The trailing edge structure 12 of an aircraft wing is subjected, in use, to high temperature efflux from an aircraft's engines. Such elevated temperatures can detrimentally effect the ultimate tensile strength of the trailing edge. An aircraft wing component comprises composite material having: a first portion 14 comprising a metal matrix 16 containing reinforcing material 17; and a second portion 15 comprising a metal matrix 18 containing a plurality of hollow metal ceramic spheres 19, the second portion being adjacent a surface 20 of the composite material. The provision of two portions, one of which contains reinforcing material and the other comprising hollow spheres means that the composite material has both structural strength and heat shielding qualities where they are needed most in the component. The portion of composite containing the hollow metal ceramic spheres acts as an embedded layer of heat insulation.
