Abstract | This study focused on the flexural behaviour of a new type of composite beam, consisting of pultruded glass fibre reinforced polymer (GFRP) profiles filled with waste-based composite panels. Recycled plastic and wood composite panels are placed inside the GFRP rectangular hollow section with vertical and horizontal orientations, then gaps inside the panels are filled with cementitious grout. A total of four composite beam samples (e.g., three filled and one hollow) are tested under three-point bending at a shear span-to-depth ratio of 6. According to the test results, filling hollow tubes with waste-based layered composite panels increases the load carrying capacity by 2.3 times, while stiffness increases by 36%. Panels oriented horizontally inside hollow tubes show slightly greater load carrying capacity than panels oriented vertically, but panel orientation does not affect stiffness properties. When wood composite panels are used instead of recycled plastic panels, the beam stiffness increases by 7% but it does not affect the load carrying capacity. This study indicates that the filler materials do not need to be very high quality as the overall behaviour of the beam is governed by the confinement effect of the exterior GFRP panel. Moreover, the proposed concept of the beam can lead to the development of a highly sustainable railway sleeper. In addition, this development is consistent with the Australian government's goal of achieving net zero carbon emissions by 2050 through the encouragement of circular economies. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024. |
