CHARACTERIZATION OF COMPOSITE CONTAINING LDPE ( LOW DENSITY POLY ETHYLENE) AND MODIFIED PINEAPPLE LEAF FIBER. Pineapple leaf fiber could be used as a reinforcing material in natural fiber composites production with a synthetic polymer matrix. The typical problem in this process was the weak bond between the fiber component and the matrix. This study aimed to improve the bonds strength between pineapple leaf fibers and the polymer matrix of LDPE (Low Density Poly Ethylene) by modifying pineapple leaf fibers. The modification of pineapple leaf fibers was carried out through an enzymatic process using the xylanase enzyme. A modified fiber was then used as a fiber component in the composite using a commercial LDPE plastic matrix. Composites were made by the sandwich method using a hotpress machine at a temperature of 130 °C for 10 minutes. The evaluation of the composites were carried out by testing the tensile strength properties using the Tensolab tool and thermal properties using the TGA (Thermal Gravimetry Analysis) instrument. The results of the mechanical properties test of the composite showed the modified pineapple leaf fiber-based composite had a better tensile strength (34.3 MPa) than the untreated pineapple leaf fiber-based composite (30.2 MPa). The results of the thermal properties test showed the decreasing of the mass occurred at temperature of 300-350 °C due to degradation of the fiber,and it completely degraded at temperature of 450 °C.

Utilization of natural fiber waste, especially pineapple dau fiber, is a major concern and continues to be developed to utilize and optimize plantation waste as a material that is more environmentally friendly, energy efficient and inexpensive. The purpose of this study was to determine the effect of alkaline treatment on the mechanical properties of pineapple leaf fiber composite material as an appropriate alternative material. The method in this research is the experimental method, where the research was carried out by giving variations in the percentage of alkaline 10% and 20%. The results of the research on the composite material of pineapple leaf fiber using tensile testing showed that giving alkaline treatment with a percentage of 20% made the fiber stronger but brittle. In addition, the orientation direction and immersion time also affect the tensile strength of the fibers. Pemanfaatan limbah serat alam khususnya serat dau nanas menjadi bahan alternatif menjadi perhatian utama serta terus dikembangkan guna memanfaatkan dan mengoptimalkan limbah perkebunan sebagai bahan material yang lebih ramah lingkungan, hemat energi, dan murah. Tujuan penelitian ini untuk mengetahui pengaruh perlakuan alkali terhadap sifat mekanik material komposit serat daun nanas sebagai bahan alternatif tepat guna. Metode dalam penelitian ini yaitu metode eksperimen, dimana penelitian dilakukan dengan pemberian variasi persentase alkali 10% dan 20%. Hasil penelitian material komposit serat daun nanas dengan menggunakan pengujian tarik menunjukkan bahwa pemberian perlakuan alkali dengan persentase 20% membuat serat menjadi lebih kuat namun bersifat getas. Selain itu, arah orientasi dan waktu perendaman juga mempengaruhi kekuatan tarik serat.

Research has been conducted on the manufacture and characterization of pineapple leaf fiber composites – polypropylene matrix. Samples with comparison of pineapple leaf fiber composition: polypropylene matrix by 0 %: 100%, 5%: 95%, 10%:90%, 15%:85%, 20%;80%, and 25%:75%. The manufacture of SDN-PP composites, i.e. fiber soaked with NaOH 5% for 2 hours and then rinsed with clean water and dried, then weighed. Polypropylene and MAPP are effluxed with xylen solvent using a reflux device over a hot plate with a temperature of 17oC until melted. The polypropylene that has been diflux weighed in mass and pineapple leaf fibers are placed into a mold then pressed with a hot press at a temperature of 150oC for 30 minutes. The purpose of the study was to find out the physical and mechanical properties of pineapple leaf-matrix polypropylene fibers. Density values 0.75 g/cm3 to 0.9 g/cm3, water absorption values 0.54% to 14.38%, strong compressive values 25.09 MPa to 49.58 MPa, and strong values impact 9.74 J/mm2 to 34.18 J/mm2.  Pineapple leaf fiber composite – the resulting polypropylene matrix can be categorized as a high-crust fiberboard (HF) and applied as a decorative board in accordance with the fiberboard standards set out in SNI 01-4449-2006.

Evidence-based research had shown that elevated alkali treatment of pineapple leaf fiber (PALF) compromised the mechanical properties of the fiber. In this work, PALF was subjected to differential alkali concentrations: 1, 3, 6, and 9% wt/wt to study the influence on the mechanical and crystal properties of the fiber. The crystalline and mechanical properties of untreated and alkali-treated PALF samples were investigated by X-ray diffractometry (XRD), Fourier transform infrared spectroscopy (FTIR), and tensile testing analysis. The XRD results indicated that crystal properties of the fibers were modified with 6% wt/wt alkali-treated PALF recording the highest crystallinity and crystallite size of 76% and 24 nm, respectively. The FTIR spectra suggested that all alkali-treated PALF samples underwent lignin and hemicellulose removal to varying degrees. An increase in the crystalline properties improved the mechanical properties of the PALF treated with alkali at 6% wt/wt, which has the highest tensile strength (1620 MPa). Although the elevated alkali treatment resulted in decreased mechanical properties of PALF, crystallinity generally increased. The findings revealed that the mechanical properties of PALF not only improve with increasing crystallinity and crystallite size, but are also dependent on the intermediate bond between adjacent cellulose chains.

Natural fibers have become an important issue in the development of fiber reinforced polymer (FRP) composite to resolve the current ecological and environmental problems. Among the many types of natural fibers that are available, pineapple leaf fiber (PLF) was selected as the natural fiber used in this study due to comparatively better mechanical properties, ease of availability and low cost. In this work, the effects of pineapple leaf fiber (PLF) loading on the properties of PLF/polypropylene (PP) composites was studied. The sample of composites was fabricated with five different fiber loading of PLF (30, 40, 50, 60 and 70 wt.%). An alkaline treatment was conducted to enhance the PLF properties. The fabrication was made by compression molding technique with random orientation of PLF. From the experimental study, the results revealed that the voids percentage and interfacial bonding between the PLF and PP affected the mechanical properties of the PLF/PP composite. Based on the results of tensile stress, hardness and density, it can be concluded that the PLF/PP composite with the composition ratio of 30/70 wt.% has shown the best mechanical properties compared to other composition ratios (40/60, 50/50, 60/40 and 70/30 wt.%), which are 16.71 MPa, 62.83 Shore-D and 0.93 g/cm³ respectively.
