Abstract :

Fiber-reinforced polymer composites have played a dominant role for a long time in a variety of applications for their high specific strength and modulus. Especially, composites are classified via production types such as pultrision, wet lay up, spray up and molding. In this study, E-glass/resin composite laminates using powder-bond chopped-strand mat and fibers were fabricated using sheet molding compound technique. In preparation of the sheet molding compounds, unsaturated polyester, vinyl ester and epoxy were chosen as resin types. Unsaturated polyester and vinyl ester resins, which are very widely used in industry, were investigated in this study. The composites were characterized as high mechanical strength compound (HMC). An experimental investigation was carried out to determine the mechanical, physical and ballistic performance of HMC. The measured mechanical properties of HMC produced with 2400 text hundred wick on 450 g/m2 powder-bonded chopped-strand mat glass fiber and resin systems were compared for the three various resin types. Especially, the flexural strength, tensile strength and modulus were compared through compressed plate in hot mold. The ballistic test result showed that the HMC shields have ballistic resistance against 9 mm fragment simulating projectiles (FSP) up to 435 m/s projectile velocities. The extensions of damages in the composites were evaluated after impact. It was concluded that the HMC shields that made with unsaturated polyester and vinyl ester have capacity against the ballistic threats and potential to be used as shield materials level IIIA.
