SYSTEM FOR PRODUCING A FULLY IMPREGNATED THERMOPLASTIC PREPREG

According to one embodiment, a system for manufacturing a fully impregnated thermoplastic prepreg includes a mechanism for moving a fabric or mat and a drying mechanism that removes residual moisture from at least one surface of the fabric or mat. The system also includes a resin application mechanism that applies a reactive resin to the fabric or mat and a press mechanism that presses the coated fabric or mat to ensure that the resin fully saturates the fabric or mat. The system further includes a curing oven through which the coated fabric or mat is moved to polymerize the resin and thereby form a thermoplastic polymer so that upon exiting the oven, the fabric or mat is fully impregnated with the thermoplastic polymer. During at least a portion of the process, humidity in the vicinity of the coated fabric or mat is maintained at substantially zero.

Permeable reactive barrier

A permeable reactive barrier having two or more layers of a geotextile fabric inoculated with a bioremediation microbe is provided. The permeable reactive barrier further includes two or more layers of coarse-grained geological material separating the two or more layers of geotextile fabric such that any pair of adjacent layers of geotextile fabric is separated by a layer of coarse-grained geological material. The permeable reactive barrier includes a perforated metal casing surrounding and containing the layers of coarse-grained geological materials and geotextile fabric.
