“…The flexural properties of untreated and treated sisal/PLA composites at 20% fiber loading considered in this study was higher than that of untreated sisal/ PLA, MPS-g-PLA and PLA-co-PGMA treated sisal/ PLA composites at 30% fiber loading presented by Li et al 9 The flexural strength of untreated and treated Sisal/PLA composites at 20% fiber loading was also higher than that of PLA/Ramie and PLA/Jute composites at 30% fiber loading presented by Tao et al 4 and Senawi et al 34 The flexural strength was also higher than that of KDC filled PLA composite at 20% KDC loading presented in Syafinaz et al 35 Impact properties Figure 7 shows the variation of impact strength for various types of composites as a function of weight percentage of fibers and chemical treatment used on the fiber. The impact strength of untreated sisal/PLA composite was increased with fiber loading which is 123% higher compared with that of plain PLA.…”

The natural fiber reinforced biodegradable polymer composites were prepared with short sisal fiber as reinforcement in poly lactic acid (PLA) matrix. The sisal fiber is treated with 10% NaOH followed by H 2 O 2 . The composites were prepared with untreated and treated short sisal fibers at different weight proportions up to 25% in PLA matrix and investigated for mechanical and degradation properties. The results showed that the composite with treated fiber at 20% fiber loading has shown 30% and 8% higher tensile strength than neat PLA and untreated sisal/PLA composite, respectively. The flexural strength of treated sisal fiber composite at same weight fraction was 17% higher than that of plain PLA. The impact strength of composite with untreated fibers at 25% fiber loading was 107% high compared to that of neat PLA whereas the impact strength of treated sisal composite was reduced with increased fiber loading. The water absorption was high for untreated sisal/PLA composite compared to all other composites in the present study. Untreated sisal/PLA composite has high thermal degradation temperature compared to composite with treated fibers but lower than that of pure PLA. The enzymatic environment has increased the rate of degradation of composites. Surface morphology of tensile fractured and soil degraded surfaces of the composites were observed using scanning electron microscopy.

“…However, it is evident from the results that PLA/bleached fiber composites show significant improvement in tensile strength compared to the PLA/untreated fiber composites. According to Senawi et al [ 17 ] treatment of fiber improves biocomposites properties by increasing wettability and interfacial bond strength with the matrix, explaining the enhancement in strength. On the other hand, it was observed from the tensile strength result that the addition of 0.5 wt.…”

“…The results also demonstrate an improvement in impact strength for bleached fiber composites compared to the untreated fiber composite. The improvement is likely due to the enhancement of fiber-matrix interaction which provides higher resistance to crack propagation [ 17 ].…”

In this work, biodegradable composites from poly(lactic acid) (PLA) and oil palm empty fruit bunch (OPEFB) fiber were prepared by melt blending method. Prior to mixing, the fiber was modified through bleaching treatment using hydrogen peroxide. Bleached fiber composite showed an improvement in mechanical properties as compared to untreated fiber composite due to the enhanced fiber/matrix interfacial adhesion. Interestingly, fiber bleaching treatment also improved the physical appearance of the composite. The study was extended by blending the composites with commercially available masterbatch colorant.

“…Thus, the treatment of EFB fibers is essential to overcome the unfavorable properties of producing fibers with matrix-compatible properties, especially in composite production. Numerous research and studies have been conducted in relation to the treatment of EFB fibers [6][7][8][9][10][11]. In addition, several types of chemicals, such as silane, succinic anhydride, acrylic acid, formic acid, and phosphoric acid, are also used for the treatment of EFB fibers [9][10][11][12][13].…”

Empty Fruit Bunches (EFB) are abundance residues from palm oil plantation was recognised as a potential material for manufacture such as particleboard and medium density fibreboard (MDF). The objective of this study is to identify and assess the potential effects of chemical treatment and concentration on the mechanical and bonding properties of MDF from EFB oil palm fibres. The EFB fibres were treated at 0.2, 0.4, 0.6 and 0.8% of sodium hydroxide (NaOH) and acetic acid (CH?COOH), and the fibres were used in the MDF production. Mechanical test included modulus of rupture (MOR), modulus of elasticity (MOE) and internal bonding (IB) were conducted. Between the chemical treatment and the concentration, the chemical types used had a more prominent effect compared to the concentration. This study also shows that both treatments resulted in different MDF performance, where acid acetic fibre produced better bending and bonding properties. The optimum condition was 0.4% for NaOH and 0.6% for CH?COOH to produced panels with good strength and better dimensional stability. Such sample for 0.4% NaOH had 17.9 MPa, 1297 MPa and 0.48 MPa, and for 0.6% CH?COOH had 22.1 MPa, 1641 MPa and 0.56 MPa, for MOR, MOE and IB, respectively.
