Physico-chemical and mechanical characterization of Cissus dinklagei fibers for the development of sustainable composite materials in construction
摘要
The aim of this research is to examine in depth the suitability of new cellulose fibres from a Cissus dinklagei liana as a potential reinforcement for polymer composites for use in construction. This article deals with the morphological, physical and mechanical properties of the fibres. The untreated and alkali-treated fibres were characterised at a time interval of T (30, 60, 90, 120, 210) minutes using scanning electron microscopy (SEM), optical microscopy and X-ray diffraction (XRD) and a tensile test to assess mechanical behaviour, and the chemical composition was determined using the TAPPI T 11 M 45 (1992) and ASTM (1972) standards. For the fibre treated for ninety minutes (T90), a Young's modulus E (5.06 ± 48) GPa was achieved. Micrographic analysis of the fibre revealed a honeycomb structure.
