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.

Polymeric Waste

The objective of this work is to recycle the printed circuit boards of electronic equipment discarded and mix them with polypropylene (PP) to produce a new composite. Six types of mix of discarded printed circuit boards were analyzed: new boards with and without copper, used boards without components and with and without copper, used boards without components and without copper, used boards with copper track, used boards with copper track and burned and used boards with components. Boards were disintegrated and employed as reinforcement with polypropylene matrix (5% m/m). Specimens were produced for flexural and impact tests. Results showed that specimen’s properties depend on the mix composition. In all of the cases, pure PP properties were enhanced when it was replaced by 5% of waste materials discard.

Bagasse Fiber

Polymer composites reinforced with natural fiber that were obtained as industrial wastes, are of particular interest due to both the environmental benefits and economical advantages. In the present work sugarcane bagasse fibers, obtained as a waste from sugar and ethanol production, were incorporated in an amount of 25wt% into a polypropylene matrix. These fibers were previously alkali treated with NaOH to improve their adherence to the composite matrix. Thermal analyses were conducted in both types of composites, with untreated fibers and with alkali treated fiber. The result indicated that the alkali treatment improves the compatibility between the bagasse fiber and the polypropylene matrix, which then provides more thermal resistance.
