Daftar Isi:
- The purpose of this study to analyze the tensile strength and flexural strength of widuri fiber reinforced polyester. Treatment with 5% NaOH for 1 hour. Directions random fiber orientation with a fiber size of 1 cm, 3 cm and 5 cm. The test specimen is printed with a printing press method, the fiber volume fraction of 30%, polyester resin binder. The test specimens were performed according to ASTM testing standard ASTM D638 to for tensile and D790 to flexural test. The calculation result obtained an increase in the tensile strength fiber length of 5 cm is 43.0809 MPa. While the value of the highest tensile modulus of elasticity of the fiber length of 3 cm. While testing the flexural obtained the highest bending strength in the fiber length of 3 cm is 62.8874 MPa and flexural strength values were lower in fiber length of 5 cm. While the value of the highest flexural modulus of elasticity of 3.1325 MPa with a fiber length of 5 cm and the lowest fiber length of 3 cm, for the highest value of 6509.916 Nmm flexural moments on the fiber length of 3 cm and the lowest value of flexural moment of the fiber length of 1 cm. From the results of photo fracturing shape tensile test specimens showed that the fiber length of 1 cm, 3 cm, 5 cm is a fault caused by a failure in the weight-bearing matrix. The images form flexural fracture test specimens showed that the fiber length of 5 cm is a fault caused by a failure in the weight-bearing matrix, whereas the fiber length of 1 cm and 3 cm showed the form fracture caused by the failure of fiber in weight-bearing
