Discontinuously Reinforced Aluminum Composite and Its Application in Brake Discs

Abstract

Discontinuously reinforced aluminum (DRA) composites are attractive for a large range of engineering applications because of its excellent wear-resistance, high thermal conductivity and light weight etc. In this paper, DRA composites were designed and fabricated especially for automotive application, and their properties were measured. Brake discs of DRA composites were manufactured and their braking performances were investigated, including brake velocity, brake pressure, brake torque, brake deceleration, brake time and surface temperature etc. The test results show DRA composites exhibit an excellent braking performance.

Residual stress and damage development in the aluminium alloy EN AW-6061 particle reinforced with Al2O3 under thermal fatigue loading

“…The effect of thermally induced local deformation on the averaged residual stresses increases with increasing V p due to an increasing amount of deformations adaptation between particles and matrix. Increasing T max shows a similar effect in consequence of generally higher thermally induced plastic deformations [9,10,25,35,46,47]. (4) Mechanically induced, local deformation occurring inside the matrices of the MMCs near the interfaces due to different stiffness of matrix and particles and different deformation behaviour [1,49,50].…”
