Abstract

Telah dilakukan penelitian mengenai pengaruh rasio hardener dan resin pada komposit serat rambut manusia. Limbah rambut kering yang sudah bersih dan direndam dalam NaOH 1 M selama 60 menit dibilas dengan air bersih dan dikeringkan. Serat rambut yang sudah kering ditambahkan pada matrik dengan rasio fraksi volum tetap (serat:matriks, 30%:70%) untuk dibuat material komposit. Sedangkan rasio epoxy dan hardener dengan perbandingan yaitu 50%:50%, 60%:40%, 70%:30%, 80%:20%. Katalis yang digunakan untuk komposit dengan resin polyester yaitu 1 tetes, 2 tetes, 3 tetes, dan 4 tetes dengan volume cetakan 11,69 ml. Hasil dari pengujian ini didapatkan kekuatan mekanik tertinggi untuk komposit serat rambut manusia dengan matrik epoxy yaitu sebesar 4,5 kgf/mm2, elongasi 6,32%, dan densitas 1,0908 gr/ml pada perbandingan resin dan epoxy 60:40. Sedangkan pada komposit serat rambut manusia bermatriks polyester kekuatan mekanik tertinggi yaitu sebesar 3,4 kgf/mm2, elongasi 3,84% dan densitas 1,23 gr/ml pada jumlah katalis 4 tetes. =============================================================================================== The effect of resin and hardener on human fiber composite have been successfully carried out. Dried and cleaned human hair soaked in NaOH 1 M for 60 minutes, and then rinsed by aquades followed by convective drying. This processed hair was added in the matrix in a constant volume fraction ratio (fiber:matrix = 30%:70%). Variation epoxy and hardener used was 50%:50%, 60%:40%, 70%:30%, 80%:20%. The amount of catalyst employed was also varied; 1.e. 1 – 4 drops in a constant volume of mold; i.e. 11.69 ml. The highest properties obtained for human hair reinforced epoxy matrix were 4.5 kgf/mm2, 6,32% and 1.0908 gr/ml for tensile strength, elongation and density, respectively. The above data was obtained for resin-to-epoxy ratio of 60:40. Whereas for human hair reinforced polyester matrix, it was obtained 3.4 kgf/mm2, 3,84% and 1.23 gr/ml for tensile strength, elongation and density, respectively, for sample with catalyst amounts of 4 drops.
