Abstract: A fibrous substrate comprising a consolidated product of a fiber composition is provided comprising polyimide fibers; fibers selected from aromatic polyamide fibrids or polycarbonate fibers; aromatic polyamide fibers. A process of preparing a fibrous substrate is disclosed, comprising forming a layer from a slurry comprising a suspension solvent; and fiber composition comprising a combination of polyimide fibers; aromatic polyamide fibers; aromatic polyamide fibrids; each based on the total weight of the fibers in the fiber composition; dewatering the layer; and consolidating the layer to form the fibrous substrate; wherein a layer of polyimide fiber aromatic polyamide fibrid is applied to each surface of the fibrous substrate either before or after said consolidating step, and the substrate and polyimide layers are together subjected to a consolidating step. In another embodiment, articles comprising the above fibrous substrates are provided.

Abstract: A material handling container (10) of the type for packaging, shipping and inventorying goods and of the type for stacking one upon the other when not in use, made of molded thermoplastic and having a plurality of plastic reinforcement members (86) arranged in predetermined positions about the plastic planer expanses (84) of the container (10) for adding strength and stiffness. The reinforcement members (86) define a plurality of hollow channels (88) disposed adjacent to the planer expanses (84) of the container (10) and including at least one rib (90) extending upwardly from the channel (88) defined by the reinforcement member (80) for adding strength and stiffness to the planer expanse (84) of the container (10).
