The Effect of Inter Laminate Layer on Flexural Strength for Unsaturated Polyester Resin Reinforced Hybrid Fabric Composite

The present study aims to examine the effects quality, sequence and direction of the layers for three types of fibers: orthogonal glass fibers, randomized glass fibers, short carbon fiber cut on the bending test using a bonding material, unsaturated polyester. The manual modulation method was used to manufacture a composite material of unsaturated polystyrene and three layers of glass fibers with 25% volume fracture a compound material of unsaturated polystyrene supported by chopped carbon fiber and fractions of 10% volume, and the manufacture of the hybrids with (glass - regular glass - random glass) and layers (regular glass - random glass - regular glass) and layers (regular glass carbon 5% - regular glass). The results showed that the fiber orientation played an important role in determining the mechanical behavior of the composite materials. The values of the ionic coefficient increased by increasing the number of orthogonal layers of glass compared to random samples. The flexural stress for epoxy reinforcement by different kind hybrid composite according to the results, the mechanical behavior between the glass and hybrid composites may be due to the differences in the mode of load transfer at the fiber - matrix interface and, consequently, in the interfacial bond strength and who fiber can be interlaminating layers of composite.
