Abstract

Bamboo is an eco-friendly material with light weight, high strength, short growth cycle and high sustainability, which is widely used in building structures. Engineered bamboo has further promoted the development of modern bamboo structures due to its unrestricted size and shape. However, as a ﬁ ber-reinforced material, fracture damage, especially Mode I fracture damage, becomes the most likely damage mode of its structure, so Mode I fracture characteristics are an important subject in the research of mechanical properties of bamboo. This paper summarizes the current status of experimental research on the Mode I fracture properties of bamboo based on the three-point bending (TPB) method, the single-edge notched beam (SENB) method, the compact tension (CT) method and the double cantilever beam (DCB) method, compares the fracture toughness of different species of bamboo, analyzes the toughening mechanisms and fracture damage modes, discusses the applicability of different theoretical calculation methods, and makes suggestions for future research priorities, aiming to provide a reference for future research and engineering applications in related ﬁ elds.

竹材I型断裂行为试验研究综述

竹子是一种重量轻、强度高、生长周期短、可持续性高的环保材料，被广泛应用于建筑结构中。工程竹子由于其不受限制的大小和形状，进一步促进了现代竹结构的发展。然而，竹材作为纤维增强材料，断裂损伤尤其是I型断裂损伤成为其结构最可能出现的损伤模式，因此I型断裂特征是竹材力学性能研究的重要课题。本文综述了基于三点弯曲法(TPB)、单边缺口梁法(SENB)、紧致拉伸法(CT)和双悬臂梁法(DCB)的竹材I型断裂性能实验研究现状，比较了不同品种竹材的断裂韧性，分析了增韧机理和断裂损伤模式，探讨了不同理论计算方法的适用性。并对今后的研究重点提出了建议，旨在为今后相关领域的研究和工程应用提供参考。

期刊介绍： This journal publishes high quality peer reviewed original research and review articles on macromolecules and additives obtained from renewable/biobased resources. Utilizing a multidisciplinary approach, JRM introduces cutting-edge research on biobased monomers, polymers, additives (both organic and inorganic), their blends and composites. JRM showcases both fundamental aspects and applications of renewable materials. The fundamental topics include the synthesis and polymerization of biobased monomers and macromonomers, the chemical modification of natural polymers, as well as the characterization, structure-property relationships, processing, recycling, bio and environmental degradation and life cycle analysis of the ensuing materials, in view of their potential applications. Within this sustainability approach, green chemistry processes and studies falling within biorefinery contexts are strongly favored.
