摘要：This research examines the consequences of low-velocity impact loadings and
distilled water ageing on E-glass and S-glass fiber-epoxy reinforced composite
pipes that were exposed to internal burst pressure and followed by axial
compression. The composite pipes, which comprised of four defiant symmetric
layers with (±55°)3 winding angles, were produced by the filament winding
procedure. The samples were reduced from the pipes to the required experimental
length. The samples were then immersed in 90 °C water for the time period
intermissions of 600, 1200, and 1800h. The impact heaps of three various
dissimilar energy intensities (7.5 J, 10J, and 12.5 J) were employed and pursued
by monotonic internal burst pressure and axial compression tests. SEM pictures
were taken and the relationship between the ageing period and the point of impact
of the composite pipes was identified. The results show that the internal burst
pressure failures are contingent to the applied impact energies. Finally, it can be
concluded that the burst pressure and the compression behaviours of the
conditioned specimens are significantly reduced due to environmental ageing.
