Thermoplastic composites with 45% by volume of fibres were prepared by using poly(lactic acid) as matrix and basalt woven fabrics as reinforcement. The effect on the laminate performance of a thermal repairing process after non perforating single or consecutive impact events was investigated. The first impact of a series was characterized by a lower value of the peak force, while the following impacts showed a higher peak and a stecper rise of the force, with a substantial superposition of all consecutive impact responses. The laminates showed some energy dissipation after the first impact at all energy levels, while successive impacts didn”t show energy dissipation until 8 J. The damaged laminates were then repaired at 100 °C and 175°C. Scanning laser Doppler vibrometry (SLVD) and microtomography (microCT) were used to assess the laminate damage. Both SLDV and microCT analyses confirmed that matrix continuity and woven fabric planarity were restored at the higher temperature. A second impact testing campaign on the same points demonstrated the complete recovery of the impact resistance after the thermal repairment at 175 °C.
