This study aims to develop a fabrication process that improves the strength of glass fiber. The glass fiber strength was investigated by a fragmentation test. The fabrication process suggested in this paper made good use of the fracture mechanism of glass fiber. Before poring a resin to the mold, moisture around glass fiber was removed by a vacuuming treatment to improve the fiber strength. It was ascertained that the resin around the glass fiber acts as the moisture barrier. So, the strength reduction by moisture attack can be removed until the moisture in a matrix reaches to glass fiber surface. Fiber strength fabricated using the proposed process increased about 33% compared to the fiber strength fabricated by conventional process. On the other hand, interfacial strength decreased by vacuuming treatment, since the surface treatment might be removed during this process.
