Kekuatan Sambungan Dua Tampang Pada MDF Dengan Alat Sambung Pasak WPC

Abstract

MDF (Medium Density Fiberboard) and WPC (Wood Plastic Composite) are innovative results of using sawdust waste to overcome the problem of wood scarcity. This study used a WPC Teak dowel because it has high shear strength and does not cause rust marks. This study was conducted to determine the value of the MDF connection capacity using WPC Teak dowel connectors and to determine the connection failure mode based on the EYM (European Yield Model) theory. This study used a WPC Teak dowel with a diameter of 6 mm, 8 mm, 10 mm, and 12 mm. The type of connection is a double-shear wooden joint using MDF. The test was carried out at the Structural Laboratory, Civil Engineering Department, Tidar University using a Compression Testing Machine to get the value of the connection capacity and test failure mode based on the MDF bearing strength and WPC Teak post failure referring to ASTM D764-97a. The test results obtained an average connection capacity value WPC dowel with a diameter of 6 mm, 8 mm, 10 mm, and 12 mm, respectively, which was 1094 N; 1870 N; 2439 N; and 3462. The highest average connection capacity value at 12 mm diameter was 3462 N, and the lowest at 6 mm was 1094 N.

Tinjauan Sifat Fisis dan Mekanik Antara Board HDF Reguler Dengan Tipe Produk CDF Produksi PT Sumatera Prima Fibreboard Indralaya

“…Kualitas MLDF, MDF, dan HDF dapat ditinjau dari sifat fisis dan juga sifat mekanisnya. Untuk papan serat, sifat-sifat fisik yang umumnya diukur meliputi kerapatan (densitas), kadar air, Modulus of Rupture (MOR), Modulus of Elasticity (MOE), dan daya kerekatan (internal bonding), toleransi ketebalan, serta pengembangan tebal atau thickness swelling [4] [5]. Salah satu sifat fisik yang dimiliki MDF yaitu pengembangan tebal atau thickness swelling, untuk sifat pengembangan ketebalan papan serat akan berbanding lurus dengan kemampuan papan tersebut untuk menyerap air.…”
