Material Qualities on FIber Reinforced Metal Used as Renforcement for Pistons of Engiens in Automobiles
Details
The purpose of this research is to verify material qualities of fiber reinforced metal (FRM) that is used to reinforce pistons for engines of automobiles. The target of FRM in the present research is composed of metal mibers, Fe_<75>Cr_<20>Si_5 and matrix of aluminum alloy, AC8A. Tensile and compression tests were carried out on materials of 100%-AC8A and FRM under temperature conditions of 25℃, 150℃, 250℃, 300℃. Stresses and strains were measured by the tests. Young's moduli and Poisson's ratios were also found through the experimental results. Then Young's moduli were calculated using the proposed models and formulation.
