Analisa Tensile Strength Komposit Serat Kulit Pohon Waru dengan Kombinasi Serat Karbon Kevlar Sebagai Material Reinforcement

In increasing the tensile strength of waru tree bark fiber composite (Hibiscus tiliaceus), it is necessary to have a combination reinforcement used in material. One materials that can be combined carbon kevlar. Kevlar has several advantages, including low density, absorbing vibrations well, and resistant chemical solutions. The specific objectives this study were determine maximum strain stress, modulus elasticity, fracture analysis hibiscus composites with kevlar as independent variable was comparing different used, 100% tiliaceus) fiber, 50% bark, carbon. process making uses vacuum infusion resin method specimens referring ASTM D638-03 type I standard. results are combining material improve mechanical properties terms composite.
