Abstract

Natural composites now being developed in order to shift the presence of synthetic composites which tend valuable expensive and not environmentally friendly. One of the natural potential that has not been widely used as a reinforcement of composites is waste Java goat hair pieces obtained from the home tanning goat skins. But before it can be used as reinforcement in composite materials must be known physical and mechanical properties of the material. The purpose of this study was to describe the tensile strength of the composite polyester fiber goat hair due to the influence of chemicals percentage of NaOH and describe macro photographs after tensile testing due to the influence of the percentage of NaOH. The initial process of soaking the fiber using a solution of NaOH chemicals with their respective percentage of 4%, 5%, 6% and 7% for 60 minutes. Further drying is done under the sun to dry. Then the fiber is cut into pieces with a length of 10 mm. Manufacture of composites using hand lay-up with a percentage of 30% fiber volume fraction and composite tensile test performed with standard ASTM D 638-02 and macro photographs fracture results from a composite of polyester fiber goat hair. The results showed that the influence of the percentage of NaOH solution of chemicals used in immersion goat hair fibers affect the mechanical properties of the resulting composites. Fiber-reinforced composites goat hair with the effect of the percentage of 5% NaOH for 60 minutes has the highest tensile strength of the price that is equal to 19 254 MPa. This is evident from the results of the macro image of composite structures are cross-sectional fracture fracture evenly and not too showed fiber pull-out.
