The effect of compression temperature and time on 2D woven kenaf fiber reinforced acrylonitrile-butadiene-styrene (ABS)

A natural fibre-based composite from woven kenaf was fabricated using hydraulic hot press machine. Plain woven kenaf fabrics were prepared and used as reinforced material with ABS sheet followed by hot press. Woven fabric was treated using sodium hydroxide and being compare with untreated fabric. The effect of the processing temperature and time towards tensile properties of the composite were investigated. Tensile test was carried out to measure the strength of the composite towards the effect of processing temperature and time. The surface morphology of the composite was studied with Scanning Electron Microscope (SEM) and Optical Microscopic. The result shows that woven Kenaf degrade in strength when expose with high temperature and long exposure to the heat. The permeability of woven Kenaf plain fabric does not indicate a good penetration as observed by microscopy

Improvement of mechanical properties of polycaprolactone (PCL) by addition of nano-montmorillonite (MMT) and hydroxyapatite (HA)

F or many years, researcher have focused on developing a medical part of human body from polym er as to replace metal. This report described the mechanical characteristic of biodegradable Polycaprolactone (PCL) blend with nano - Montmorillonite ( MMT ) and Hydroxyapatite ( HA ) . The amount of nano - MMT is varies from 2 to 4 by weight % meanwhile the amoun t of HA is fixed to 10 by weight percentage (wt %) . The addition of nano - MMT and HA filler is to tune and indirectly improve the mechanical properties of PCL. These are prove n by carrying out the tensile, and also flexural test for samples which is injecte d from injection molding m achine. Both the tensile and flexural test are conducted using Shimadzu AG - I Unversal Testing Machine with 10 k N capacity. From the analysis it is found that overall PCL/ MMT/ HA composites gives better result in both tensile and fle xural analysis compare to PCL/MMT composite. PCL/MMT/HA composite with 2 wt% of MMT and 10 wt% of HA have indicated the highest tensile modulu s, meanwhile PCL/MMT/HA composite with 4 wt% MMT and 10 wt% HA have plot ted the highest flexural strength and modu lus value
