“…However, with increasing fiber content, an increase in sound absorption coefficient can be observed, especially at higher concentrations. This behavior was found in the other works of composites reinforced with natural fiber [57,61]. The composites with 30 wt% in fiber was characterized by an acoustic absorption improvement of about 40%.…”

The aim of the present work pointed out the introduction of natural alkalised alpha fibres as reinforcement in the preparation of partially biodegradable green insulation material composite. Thermal conductivity, mechanical properties and acoustical performances of composites were investigated as a function of fibre content. We found that 10% of alkali solution improve the hydrophobic character, mechanical and interfacial properties of the fibers. Composites made of alfa fibers-polyurethane resin has exhibited good mechanical and acoustical properties. At 20% of reinforcement the Young modulus and tensile stress increased by 48.14% and 74.12%, respectively.

“…When the composites are thoroughly degraded, the residual mass of TBFC is found to be higher than that of UBFC, which could be expected that the thermal stability appears to be improved by the surface modification, because the remaining celluloses of fibers will occupy crystalline structure after the treatment . Another factor that contributes to the higher thermal stability of composites is the enhanced interfacial interaction, generating additional intermolecular bonding between fiber and matrix …”

Biodegradable composites reinforced with natural fibers are emerging as advanced materials in structural applications. In this work, green biocomposites are fabricated using hot pressing molding technique, polylactic acid selected as a matrix. The samples are prepared with different fiber volume fractions (30%, 40%, and 50%). Tensile tests are conducted on the specimens to investigate the composite mechanical behavior, and the influences of fiber content on the morphological and thermomechanical properties are evaluated using scanning electron microscopy, differential scanning calorimetry, and thermogravimetric analysis. There are higher tensile modulus and lower elongation at break for composites with increasing fiber content, respectively. Much variation in the tensile strength is observed when the fiber content is varied, which could be attributed to fiber agglomerations that affect the dispersion of fibers in the matrix, as evidenced by fracture surfaces. Thermal tests demonstrate that the increment of fiber content enhances the glass transition temperature and crystallization temperature of composites. Besides, a comparative analysis of the composites is performed, and the properties of the treated fiber composites are found to be improved compared to those from untreated fibers. Detailed analysis confirms the possibility of the addition of bamboo fibers to a biodegradable matrix for a specific application. V C 2017Wiley Periodicals, Inc. J. Appl. Polym.

“…Since many pectin and waxy materials cover the fiber surface, the hydroxyl groups are hindered from reacting with polymer matrix. This incompatibility can adversely affect the adhesion of the fiber with hydrophobic matrix materials, with negative consequences such as debonding in the resulting composites . In particular, research work indicates that weak interfacial bonding always weakens the reinforcing action of the fiber due to ineffective load transfer from the matrix to neighboring fibers .…”

The aim of this study is to perform an intensive investigation of the influence of alkali concentrations on the microstructure and thermomechanical properties of bamboo fibers. The fibers were alkalized with 1, 4, and 7 wt% NaOH solution at room temperature for 1 h, respectively, and then they were examined by using scanning electron microscopy, Fourier transform infrared spectroscopy, thermogravimetric analysis, X‐ray diffraction, and tensile tests. The changes in morphology and chemical composition demonstrate that hemicellulose and lignin are likely removed by the alkalization with high concentration of NaOH. Compared with untreated fibers, there is an improvement in the average tensile strength of the fibers with the use of alkali treatment at 4 wt% concentration, which can be attributed to the formation of an effective contact area available for superior bonding with the matrix after treatment, whereas higher concentration used in the treatment induces a decrease of tensile strength. The analysis indicates that the elimination of binding materials with alkali treatment by higher concentration leading to partial removal of cellulose may be responsible for such changes. It is further verified by thermogravimetric analysis and X‐ray diffraction that the increase of alkali concentration helps facilitate an improvement of thermal stability. The overall results suggest that an appropriate alkali treatment is a key technology for enhancing the properties of natural fibers. POLYM.
