An Iranian parts manufacturing company, using a new Iranian nanocomposite, has succeeded in designing and manufacturing a car bumper in order to improve its properties such as strength and impact.
Mehrkhah Industrial Co., which is active in the field of polymer parts manufacturing, is one of the active companies in the field of plastic injection and assembly of various types of polymer parts in Iran, which has recently used nanotechnology in the production of automotive polymer parts.
The company uses nanoparticle-reinforced polypropylene developed by Shamim Polymer Kosar to build a car bumper. The focus of this demand is to replace conventional bumpers with nanoparticles containing shields to improve the mechanical and coloring properties of the car bumper and ultimately to deliver a higher quality and robust product.
Shamim Polymer Company has developed a nanocomposite that can be used in bumpers, shields, bumper and shield’s components with polymer replacement components in other industries. Due to the presence of the nano-reinforcers, mechanical properties such as notched impact resistance have increased by 10-15% while the colourability of the polymer components has improved dramatically.
Polypropylene (PP) is used in the automotive industry because of its low cost, excellent mechanical properties and excellent moldability in the manufacturing of more than 50% of the plastics materials used. Polypropylene compounds are used in various parts of the vehicles such as bumpers, dashboards and doors.
The combination of nanoparticles with polymer matrix has received a great deal of attention in the application of polypropylene compounds in the automotive industry. This is due to the possibility of using less amounts of nanoparticles (as fillers) with increasing mechanical properties such as impact and strength.
According to data released by Shamim Polymer Kosar, adding nanoparticles as fillers in the polymer matrix results in improved mechanical strength and impact resistance.
The mechanical properties of this product have been improved by the single-axis tensile test according to ASTM 638: 14, so that the use of nanomaterials results in a 3 and 68% increase in yield strength and elongation at break point, respectively. There is also a 10 and 50% decrease in fracture strength and elongation at the yield point, respectively. According to the Charpy Impact Test ASTM D6110: 10, a 5% increase in end-product impact resistance occurs.
This joint collaboration can lead to the improvement of the Irnian automotive industry and the improvement of components used in domestic cars.
