Mechanical characterization of particulated FRP composite pipes: A comprehensive experimental study

Particulated fiber reinforced polymer (FRP) composite pipes encompass unidirectional continuous glass fibers (hoop glass), resin (thermoset vinylester) matrix, chop (discontinuous short fibers), and particulate reinforcement (sand) impregnated into resin. They are categorized based on their nominal diameter, pressure class, stiffness class. Mechanical characteristics of this class materials have not, to date, been comprehensively studied. As such, paper presents a systematic approach toward comprehensive experimental investigation mechanical characterizations in terms the axial hoop tensile strengths. The particulated FRP used current study along direction at approximately 89° angle. To assure data accuracy reliability, three batches associated with each pipe category were selected which slightly differ composition constituents. Three specimens per batch two types tests conducted specimen. 18 (2 × 3 specimens)) (9 for 9 axial). Therefore, 648 total 36 categories. Instron 5569A 8801 universal testing machines utilized split disc hydraulic machine tests. mean stresses standard deviations calculated Population Standard Deviation (PSD) equation then plotted against material results demonstrated that an increase decrease However, increasing ratio resin, glass, contributes enhancement This provides design guidelines engineers manufacturing industries.
