Study On Impact Resistance Performance Of Arenga Pinnata Fibre Reinforced Composite

  1. 1. Study on Impact Resistance Performance of Arenga Pinnata Fibre Reinforced Composite By: Ahmad Mujahid Ahmad Zaidi Advance Textile Training Centre (ADTEC) Faculty of Mechanical and Manufacturing Engineering Universiti Tun Hussein Onn Malaysia
  2. 2. Study on Impact Resistance Performance of Arenga Pinnata Fibre Reinforced Composite What is Composite? Composite materials (or composites for short) are engineered materials made from two or more constituent materials with significantly different physical or chemical properties which remain separate and distinct on a macroscopic level within the finished structure. Advantages: Lightweight, Good materials properties, etc. Figure 1: Applications of composite materials.

  7. 7. Study on Impact Resistance Performance of Arenga Pinnata Fibre Reinforced Composite What are Important Ingredients in Composite? Two IMPORTANT INGREDIENTS, i.e. filler (fibre reinforcement) and matrix binder. Types of FIBRE: qNatural : Cellulose Animal qSynthetic : Oil based fibre.
  8. 8. Study on Impact Resistance Performance of Arenga Pinnata Fibre Reinforced Composite Why is Natural Fibre? Nature continues to provide mankind generously with all kinds of rich resources in plentiful abundance, such as natural fibres from a vast number of plants. However, since the last decade, a great deal of emphasis has been focused on the development and application of natural fibre as reinforcement in composite materials in many industries. This is due to the natural fibres composites are undergoing a high tech revolution and are replacing conventional composites in high performance applications due to their advantages over conventional reinforcements. For this reason natural fibres reinforced composite are applicable and need broader research programmes. Moreover, due to the relatively high cost of synthetic fibres such as glass, plastic, carbon and Kevlar used in fibre reinforced composites and the health hazards of asbestos fibres, it becomes necessary to explore natural fibres, e.g. cotton, sisal, jute, palm oil, paddy, ijok, etc. In addition, the main advantages of these fibres are their availability in large quantities in many countries, good thermal and acoustic insulating properties, better electrical resistance, higher resistance to fracture and impact absorption, low density, low cost and ease to manufacture.
  9. 9. Study on Impact Resistance Performance of Arenga Pinnata Fibre Reinforced Composite What is Arenga Pinnata? IJUK or scientific name is Arenga Pinnata is a type of PALM TREE native to tropical ASIA (inc. MALAYSIA). Medium size palm (growing up to 20m) and trunk covered by rough old leaf bases. In this research, the composite material is made by using IJUK fibre as reinforcement and epoxy resin as a binder.
