Quasi static indentation of fully polypropylene sandwich panel

This research investigates the quasi-static penetration behavior of thermoplastic sandwich panels with polypropylene skins and cores, fabricated using ultrasonic welding and polypropylene pins. Quasi-static penetration tests were performed on panels with pin spacing’s of ۸ cm and ۵.۲ cm. Results showed that reducing pin spacing enhanced penetration resistance, strength, and load distribution. With its high mechanical strength and recyclability, polypropylene ensures both mechanical optimization and environmental sustainability. The findings highlight ultrasonic-welded thermoplastic panels as a cost-effective, eco-friendly solution for designing strong and sustainable structures in industries requiring efficient, lightweight materials with reduced production time and cost. These results pave the way for broader industrial applications.
