Abstract
Nogogeni merupakan mobil riset ramah lingkungan dan hemat energi yang dirancang untuk mendapatkan efisiensi tinggi. Untuk mencapai rancangan tersebut maka tim harus mereduksi berat pada kendaraan. Salah satu upaya untuk mereduksi berat mobil adalah dengan menggunakan komponen mobil dengan material dasar yang lebih ringan, maka nilai efisiensi akan bertambah baik
Untuk mendapatkan komponen mobil yang ringan maka dipilihlah komposit sandwich serat karbon fiber dan double layer alumunium honeycomb core dengan variasi arah serat. Tujuan dari tugas akhir ini adalah untuk membantu tim Nogogeni mendapatkan altematif pemilihan bahan dasar yang ringan namun tidak mengesampingkan kekuatan material.
Setelah dilakukan pengujian bending diketahui bahwa data pengujian menghasilkan stiffness sebesar 1370.36 N/mm, facing bending stress 184.405 MPa, core shear ultimate stress 0,792 MPa komposit yang terbaik terdapat pada arah serat 0, juga hasil momen bending karbonfiber dan double layer aluminum honeycomb core lebih besar 517.62% dibandingkan dengan alumunium alloy 6063 T6-6h, model kegagalan komposit sandwich serat karbonfiber dengan double layer alumunium honeycomb core akibat pengujian bending (three point bending) berupa kegagalan indentation dan kegagalan core shear.

Nogogeni is an environmentally friendly and energy efficient research car designed toget high efficiency. To achieve this design, the team must reduce the weight of the vehicle. One effort to reduce the weight of a car is to use car components with lighter base material, so the efficiency value will improve.
To get lightweight car components, a carbon fiber fiber sandwich composite and double layer aluminum honeycomb core were selected with variations in the direction of the fiber. The purpose of this final project is to help the Nogogeni team get an alternative selection of basic materials that are lightweight but do not rule out material strength.
After bending testing it is known that the test dataproduces stiffness of 1370.36 N/mm, facing bending stress 184.405 MPa, ultimate core shear stress 0.792 MPa composite is bestfound in the direction of fiber 0, also results in bending moments of carbonfiber and double layer aluminum honeycomb cores large 517.62% compared to 6063 T6-6h aluminum alloy, failure model of carbon fiber fiber sandwich composite with double layer aluminum honeycomb core due to bending test (threepoint bending) in theform of indentationfai lure and core shearfailure.
