PENGARUH PERLAKUAN PERMUKAAN PARTIKEL KARET BAN BEKAS TERHADAP SIFAT TARIK K…

Epoxy thermosets termasuk kelompok polimer yang bisa digunakan sebagai bahan pelapis perekat, dan sebagai matriks (pengikat) pada matrial komposit. Untuk meningkatkan sifat modulus elastis epoxy perlu ditambahkan filler. Tujuan yang ingin dicapai dalam penelitian ini adalah untuk mengetahui pengaruh perlakuan permukaan partikel karet ban bekas terhadap sifat tarik komposit partikel kare…

PENGARUH RASIO PEREKAT EPOXY RESIN TERHADAP HARDENER DENGAN FILLER NANO-CaCO…

Epoxy is a thermoset synthetic product of polyepoxy resin reactions with hardening substances. In addition epoxy is also able to maintain the mechanical properties of a material in a wet environment, which is very important because it determines the quality of the material itself.The purpose of this study is to find out the effect of the ratio of epoxy resins to hardeners on the strength of…

KEKUATAN GESER SAMBUNGAN LAP JOINT BAJA KARBON RENDAH DENGAN PEREKAT EPOXY B…

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…

PENGARUH KANDUNGAN FILLER NANO-CaCO3 TERHADAP KEKUATAN GESER SAMBUNGAN BAJA …

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…

Kekuatan Luluh Tekan Komposit Partikel Berfiller Hybrid Fly Ash Dan Caco3 Dal…

Epoxy is a brittle thermoset polymer and is able to withstand heat that evaporates in water and has advantages such as good mechanical properties, good adhesion and low shrinkage. However, mechanical properties can still be improved by adding other materials as modifiers that are correct to certain properties to maintain mechanical properties in a material in a wet environment. For this reason,…

Pengaruh campuran epoxy variasi filler hybrid (fly ash dan CaCO3) pada kondis…

Fly Ash and CaCO3 have their own advantages for filling epoxy, in terms of water absorption and side tensile strength, so hybrid fly ash and CaCO3 need to be investigated further. The purpose of this study was to determine the effect of hybrid filler combination (fly ash / CaCO3) on water absorption and tensile strength tested in dry and wet conditions. The main ingredients of this research are…

KETANGGUHAN RETAK CAMPURAN EPOXY VARIASI FILLER HYBRID (FLY ASH DAN CaCO3) PA…

Keywords: epoxy, water absorption and fracture toughness. Filler is widely used to improve the mechanical properties of epoxy which is used as an adhesive. Some fillers have advantages and disadvantages so that filler hybridization can reduce the deficiency of each filler. The purpose of this study was to determine differences in water absorption in various hybrid filler compositions (fl…

KINERJA CAMPURAN ASPHALT CONCRETE WEARING COURSE (AC-WC) MENGGUNAKAN ASPAL TU…

Melihat peningkatan mobilitas penduduk yang sangat tinggi diperlukan peningkatan kualitas pembangunan prasarana transportasi jalan yang efisien dan efektif. Umumnya penanganan kerusakan perkerasan dilakukan dengan memberi lapis tambahan. Salah satu penyebab penurunan kekuatan campuran pada perkerasan lentur adalah proses penuaan dan untuk mengurangi tingkat penuaan digunakan peremajaan. Propo…

PENGARUH FRAKSI VOLUME FILLER (Fly ash, CaCO3, dan Semen) TERHADAP KEKUATAN T…

Epoxy thermosets include polymer groups commonly used as adhesive coating materials, and as a matrix (binder) on composite materials. To increase certain properties (modulus of elasticity), the filler needs to be added. The purpose of this study was to determine the effect of the volume fraction on the tensile properties of epoxy for various fillers, fly ash, CaCO3, and cement. This research m…
