  Abstract

The elevated temperatures affect the service performance of the fibre-reinforced polymers. To improve performance at elevated temperatures, four types of interlayer hybrid woven fibre-reinforced polymer thin-walled tubes (HFRPTTs) were designed and prepared (all-carbon fibre HC4FRPTT, glass-carbon fibre HG1C3FRPTT, Kevlar–carbon fibre HK1C3FRPTT, and basalt-carbon fibre HB1C3FRPTT). The change rate of mass loss was obtained at different elevated temperatures (100 ℃, 200 ℃, 300 ℃, 400 ℃). Quasi-static axial compression tests and industrial microscopy were employed to analyse the variations in mechanical properties, energy absorption characteristics, and microstructural changes. Digital scanning calorimetry (DSC) and thermal gravimetry analysis (TGA) studied the thermomechanical characteristics before and after exposure to elevated temperatures. The results show that the mass loss rate of Kevlar fibre is the highest, leading to the maximum mass loss rate for HK1C3FRPTT. The mechanical properties of HFRPTTs (compressive strength, specific strength, and peak load) are influenced by the competing effects of resin matrix post-curing and thermal degradation. The critical temperature for HFRPTTs lies between 300 and 400 ℃. Below 300 ℃, the failure mode of HFRPTTs is a stable annular folding. The energy absorption characteristics of HFRPTTs are influenced by the combined effects of resin post-curing, thermal degradation, and mass loss. The variation patterns of HFRPTT's performance at different temperatures provide a reference for its service.
