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

Abstract

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.
