Abstract

Abstract Natural plant fiber-reinforced polymer composites (PFRP) have emerged as an environmental-friendly material in the construction industry, but their creep behavior is a critical concern for load-bearing structures. This study investigates the creep behavior of flax fiber-reinforced polymer composites (FFRP) using the time–temperature superposition principle (TTSP). Due to the application of TTSP on the tensile creep behavior of FFRP is not fully understood, three potential methods for calculating the critical parameters during TTSP are compared to obtain an efficient application method to build the creep master curve. A 2,000-h long-term creep test is conducted parallelly on the same sample to validate the accuracy of the creep analysis results. The study proposes an ideal method to determine the key parameters in TTSP, providing valuable insights for the practical application of PFRP in the construction industry. Meanwhile, the research results in this study would be helpful in better understanding the creep behavior of FFRP via short-term accelerated tests.

基于时间-温度叠加原理的亚麻纤维增强聚合物复合材料蠕变分析

摘要天然植物纤维增强聚合物复合材料（PFRP）已成为建筑行业中的一种环保材料，但其蠕变行为是承重结构的一个关键问题。本研究采用时间-温度叠加原理（TTSP）研究了亚麻纤维增强聚合物复合材料（FFRP）的蠕变行为。由于TTSP在FFRP拉伸蠕变行为中的应用尚不完全清楚，因此对TTSP过程中计算关键参数的三种潜在方法进行了比较，以获得建立蠕变主曲线的有效应用方法。在同一样品上平行进行了2000小时的长期蠕变试验，以验证蠕变分析结果的准确性。该研究提出了一种确定TTSP关键参数的理想方法，为PFRP在建筑行业的实际应用提供了有价值的见解。同时，本研究的研究结果将有助于通过短期加速试验更好地了解FFRP的蠕变行为。

期刊介绍： Science and Engineering of Composite Materials is a quarterly publication which provides a forum for discussion of all aspects related to the structure and performance under simulated and actual service conditions of composites. The publication covers a variety of subjects, such as macro and micro and nano structure of materials, their mechanics and nanomechanics, the interphase, physical and chemical aging, fatigue, environmental interactions, and process modeling. The interdisciplinary character of the subject as well as the possible development and use of composites for novel and specific applications receives special attention.
