The Effective Flexural Modulus of Filament Wound GRP Tapered Poles

open access: yesTehnicki vjesnik - Technical Gazette, 2020
The composite lighting poles are filament wound GRP tapered tubes with a variable wall thickness across the length. In this study, the effective flexural properties of GRP poles have been determined, experimentally and theoretically. Cantilever bending tests were performed on full-scale GRP tubes and the effective flexural modulus was calculated from ...
