Abstract

Sandwich composite is a type of composite that has enough strength when it is used as a primary or secondary structure. Composites also have the advantage on their mechanical properties, corrosion resistance, small density and simple manufacturing process. This research aims to investigate the effects of adhesive variations on composite sandwich with arenga pinnata fiber as skin and paraserianthes falcataria sawdust as core on the bending strength of the material. The materials on this research are arenga pinnata fiber, unsaturated polyester resin 157 BQTN-EX, versamid 140, chloroprene, sawdust from paraserianthes falcataria sawdust and urea formaldehyde. This specimen was made by using press casting method with 2 mm of skin thickness and 10 mm of core thickness. The bending strength test refers to the ASTM C 393. The method used in the process of making this composite is hand lay-up method. The results showed that adhesive variation affected the bending strength of sandwich composites where the highest value was achieved using adhesive versamid 140, with bending strength value of 25.86 MPa. Observation on the fracture surface of the bending test specimens showed that the composite sandwich with adhesive versamid 140 had a better inter-surface bond than the BQTN-EX yukalac and chloroprene
