“…as compared to traditional synthetic fibers [9][10][11] . Perhaps the most attractive characteristic of lignocellulosic natural fibers is the clear positive environmental impact which arises from the fact that these fibers are renewable and can be easily eliminated at the end of their life cycle [12][13][14][15] . Therefore, these natural fibers constitute an interesting alternative to traditional synthetic fibers in composite materials.…”

A study on physical and chemical properties along with mechanical characterization of Hibiscus Sabdariffa fiber-reinforced Phenol-Formaldehyde resin matrix based polymer composites have been reported. Effect of fiber dimension on mechanical properties was evaluated. The interfacial bonding between Hibiscus Sabdariffa fiber and polymer matrix has been found to affect the properties of polymer matrix. It has been observed that particle reinforced polymer composites exhibit better mechanical properties as compared to short and long fiber reinforced polymeric composites. These composites were further subjected to evaluation of morphological, thermal, physical (swelling and moisture absorption) and chemical properties.

“…Kenaf fibers have been combed using laboratory Carding Machine‐337A, (MESDAN, Italy), then the fibers were formed into mat (20 × 20 cm 2 ) in a deckle box by the procedure reported earlier13 and dried in an oven at 105°C for 24 h. After that, mats were passed through needle punch Testing Machine model (SNP‐50), Shoou Shyng Machinery Co. with speed 200 strokes/min. Finally, the needle punched mats were pressed using hot press Gotech Testing Machine Inc model GT‐7014‐100 (2 min, 500 kg/cm 2 , 100°C) and the thickness of the mats were controlled to ∼ 1 mm.…”

“…This process employs ultraviolet radiation to cure the composites. In view of the advantages of ultraviolet curing system and the success of the photo‐fabrication of polymer matrix composites by the use of ultraviolet radiation,13 attempts have been made to apply the radiation curing technology for the production of bio‐fiber composites. Based on the above advantages and the success of the photo‐fabrication of polymer matrix composites, the work described in this article involved the production of composites with unsaturated polyester as matrix reinforced with kenaf fibers with the employment of ultraviolet radiation to cure the polymers matrix.…”

New bio-fiber composites (UPRC) cured by ultraviolet radiation were produced using kenaf fiber as reinforcing agent and unsaturated polyester resins as matrix in the presence of styrene and IRGACURE 1800 as photoinitiator. Unsaturated polyester resins based on palm oil were prepared from various ratios of monoglyceride (MG)/maleic anhydride (MA) by the interaction of the corresponding MG monomer, with different equivalents of MA, in the presence of 2-methylimidazole as catalyst. The various characteristics of the obtained bio-fiber composites, including mechanical, gel content, water absorption and thickness swelling test, thermal analysis, were determined and the data were discussed. Bio-fiber composite with MG: MA ratio (1 : 4 eq./eq.) showed better mechanical properties (tensile, flexural, and impact strength) than other formulations. Gel content increased as the amount of MA was increased up to the MG: MA ratio was 1 : 4 (eq./ eq.) then slightly decreased at the higher ratio formulation. Bio-fiber composite (UPRC c ) was considered the best prepared bio-fiber composite which contained higher degree double bond, cross-linking and thermal stability. Moreover, morphological study of selected examples of the formed bio-fiber composites was also carried out and showed the evidence of the enhancement of the compatibility between fiber and polymer matrix.

In this study, biofiber composites cured by ultra-violet, were produced using pulp made from empty fruit bunch (EFB) as the reinforcing agent and unsaturated polyester as the matrix. The conversion of EFB fibers into pulp was carried out using organosolv pulping process. The EFB pulp was then chemically treated with glycidyl methacrylate (GMA) to different percentage of weight percent gain and the composites were made with different percentages of pulp loading. Results showed that the Kappa number of EFB decreased as the NaOH concentration in organosolv pulping increased. Composites which were made from GMA-treated EFB showed better mechanical properties (tensile, flexural, and impact strength) than those of the unmodified. Fourier transform infrared spectroscopy showed peaks that proved the occurrence of grafting between GMA and OH from EFB pulp. Scanning electron microscope analysis showed the evidence of the enhancement of the compatibility between EFB and matrix.
