The Bending Moment Resistance of Corner Joints Reinforced with Glass Fiber Polymer

Öz

Aim of study: This study aimed to determine the effects
of glass fiber reinforced polymer (GFRP) and adhesives type on the diagonal
compression and tensile strength in L-type corner joints connected by a wood
biscuit.

Material and Methods: Medium density fiberboard coated with melamine plate
(MDFlam), wood biscuit with a size number of 20 (dimension: 56 × 23 × 4 mm) as
the joining member, GFRP for strengthening purposes, and polyvinyl acetate
(PVAc-D4), polyurethane (PU-D4), and epoxy glues as adhesives were used. The
diagonal compression and tension tests were carried out under static load
according to ASTM-D1037 standards.

Main results: Results indicated that using GFRP
significantly increased the diagonal compression and tensile strength of L-type
corner joints connected by a wood biscuit.

Highlights: It is recommended to use the combination of GFRP and
epoxy adhesive in the corner joints to have better compression and tensile
strength in furniture.
