Perkembangan teknologi di dunia kedirgantaraan semakin maju. Ketergantungan pada bahan buatan yang semakin tinggi menuntut terciptanya inovasi untuk mengembangkan material yang ringan namun tetap kuat tanpa meninggalkan aspek-aspek keselamatan. Perkembangan teknologi komposit makin serius di kembangkan. Salah satunya teknologi komposit dengan material serat inti busa (fiber foam core). Dalam penelitian ini variasi yang digunakan adalah lapisan bagian atas 1 sampai 3 lapisan. Pembuatan material menggunakan metode hand lay-up, spesimen menggunakan standar ASTM D 638 dan ASTM C 393. Pengujian tarik dan bending dengan pengulangan 3 kali. Dari hasil penelitian menunjukkan bahwa kekuatan tarik dan Bending tertinggi di dapat pada 3 lapisan atas komposit karbon fiber core styrofoam sebesar 605,38 kg/cm2 dan untuk pengujian Bending 702,7 kg/cm2. Kata kunci: Komposit Karbon, Uji Bending, Uji Tarik
