Laminated composites are subject to delamination. This study aims to address this drawback and obtain structurally stable, lightweight, thin laminated composites through a novel manufacturing method that involves blending thermoplastic polyurethane (TPU), low-melting polyester (LMPET), and Kevlar. Nonwoven LMPET/Kevlar fabrics are first processed through a nonwoven technique and then combined twice with TPU sheets through the sheet extrusion method. The mechanical properties, thermal behavior, and combustion resistance of the laminated TPU/LMPET/Kevlar composites are then evaluated. Results show that LMPET fibers strengthen adhesion between TPU and nonwoven laminates, and the addition of a small amount of TPU increases the peeling strength of the laminated TPU/LMPET/Kevlar composites by 1.9-fold.
