Microstructure observation of the composite specimens was focused on the distribution of alumina reinforcement particles in different orientations. It was found that Composite 1 showed a more evenly distributed particles compared to that of Composite 2. The measurement of sonic modulus was carried out by using GrindoSonic MK5 Industrial Instrument. All the sonic modulus properties (flexural, longitudinal and torsional moduli) of Composite 2 were found to be higher than Composite 1. The testing of impact strength was done by means of Charpy impact test (V-notched specimen). It has found that the impact strength of Composite 1 (5.42 J) was higher as compared to Composite 2 (4.07 J). The fracture surfaces after impact test for the composite samples were investigated by using scanning electron microscopy in order to characterise the fracture mechanism of the composites. The fracture mechanism of Composite 1 was Indicated by matrix ductile rupture and decohesion of particle-matrix Interface, whereas matrix brittle rupture by particle fracture was found in Composite 2. 2008-09-15T07:26:16Z 2008-09-15T07:26:16Z 2004 Article Journal of Engineering Research and Education, vol. 1, 2004, pages 45-53. 1823-2981 http://hdl.handle.net/123456789/2207 http://www.unimap.edu.my/ en Kolej Universiti Kejuruteraan Utara Malaysia
