Compression strength of composite glulam timber reinforced between first and second, third and fourth lamina

The use of GFRP sheet as reinforcement in Mengkulang glulam timber is considered to be
particularly promising, since the durability of Mengkulang glulam is improved and the
application is easier and faster due to lightweight properties of GFRP. Fiber reinforced
polymers incorporated with glulam provide significant gains in strength and stiffness, as well
as modify the rupture mode of these structural elements. In this study, compression test was
carried out on two types of specimen, reinforced and unreinforced Mengkulang glulam
block. Size of Mengkulang glulam block is 120 mm x 120 mm x 120 mm. For reinforced
glulam block, GFRP sheet was placed between the first and second layer, third and fourth
layer of lamina. The compression load was applied perpendicularly to the timber grain.
Compression test is carried out using Universal Testing Machine (UTM 1000kN).
Consequently it has been noted that by layering GFRP sheet between lamina could
increase the compression strength of glulam to resist load. Significant differences between
unreinforced and reinforced specimens are 12.6 percent. The highest average
compressive strength of reinforced and unreinforced glulam is 11154.05 kN/m2 and 9808.75
kN/m2 respectively.
