| Abstract Scope |
The development of new materials has led to the search for alternative, sustainable raw materials that aim to improve performance. These raw materials are low in weight, have good mechanical performance and are biodegradable. To this end, the aim is to investigate the thermal characteristics of Mucajá fiber. The fibers were analyzed using Fourier Transform Infrared Spectroscopy (FTIR), Thermogravimetry (TGA), Differential Scanning Calorimetry (DSC) and Scanning Electron Microscopy (SEM). The FTIR results showed the existence of functional groups characteristic of the elements cellulose, lignin and hemicellulose. TGA at 262 ºC showed greater thermal stability and total degradation at 700 ºC. DSC revealed an endothermic peak near 77.15 ºC, ∆H = 147 J and an exothermic peak at 54 J. SEM showed irregularities and pores along the longitudinal surface of the fiber. Mucajá fibers may have potential for application in various areas, especially in the field of making composite materials. |
