KUALITAS PAPAN KOMPOSIT BERLAPIS FINIR DARI SABUT KELAPA DAN PLASTIK POLIETILENA DAUR ULANG: VARIASI UKURAN PARTIKEL SABUT KELAPA
Abstract: Agricultural fibers
are currently used as a substituted resource to wood-based products. One of
agricultural fibers that has been developed and become a resource for panel
products is coir (coconut fiber). The purpose of this study is to evaluate the
quality of veneered composite board made of coir and recycled polyethylene
(RPE). The target density of board samples was 0.7 g/cm3. The board
construction type is core type composite board (three layers). Veneers from
Meranti (Shorea sp.) were used as face and back layers and coir was in the core
layer. RPE composition was 50% based on coir particle and veneers oven dry
weights. Recycled plastics were placed in three layers, 30% on the face and
back layers, and 70% in the core layer. The coir sizes were under 1 cm, 1 cm, 5
cm, 10 cm, and 10 cm up (along coir size). The composite board samples were
tested by JIS A 5908 – 1994. Each parameter was measured in three replications.
The research results obtained are as follows : (1) Veneered composite boards
made of coir and RPE fulfill the JIS A 5908 standard in term of density,
thickness swelling after 2 and 24 hours of water immersions, modulus of
elasticity, modulus of rupture and internal bond, and (2) The coir size did not
significantly affect the properties of composite board.
