Abstract
In the present work a series of tests were performed on tubular CFRP specimens
with different winding angles. A plastic liner was used to study its effect on the
performance of the tubes. Lined and unlined specimens were loaded to different
load levels of about 40%, 60% and 80% of their burst strength. Each time, the
test was stopped when the required load value was reached. Suitable samples
were taken from the gauge length of the tubes close to the strain gauge positions.
The samples were cut in two directions, along and perpendicular to the fibre
direction and placed under microscope where they could be examined along and
traverse to the cut section. Micro-graphical study of the
