Multilayer Shields Made From Natural Textiles

A multilayer shield is an efficient personal protection system against the threat of high-energy kinetic weapons. Generally, these multilayer shields consist of ceramic (SiC), composite (Kevlar / epoxy) and metal (Al).


Researcher of Universiti Putra Malaysia (UPM), Dr. Mohammad Jawaid, who is also a Specialist in Reinforced Hybrids and Materials from the Institute of Tropical Forestry and Forest Products, said replacing aramid fabrics with eco-natural and simple materials without compromising ballistic performance was an interesting research approach to multilayer shields.


Regarding the multilayer shield technology led by him himself, this technology called the Economic Techno Hard Body Shield has the concept of replacing Kevlar fabric with natural textiles called Cocos nucifera (CNS) sheath sheets. Multilayer shields are studied and developed using CNS and tested according to certain standards.


‘‘ The innovation of this creation was to replace Kevlar fabric in a multilayer shield with agro waste. Cocos nucifera natural sheath sheets have been selected as a potential alternative to Kevlar fabrics using AHP (Analytical Hierarchical Process) ’’, he said.


"From this analysis, it is found that the techno body of the economy can save up to 44% of the total fabrication cost compared to the Kevlar-based multilayer shield," he added.


In addition, the multilayer body shield based on Cocos nucifera sheets is beneficial in reducing environmental issues and increasing biodegradation. The cost of these powerful and economical shields is lower than that of synthetic fiber-based multilayer shielding systems.


Thus, the economic techno body shield can be used efficiently as an alternative shield to the Kevlar body shield and it is also ready to be commercialized to society as one of the proactive measures to help use innovations from green and environmentally friendly materials.
