Investigation into the use of alkali treated screwpine (Pandanus Utilis) fibres as reinforcement in epoxy matrix

Better Wettability of Pandanus Utilis Alkaline Treated Fibres Tead to Higher Tensile Strengths of Composites.

“…As the length of the bre is increased, the tensile strength of the biocomposite decreases to a minimum value of 3.23 ± 1.37 MPa at 15mm chopped length. Although Deesoruth et al (2014) have determined that the critical length of 'Pandanus utilis' bre is L c = 2.64mm, the present ndings show that the tested lengths L between 2Lc (6 mm) and 6Lc (15 mm) of the treated bre lead to a reduction in the tensile strength of the composite. The same observation was made by Yang et al (2019).…”

“…The same observation was made by Yang et al (2019). [15,20] Fig 3 Tensile strength of the different composites produced using different ber length Takagi and Ichihara (2004) observed bre pull-out phenomenon when NaOH treated bamboo bres of 8 mm length or less was used in a resin, whereas bre fracture occurred when the bre length was 15 mm or more. These authors concluded that the bre critical length was about 12 mm whereas theoretically they calculated the critical length as being 30 mm.…”

“…[13] Research has also been conducted on the Pandanaceae species and their application in biocomposite. An optimum tensile strength of 17 MPa was obtained using 'Pandanus Fascicularis' in polyester composites while the potential application of 'Pandanus utilis' in epoxy composites as a substitution to glass bre was discussed by Deesoruth et al (2014) with a biocomposite having a compressive strength of 97.9 MPa for weight ratio of 10% of the optimum treated bre (5% w.t NaOH for 45min at 75°C). [14,15] In this study, an investigation was performed in order to evaluate the effect of the alkaline treatment on the wettability of 'Pandanus utilis' bre and the impact of this property on the tensile strength of the reinforced plastic composite produced by compression moulding.…”

Furthermore, in the same process, the relationship of the tensile strength of the reinforced biocomposite with the bre chopped length used for the biocomposite was studied and compared to the composite being produced industrially by a local company.…”

Fabrication and Characterization of Cellulose Microfibrils from Pandanus tectorius(Screw Pine) for Polymer Composite Application

“…The results showed the Young's modulus increased by about 30%, while the tensile strength and elongation at break for composites decreased with addition of MCC. In the work by Deesoruth et al [12] carry out investigation on an epoxy ABSTRACT Natural cellulose fiber was extracted from Pandanus tectorius (Screw pine) leaves using alkali and combined alkali-bleach treatment. Influence of extraction process parameters on the yield content and mechanical property was evaluated.…”
