Structural Behavior and Design of Recycled LDPE-FRP Hybrid Beams for Bridge Collision Protection

Abstract

Abstract The paper summarizes results of a pilot study that evaluates both the service and ultimate short-term behavior of hybrid beams made of recycled low-density polyethylene (LDPE) plastic matrix and reinforced with fiber-reinforced polymer (FRP) ... Practical Applications The hybrid low-density polyethylene (LDPE)–fiber-reinforced polymer (FRP) beam system provides a versatile, sustainable solution for impact protection across multiple infrastructure applications. In industrial facilities, it ...
