Eco-hybrid composite failure behavior of two serial bolted joint holes. Journal of Engineering and Technology, 7 (1). pp. 114-124. ISSN 2180-3811 (2016)
Abstract
This study investigates the geometrical effect of two serial bolted joint holes on hybrid composites. Geometry parameters studied were edge distance-to-upper hole centre (E/D) and the distance between centers of two holes diameter (K/D). The hybrid composites were fabricated using kenaf woven fiber and E-glass woven fiber. Composite specimens were manufactured through hot press molding compression method at 180oC. The bearing test was conducted according to ASTM D-5961 ‘Procedure C’. The results show bearing strength and failure mechanisms of hybrid composites highly depend on the geometry parameters. Hybrid composites with the highest geometrical parameter, K/D= 5 and E/D= 4,show the highest bearing strength (32.381 MPa) while hybrid composites with the lowest geometrical parameter, K/D= 2 and E/D= 2,exhibitthe lowest bearing strength (20.445 MPa). Therefore, this indicates that bearing strength increases with increase of K/Dand E/Dratio. The failure behaviors observed were shear-out modes, bearing modes and net-tension modes.
