Özet
In this paper we compare two manufacturing techniques namely vacuum infusion and compression molding, used in manufacturing S2 glass fabric/epoxy composites for high-speed impact applications. Even though compression molding and vacuum infusion are two widely used manufacturing techniques, the resulting product may be very, different. Compression molding has the advantage of achieving a much higher fiber density for the same thickness. With a higher fiber density, the composites made by compression molding have better mechanical properties than a composite made by vacuum infusion. However, vacuum infusion is faster and more. economical. The mechanical performance of the composites manufactured by these two processes are compared by performing tensile tests and high speed impact tests for the' determination of the limit speed V-50. For the same number of plies, preliminary results for compression molded specimens indiCate a 50% increase in stiffness and a 40% increase in strength. Also, for panels of the same thickness, the V-50 was higher for compression molding specimens.
