From the study and analyze the results of experiments of composite materials during fiber giant Mimosa pudica and coffee at the ratio 1: 2 0.75 cm long fibre-based mixed with Epoxy resin matrix, which functioned as the mechanical property testing, including absorbing energy from the bump or impact resistance and strength (Impact test), a tensile resistance and lengthen per cent (Tensile Test), and resistant to pressure (Compression Test) and tests for bending arc (3 Point Bending Test) found that when the best possible reinforcement fibers giant Mimosa pudica and coffee. To make the mechanical properties, the ability to absorb energy from the bump or impact resistance and strength increased up to 6.67 per cent including only lengthen the maximum increase of approximately 2.6 times compared to the work piece does not include glass reinforced section.That proportion by weight of the reinforcement that makes up the best mechanical properties are at 15% wt, but mechanical properties, however, the other side has less value when compared with non-reinforced sections. And, as with certain restrictions of the equipment and how it is tested, thus making this research should be resolved and further development.
