REINFORCED BLOW MOULDED VEHICLE RUNNING BOARD AND METHOD OF MAKING SAME

摘要

A structurally reinforced blow moulded assembly includes an overmould body bonded to one or more preformed internal stiffening ribs. The reinforcing r ribs are partially encapsulated by o the overmould body in an orientation selected to carry load a forces thereon. The resin mixture used to form the overmould 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.
