Natural fiber based

23 articles are selected for the detail review in natural fiber based materials for safety helmet and required parameter from the articles are registered in an excel file and analysed. All the experimental results from each of the articles were registered and compared against each other. Assumed lower results reported by one articles may be higher than teh value reported by the other. title of the article, year of publication, matrix used, reinforcement, filler used, orientaion, volumetric ratio of the reinforcement, tensile strength, flexural strength, impact resistance and moisture constent are some of the data registered. 108 data points are collected. the impact resistance is converted to joules sample dimensions registed on each of the articles or as per the ASTM standard the papers reported.
