Abstract
A structurally reinforced blow molded assembly includes an overmold body bonded to one or more preformed internal stiffening ribs. The reinforcing r ribs are partially encapsulated by o the overmold body in an orientation selected to carry load a forces thereon. The resin mixture used to form the overmold body comprises 10% to 40% by weight short glass having a length less about 15 cm, and 60% to 90% by weight thermoplastic resin. To facilitate recycling the reinforcing ribs comprise 30 to 60% by weight long glass fibers and 40% to 70% of thermoplastic bonding resin.
