Open-Hole Tensile Experiments of Thermoplastic Composite Laminates and Finite Element Analysis

Öz

Composites materials are used in automotive industry for their light weight and high strength properties. With the progress signed in a new polymer matrix, recyclable thermoplastic composite (TPC) materials, became an excellent alternative to conventional materials. In this paper glass fiber reinforced TPC materials manufactured with lamina sequence techniques of polyamide, polypropylene matrix materials were used to realize open hole tensile tests. Finite Element Analysis (FEA) were also performed by using commercial software. The open-hole tensile tests results were compared with standard tensile tests results to clarify circular hole influence on the stress-strain behavior of the TPC materials. FEA results were also compared with the experimental data.
