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.

针对安全帽用天然纤维基复合材料领域，选取23篇文献开展详细综述研究；将从文献中提取的必要参数录入Excel文件并开展分析，同时对每篇文献中的全部实验结果进行录入与横向对比。需注意，某篇文献报告的偏低结果，可能高于另一篇文献的报道值。本次录入的数据涵盖文献标题、发表年份、所用基体、增强相、填充剂、取向状态、增强相体积分数、拉伸强度、弯曲强度、冲击韧性以及含水率等。本次研究共采集得到108组有效数据点，所有冲击韧性结果均统一转换为焦耳单位；试样尺寸信息要么取自各文献原文记录，要么依据文献所报告的ASTM标准确定。
