Abstract
Enclosure parts for portable information handling systems may be made by heat pressing material layers together. The material layers may include outer fiber-reinforced thermoplastic layers and a core thermoplastic layer comprising a plurality of thermoplastic film layers. The core thermoplastic layer may be die cut to create voids that reduce weight of the enclosure part. A finishing layer may be added, along with attachment features.
