Özet

Composite materials have been widely used in a wide range of engineering applications as automotive, aerospace, civil engineering structures, due to their higher strength/weight ratios. In this study, two types of thermoplastic  composites were produced by placing single and double layers of woven E-glass fabric between polyethylene films. The composites were prepared using the compression molder by curing the materials at a temperature of 190 oC under a constant pressure of 8,163 bar for 30 min. The mechanical properties were evaluated by means of tensile test and drop weight impact test. The drop weight impact tests were performed at the different energy levels beginning from 25 joule. Impact test results showed that with increasing energy level, contact force increased, while the contact time decreased. The maximum tensile load for the composite consisting single layer of woven E-glass fabric between polyethylene films was found 2073 N and for the composite consisting double layer of woven E-glass fabric between polyethylene films was found 3850 N. The average tensile strength was found 46 MPa for the composite consisting single layer of woven E-glass fabric between polyethylene films and 70 MPa for the composite consisting double layer of woven E-glass fabric between polyethylene films. It has been found that woven glass fabric reinforcement significantly increases the tensile strength of the polyethylene film.
