Specimen Test Making of Polypropylene High Impact (PPHI) Polymer Composite Reinforced with Natural Fibres using Hand Lay-Up Methods

Pineapple and hemp are one type of natural fibre that is widely grown in Indonesia and has good mechanical properties. The use of hemp and pineapple fibres as reinforcing and high impact polypropylene (PPHI) materials that are widely used in the automotive industry as a matrix in composites for applications in the automotive field studied. In this research, the process of making bending test specimens using ASTM D 69 standard for PPHI reinforced composites and pineapple fibre uses the hand lay-up method, with meshing below 120 and 10% volume fraction. As a result, in order to make homogeneous specimen, good setting at temperature 250 ℃ by normalizing cooling and stirring process to enable PPHI and pineapple fibre.
