Abstract
A composite component includes an inner core formed from a first composite material having discontinuous fibers. An outer sleeve is formed from a second composite material different from the first, and having continuous fibers. The outer sleeve generally surrounds and is bonded or otherwise connected to the inner core. The component is made by injecting or otherwise introducing thermoplastic fiber composite material including chopped or otherwise discontinuous fibers into a mold to form the inner core having a first portion with smooth surfaces and integrally joined to a second portion with bumps and ridges. The injected thermoplastic fiber composite material is cured and then removed from the mold. A layup including one or more surface plies of a thermoset continuous fiber composite material is then applied to the smooth first portion of the core. The surface plies then are compressed and cured in a mold.
