Development of Thermoplastic Composite Reinforced Ultra-High-Performance Concrete Panels for Impact Resistance

In order to improve flexural and impact performance, thin panels of steel fiber-reinforced ultra-high performance concrete (UHPC) were further reinforced with external layers continuous thermoplastic (CFRTP) composites. CFRTP sheets bonded 305 × 12 mm UHPC using two different techniques. First, unidirectional E-glass tapes polyethylene terephthalate glycol-modified (PETG) arranged in fused the through thermoforming. Second, fiber woven fabrics placed on panel faces by vacuum infusion a methyl methacrylate (MAA) polymer. Specimens cut into four 150 square for quasi-static low-velocity testing which loads applied at centers. Under loading, both types composite reinforcements led 150–180% increase peak load capacity toughness. Impact was measured terms residual deformation change specimen compliance, additions reduced 80% 95%, indicating an damage resistance. While reinforcement fabrication techniques provided added thermoforming method preferable due its simplicity fewer specialized tool requirements.
