This research successfully introduced an innovative lightweight tube made from lightweight PU Foam material
and reinforced with glass fiber. The key findings from the tests are as follows: Glass fiber-reinforced polymer
(GFRP) tubes without polyurethane (PU) foam withstood a pressure of 4.03 kN in compression testing. The
specimen with 5 % graphite filler had the highest density at 0.262 g/mm3
, while the specimen with 10 %
graphite filler had the lowest density. The specimen with 5 % graphite filler also exhibited the highest hardness
(19.5 Shore Hardness D), whereas the specimen with 20 % graphite filler had the lowest hardness (13.2 Shore
Hardness D). The contraction of PU foam significantly influenced the material strength. GFRP tubes reinforced
with PU foam offer advantages in terms of material lightness and improved material strength. These tubes can be
applied in structural, automotive, and aerospace applications
