CARBON FIBER WITH NI-COATED REINFORCED ALUMINUM MATRIX COMPOSITES

摘要

The aluminum matrix composites reinforced by carbon fiber have attractive properties. But manufacture of aluminum matrix composites reinforced by carbon fiber have been limited by low wettability and interfacial reaction between carbon fiber and molten aluminum. The nickel coated carbon fibers can improve the wettability between carbon fibers and aluminum, and can inhibit the harmful interfacial reaction for its stable coating structure, so nickel plating is a simple and easy method to improve the surface behaviour of carbon fiber.This paper introduces the process of electroplating with nickel on carbon fiber. Microscopic structure of nickel coating and the effect of nickel plating rate and coating structure with the solution composition, current density and electroplating time have been studied. The principle of nickel plating is also researched. The aluminum matrix composites is reinforced by carbon fiber with nickel coating, and the composite effect between aluminum and carbon fiber is observed.
