LOCALIZED REINFORCEMENT PANELS
20210016525 · 2021-01-21 ·

Disclosed herein is a reinforced panel. The reinforced panel is produced by a process that comprises applying a reinforcing fiber material, comprising a first polymeric material, to only a portion of a panel sheet, comprising a second polymeric material. The process also comprises, after applying the reinforcing fiber material to the panel sheet, thermoforming both the second polymeric material of the panel sheet and the first polymeric material of the reinforcing fiber material. The thermoforming integrally couples the panel sheet with the reinforcing fiber material to produce the reinforced panel by fusion bonding the first polymeric material with the second polymeric material. The reinforced panel includes one or more reinforced portions, defined by the reinforcing fiber material, and one or more non-reinforced portions, defined between the reinforcing fiber material.
