Bending Performance of Carbonized Bamboo Scrimber and Fracture Morphology Analysis after Different Ageing Treatments

Abstract:

This paper described the influence of different ageing treatments on bending performance of carbonized bamboo scrimber according to three ageing standards (ASTM D1037, BS EN1087-1 and WCAMA). The modulus of elasticity (MOE) and modulus of rupture (MOR) were tested and the fracture morphology of the samples after mechanical test was also analyzed by SEM before and after ageing. The results showed that the average reduction rates of MOE and MOR were respectively 47.48% and 34.98%. In addition, SEM micrographs revealed that the fracture morphology of ASTM and BS EN presented smoother surfaces than WCAMA. The fracture surface of WCAMA was similar to Control but smoother in some parts. This was mainly due to the brittle rupture playing a dominating role in different degrees based on three ageing treatments. In conclusion, the brittleness of material after ageing was intensified leading to the decline of the bending performance.
