Recycling scheme of plant fiber reinforced composites in temporary buildings
植物纤维增强复合材料在临时建筑中的循环利用方案

摘要

植物纤维增强复合材料因其轻质、高强度、可再生等特性，在临时建筑领域具有显著的应用潜力。针对临时建筑频繁拆建、材料浪费与环境压力等问题，本文提出了一套基于生命周期管理的循环利用方案，从材料回收、性能再生、结构再设计与产业链衔接等方面进行系统探讨。通过建立分级回收体系、优化纤维处理工艺以及引入可拆卸式结构设计，可显著提升材料的重复使用率与结构安全性。结合实际工程案例，验证了该方案在降低碳排放、减少建筑废弃物及提升经济效益方面的可行性与优势，为临时建筑的绿色可持续发展提供了可操作的技术路径与管理模式。

Abstract

Plant fiber reinforced composites (PFRC) have significant application potential in the field of temporary buildings due to their characteristics of light weight, high strength, and renewability. Aiming at the problems of frequent demolition and reconstruction of temporary buildings, material waste, and environmental pressure, this paper proposes a recycling scheme based on life cycle management, which systematically discusses aspects such as material recycling, performance regeneration, structural redesign, and industrial chain connection. By establishing a hierarchical recycling system, optimizing fiber processing technology, and introducing detachable structural design, the reuse rate of materials and structural safety can be significantly improved. Combined with practical engineering cases, the feasibility and advantages of this scheme in reducing carbon emissions, minimizing construction waste, and enhancing economic benefits are verified, providing an operable technical path and management model for the green and sustainable development of temporary buildings.
