 1000 kg/m3 (BKI, 1996). Adapun tujuan yang ingin dicapai dalam penelitian ini adalah : Mengetahui pengaruh perubah…
