A truck bed or liner for installation in a pickup truck bed or cargo vehicle exhibits improved electrical charge dissipating characteristics. The preferred embodiment bed is manufactured of high density polyethylene (HDPE) or similar material containing particles of conductive material such as carbon black dispersed therethrough. In a first alternate embodiment, the bed defines a two-layer composite or sandwich. The upper layer of HDPE or similar material includes dispersed carbon black particles whereas the lower layer is free of such particles. A second alternate embodiment of the invention comprehends a bed liner for disposition in a pickup truck or the like wherein the conductive material is dispersed throughout the liner material. In a third alternate embodiment, the bed liner of the second alternate embodiment is combined with the composite conductive and non-conductive layers of the first alternate embodiment. In a fourth alternate embodiment, a bed or liner of HDPE or similar material includes an open mesh fabric or webbing which has carbon black particles dispersed therein. The mesh or webbing is secured to the upper surface of a liner made of HDPE, preferably by autogenous bonding. Additional embodiments are manufactured of fiber reinforced plastic (FRP).

Charge dissipating bed liner

A liner for installation in the bed of a pickup truck or cargo vehicle includes a bottom panel bounded by vertical walls and a friction enhancing material secured to the upper surface of the bottom panel. The material is preferably an open mesh fabric or webbing which may be woven but is preferably extruded in order to ensure bonding of threads or filaments at their intersections. Preferably, as well, as the webbing is made of material similar to the material of the bed liner which is typically high density polyethylene (HDPE) in order that appropriate autogenous bonding between the liner and mesh may be achieved and furthermore that the liner, mesh and manufacturing scrap may be readily recycled.
