“…The de‐bonding between fiber and matrix was visibly indicated in UTMFC. This was due to the presence of hemicellulose, lignin, wax, and moisture contents present in the fiber . In case of UTMFC, it can be seen that there was a poor adhesion between the fiber and matrix.…”

In this research work, the untreated and various concentrations of alkali treated continuous mulberry fibers were used as reinforcement in polyester matrix and its static and dynamic mechanical properties were investigated. The composites were fabricated using untreated, 5%, 10%, and 15% alkali treated mulberry fibers (ATMF) reinforced in polyester resin by compression molding technique. The result showed that the 10% alkali treated mulberry fiber composite (ATMFC) considerable increase in tensile, flexural, and impact properties compared to untreated, 5% and 15% alkali treated mulberry fiber composites. The 15% alkali treated mulberry fiber composite showed decrease in water absorption property. The fractured surface morphology of composite samples was examined by Scanning Electron Microscopy (SEM). The Dynamic Mechanical Analysis (DMA) shows that the 10% alkali treated mulberry fiber composite enhanced storage and loss modulus compared to untreated, 5% and 15% alkali treated mulberry fiber composites. The weight loss of untreated, 5%, 10%, and 15% alkali treated composites were studied under varying temperature by Thermo Gravimetric Analysis (TGA) and Differential Thermo Gravimetric analysis (DTG).

The present investigation aimed to understand the physicochemical properties of the new cellulosic fiber extracted from the bark of Silybum marianum (SM), in view of using it as a potential reinforcement for polymer composites. The morphological and anatomy, physical, thermal and mechanical properties of fibers were firstly discussed in this paper. The Silybum marianum fibers (SMF) were characterized by scanning electron microscopy, Fourier transform infrared, thermogravimetric analysis (TGA), optical microscope, X-ray diffraction (XRD), and single fiber tensile test. The average Young’s modulus and the breaking stress data presented by the fibers are 15.97 GPa and 201.16 MPa, respectively. XRD reveals the presence of cellulose with a crystallinity index of 45%. Thermal stability (250°C) and maximum degradation temperature (357.72°C) of the SMF are established by the thermogravimetric analysis. An analysis of the mechanical properties was carried out on a population of 35 samples using Weibull statistics with two and three parameters.

“…This is because the N–H structure is still retained after modification and is abundant in the protein skeleton. However, the increased signal of symmetric stretching vibration of C–H at 2970 cm −1 and 2878 cm −1 and the appearance of C–H unsymmetrical stretching vibration at 2357 cm −1 [ 35 ], C–O–C stretching band at 1069 cm −1 [ 36 ], and the out-plane deformation vibration of C–H at 892 cm −1 indicate the successfully grafting of the double carbon bonds with PEG chain to the elastin.
