Pengujian Kuat Lentur Papan Kayu Akasia Menggunakan Lapisan/Coating Resin Epoxy
ABSTRACT
Strong testing flexures are testing based on wood mechanical properties, namely
holding the pull. The testing is done by three different variations on every strong
testing of flexible, strong flexible acacia, strong flexible wood coating with resin 1
layer, strong flexible wood coating with resin + fiberglass fabric 1 layer and strong
flexible wood coating with resin + fiberglass fabric 2 Look. At each test, the wood
class is grade is a grade I wood, and the percentage of the average increase of a
powerful coating resin coating 1 layer is 37.04 MPa or around 0.63% of the strong
value of acacia wood flexures, while the percentage of the average increase Strong
bending wood coating resin + 1 layer cloth is 22.13 MPa or around 0.23% of the
strong value of 1 layer coating coating resin. While the percentage of the average
rise of strong bending coating resin + 2 layer cloth is 4.38 MPa or about 0.03% of
the strong value of the coating resin + 1 layer cloth. This is caused by fiberglass
fabrics that add stronger strength to acacia wood. Through the standard coating
powerful testing procedure and using the average flexible calculation formula
obtained information that the increase in the dimensions of the test object produces
a strong bending strong increase, for beam test objects with a size of 50 cm x 5 cm
x 2 cm and get strong class I results with an average of 1238,226 kg/cm2
