AXIAL PERFORMANCE OF NATURAL FLAX-SKINNED FRP SANDWICH PANELS WITH VARYING SLENDERNESS RATIOS

摘要：

　　This study examines the axial performance of sandwich panels with flax fibre reinforced polymer skins(FFRP)and compares them with conventional glass fibre reinforced polymer skins(GFRP).Thirty-six specimens with a polyisocyanurate foam core cross-section of 50x100 mm2 ranging from 500 to 1500 mm height were fabricated.The specimens exhibited a slenderness ratio ranging from 22 to 62 and were tested under concentric axial compression with pin-ended connections.Panels with three FFRP layers showed equivalent axial strength to those with a single GFRP layer of 85%the total FFRP skin thickness.This was consistent across all slenderness ratios studied.Panels experienced failure due to global buckling at slenderness ratios higher than 50,whereas failure due to localized failures were observed at slenderness ratios below 32.Mixed failure modes were observed in the intermediate range.
