Abstract: A wiper apparatus includes a wiper arm extending from a first wiper arm end to second wiper arm end. The wiper arm has an airfoil profile. The wiper arm includes a core having a lattice structure with shell extending around the lattice structure. A composite layer is formed around the core. The composite layer conforms to an outer surface of the shell. A method of making a wiper apparatus includes forming a core of a wiper arm with a lattice structure surrounded by a shell. The method includes depositing a layer of composite material on an outer surface of the shell.
