Abstract
Composite is a combination of two or more materials that have different mechanical properties
and characteristics. One of the reinforcement materials or reinforcement that is widely used is natural
materials. One of Indonesia's natural materials and a very large source of bamboo is widely used in
building construction as an alternative to wood because it has high flexibility and strength. To balance
the strength of bamboo with high tensile strength while low flexural strength, a solution is needed to
maximize the strength of bamboo by combining it with a bamboo composite system. In this study, bamboo
that has been processed into woven sheets manually with plain weave type is then given a certain amount
of epoxy resin and then a Tensile Strength Test is carried out using ASTM D3039 / D3039M and a
flexural test using ASTM D7264 / 7264M to obtain maximum composite and flexural strength. After the
test was carried out, it was continued by observing the microstructure of the specimen using SEM
(Scanning Electron Microscope). The results showed the tensile test value with a value of 50 Mpa
compared to the ABS tensile strength value of 53 Mpa, the Modulus of Elasticity with a value of 0.38 GPa
compared to the ABS modulus of elasticity of 0.41 Gpa. The results of the flexural test obtained flexural
strength with a value of 47.06 Mpa compared to the value of ABS flexural strength of 49.6 Mpa, flexural
modulus with a value of 0.52 Gpa compared to the value of ABS flexural modulus of 0.55 Gpa.
