Composite is a material in the engineering world that is made by combining twokinds of materials that have different properties. Composite from fiber materials continue to be researched and develoved in order to become an alternative material to replace metal materials, this is due to the nature of fiber composites that are stronger and lighter than metal. The purpose of this study was to chara…
Increasing need to produce furniture whose main raw materials are made of wood will result in a lot of wood production that will be reduced. The purpose of this research is to investigate the tensile strength and bending strength of teak hybrid powder composites and coconut charcoal powder with polyester resin matrix. method used is to mix teak wood powder and coconut shell charcoal powder wi…
Indonesia has a wealth of natural fiber resources that are abundant and which have not been used optimally. Raw materials derived from natural have different properties compared to wood. Devlopment of biocomposit or composite technology by utilizing natural-derived fibers and agricultural waste, plantations will help overcome thr scarcity of industrial raw materials while preventing environment…
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…
Natural fibers are often considered as replacement fibers that are environmentally friendly compared to synthetic. applications from natural fibers develop in several sectors such as automotive, Furniture, packing and construction. The purpose of this study was to investigate the properties of the tensile strength and morphology of coconut bark fibers and banana stem fibers, which is treated al…
In the last decade, the trend of developing composite materials has shifted to the use of back-tonature fibers with several advantages including low density, renewable production, low energy production, easier processing, and good heat insulation and acoustics. One natural fiber is bamboo. Bamboo is very easy to grow and has excellent mechanical properties. Utilization of bamboo fiber has not b…
Humans have always been trying to create products that consist of a combination of more than one material to produce a stronger material. This is driven by the need for materials that can meet certain desired characteristics. This study aims to determine the effect of the volume fraction of cocos nucifera fibers on bending and tensile strength composite with epoxy resin. This research uses expe…
Composite is a material formed due to the incorporation of several materials into one and has new mechanical properties to produce a stronger material. This is driven by the need for materials that can meet the certain desired characteristics. One of the result is composite material. Composite material with fiber reinforcement is one of the expected composite materials in the industrial world. …

Composite material with natural fiber reinforcement is one of the composite materials expected in the industrial world. This study aims 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…
