Abstract

Recycled fibers are of interest to produce fiber reinforced cement composites while reducing some environmental impacts such as waste disposal and raw materials consumption. In this paper, four plastic and three steel fibers obtained from waste were studied. The aim of this article was to characterize their pull-out response. Recycled steel fibers were recovered from tires, while one plastic fiber was produced from straps and three fibers were fabricated from PET bottles with different shapes to compare the effects of geometry. Recycled steel fibers showed higher adhesion and strain energy density than plastic ones. The adhesion and elastic modulus of these recycled steel fibers are of interest for fiber reinforced mortar and concrete applications, while plastic fibers could contribute to improve cohesion and to mitigate shrinkage cracking at early ages.

从废料中回收的塑料和钢纤维的拉拔性能

回收纤维在生产纤维增强水泥复合材料方面具有重要意义，同时还能减少废物处理和原材料消耗等对环境的影响。本文研究了从废弃物中提取的四种塑料纤维和三种钢纤维。本文的目的是描述它们的拉出响应特性。回收的钢纤维是从轮胎中回收的，而一种塑料纤维是用带子制成的，三种纤维是用不同形状的 PET 瓶制成的，以比较几何形状的影响。与塑料纤维相比，回收钢纤维显示出更高的粘附力和应变能密度。这些回收钢纤维的附着力和弹性模量对纤维增强砂浆和混凝土的应用很有意义，而塑料纤维则有助于提高内聚力和减少早期收缩开裂。

期刊介绍： The Journal of Reinforced Plastics and Composites is a fully peer-reviewed international journal that publishes original research and review articles on a broad range of today''s reinforced plastics and composites including areas in: Constituent materials: matrix materials, reinforcements and coatings. Properties and performance: The results of testing, predictive models, and in-service evaluation of a wide range of materials are published, providing the reader with extensive properties data for reference. Analysis and design: Frequency reports on these subjects inform the reader of analytical techniques, design processes and the many design options available in materials composition. Processing and fabrication: There is increased interest among materials engineers in cost-effective processing. Applications: Reports on new materials R&D are often related to the service requirements of specific application areas, such as automotive, marine, construction and aviation. Reports on special topics are regularly included such as recycling, environmental effects, novel materials, computer-aided design, predictive modelling, and "smart" composite materials. "The articles in the Journal of Reinforced Plastics and Products are must reading for engineers in industry and for researchers working on leading edge problems" Professor Emeritus Stephen W Tsai National Sun Yat-sen University, Taiwan This journal is a member of the Committee on Publication Ethics (COPE).
