Effects of Different Reinforcements for Improving Mechanical Properties of Composite Materials

34816

The traditional materials are inadequate to the needs of modern manufacturing such as high mechanical and technological properties. There is a conflict with the demands of high-strength and lightweight, however the composite materials with diverse reinforcements provide each of the requests. Therefore, the use of the composite materials in industrial applications has become increasingly necessary. Sheet Molding Compounds (SMC) is a production method which the thermoset polymer composite parts with high-strengths can be manufacture in series for many areas, including automotive.In this study, the mechanical properties of two different SMC materials were examined which obtained using woven glass fibers and nonwoven (random) fibers as reinforcements to increase strengths of the resulting material. The experimental results showed that the tensile strength of the SMC specimen with random fibers reached an average value of 67.58 MPa, but the average value of the specimen with woven glass fiber reinforcement in the same conditions and a weight ratio was reached up to 137.29 MPa. With this new material, the tensile strength values were increased approximately to double.
