Study on the Hardness and Wear Behavior of Eco-Friendly Poly(butylenes Succinate)-Based Bamboo Carbon Composites

Eco-friendly poly(butylenes succinate) (PBS)/bamboo carbon lubricant composites were designed and prepared by hot pressing. The hardness and wear properties of the designed PBS composites were studied. The results showed that the hardness of PBS composite containing 50% of the bamboo carbon lubricant increased by more than 150%. The composite material with 50% bamboo carbon lubricant had the lowest wear rate, which was up to 72% lower than that of pure PBS. The wear of neat PBS was harsh with severe cut and even partly melted points appearing on the worn surface. The wear modes of PBS bamboo carbon composite were abrasive wear and fatigue wear. While the worn surface of PBS bamboo carbon lubricant composite was with slight exfoliation, its wear mode was slight adhesive wear. It is concluded that the addition of bamboo carbon lubricant can broaden the application range of eco-friendly polymer of PBS in the engineering field of anti-wear requirements.
