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.

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.

The current development of new potential fibers is widening the areas of application. One of the current potential fibers developed is pineapple leaf fiber (PALF). PALF have been widely used as a raw material for pulp and paper making industry in Malaysia recently. Due to its enhanced properties, PALF now is commercialized as an alternative textile fiber. PALF is one of the high textile grade fibers which are commonly extracted by decorticator machine. PALF is silky, fine and textile grade. Hence, it has been widely used to make apparel. Apart from being used as an alternative fiber for home textile and apparel, PALF meet the basic requirement to be used as technical fibers. This paper presented the possibility of PALF utilization as technical fibers in rope making. PALF have similarity properties with others natural rope fibers and its can be spun into rope yarn. Instead of having a good strength, PALF also have a reasonable length as well as can be pliable. All of these are the main principle of rope making fibers. As PALF have meet this entire requirement, it can be said that its have huge potential to be used as rope making fibers.

Recently, most of the industries are looking towards to incorporate sustainable, renewable, eco- friendly and affordable raw materials and production process. To achieve this goal, engineers and technologist are working on biocomposite material. The primary reason behind the selection of natural fiber based material in the automobile, construction, and aerospace industry is its low cost, lightweight, high specific strength and modulus, biodegradability, and friendly processing. Inspite of all beneficial features, one of the main barriers to their utilization in all mentioned sectors is thermal degradability. Natural fibers can be subjected to thermal degradation during composite processing and their application in the high-temperature field. So it is practically significant to understand the thermal decomposition of lignocellulosic fibers and to modify it for the purpose of high-temperature stability. In this work, alkaline treatment of varying concentrations (2%, 4%, 6%, 8%, and 10 wt %) was used to study the effect of alkaline treatment on thermal stability of pineapple leaf fibers. The thermal behavior of untreated and alkali treated pineapple leaf fiber was examined by using a thermal gravimetric analysis instrument (TGA). The results show that 4 wt% NaOH treated pineapple leaf fiber have maximum thermal stability. The decomposition of untreated and treated PALF was a two-stage process attributed to the thermal decomposition of hemicellulose, cellulose, and lignin. The results also showed that the temperature of initial degradation 251 0C increased to 285 0C after 4% alkaline treatment due to partial removal of hemicellulose and lignin.
