| dc.description.abstract | Composite sandwich reinforcement kenaf fiber polyester with Styrofoam core is an alternative material
that has the potential to be developed as an application in various fields with an excess of nature that is
strong, lightweight, rigid, able to withstand bending loads, impact, vibration damping and sound. This
study is intended to overcome the problems of fishermen Muncar - Banyuwangi in the selection of
materials manufacture of safe fish robust and insulated to preserve or maintain the freshness of the fish
catch of fishermen low temperature. This study was conducted to determine the effect of variations in fiber
volume fraction of the increase in impact strength and bending composite materials sandwich.Untuk get
impact strength values using the tool impact test with a maximum capacity of 300 joules specifications,
pendulum mass of 20.9 kg, 0.83 m long pendulum arm, while to obtain bending strength values using a
universal testing machine capacity of 300 KN. Variations were used in this study is the percentage of fiber
volume fraction of 10% fiber, 20%, 30%, and 40%. The results showed that the variation of fiber volume
fraction of 40% had values higher impact strength and bending of 0.30 Joules / mm² and 5,65MPa than the
fiber volume fraction of 10% has impact and bending strength values were lower at 0.14 joules / mm2 and
0.30 MPa. So in this study limits the variation of fiber volume fraction of 10% to 40% proved that if the
greater the percentage of fiber volume fraction value will increase the value of impact strength and
bending in composite sandwich. | en_US |
