This paper presents the result of research on equipment development of vacuum injection molding technique for preparation the chopped bamboo fiber polymer composite and some properties of obtained composite material. For the vacuum injection molding technique, firstly the dry fibers were plated in the mold. Then the mold was closed by the vacuum bag, the air inside the mold was sucked out by a vacuum pump, due to the difference of the pressure in side and outside the mold, the polymer liquid was transferred to the closed mold and impregnated the bamboo fiber. The polymer used in this research was unsaturated polyester and epoxy resin. The obtained composite materials were evaluated by measuring some mechanical properties, such as tensile strength, compressive strength, and flexural strength according to ASTM standards.
