Development of Technology for Producing Light-weight, Jute Fibre and/or Jute Stick and/or Wool based Reinforced Composite Components for Automotive Sector
In Short:
There is enough attention paid in the western world to promote use of Flax, Hemp, Sisal, Cotton & wood as reinforcement fibers, however no such promotion activity is in pipeline to promote use of jute as reinforcement fiber for making auto parts. Since India is main producer of Jute fiber, IJIRA has been investing aggressively on development activity for use of jute-based composites in making auto parts may also generate interest of OEMs in jute-composite based auto parts.
Of late, in India Tier-I sector has been showing keen interest in development of non functional auto parts such as parcel shelf, wheel arch etc where natural fibres may be incorporated. A new technology has been developed as per expectations of OEM which has now gone to serial production for parcel shelf. It is lighter and cheaper than products. The produced pacel shelf is a it may open a flood gate for use of jute in auto components. This may be the first attempt of its kind in India.
In Detail:
This project has utilized jute waste and/or other wastes produced in India such as jute stick, jute caddies and wool for partial replacement of plastics in the auto sector. Better utilization of jute caddies and/or jute sticks through innovative technologies, has only added to the development of green composites but also added value to the production chain of jute goods and better remuneration to Jute farmers.
Through this project, an attempt has been made to develop a novel technology based on the local agro waste which may later on attract global OEMs. The project is likely to generate business based on Environmental Social Governance. Besides reducing the carbon footprint, this project is also leading to farmers benefit, employment generation and promotion of “Make-in-India” concept of the Government of India.
Polymer matrix has been kneaded with appropriate form of jute waste/ stick in various proportions under hot condition to melt and screw-fed into calendaring rollers to produce continuous sheet. The process parameters such as blending ratio, kneading temperature, mixing time, additive application percentage, mode of addition, and sequence of addition has been optimized prior to molding for different variations of sheets produced in the first step. These sheets will then be preheated and compression molded to prepare automotive part. The molding parameters such as ease of molding, preheating temperature, and pressure of compression have also may optimized. Parcel shelves of a branded car has been manufactured using this method.
Performance and field testing of a developed product has been planned by the industry partner for final product evaluation. Based on evaluation result, the master-batch has been finalized by determining optimum ratio as well as process condition. A few of following performance tests has been carried out for selected automotive parts based on discussion with an OEM.
Commercialization Status:
This innovation has already been commercialized through technology transfer to two manufacturing companies,. JCI has recently purchased about 50 MT of IJIRA-SUBHRA under Jute-I-CARE scheme of Ministry of Textiles.
Patents:
The patent for this technology is under process (Patent Application No. 201831038353). Also, one paper has been published in journal of Natural Fibres in December 2021 (DOI: 10.1080/15440478.2021.2009393).
