Influence of Loading Speed on Tensile Strengths of Glass Fiber Reinforced Polymer Composite Experimental and Numerical Studies

Abstract:

The thermomechanical behavior of glass fiberreinforced polymer (GFRP) composite was studied. The thermal characteristics and the mechanical properties are determined over a temperature range from ambient to 60°C. The calcium carbonate filler of the amount 15% of the weight of the resin have been used in order to improve the mechanical proprieties and attempt to observe the possibility of replacement a part of expensive resin by cheap filler. The loading speed refers to the crosshead velocity, which has direct Proportionality with strain rate. After the specimens are exposed to temperatures ranging from 20 , 40 to 60 , the results show a greater elongation indicate a greater ductility that explain we improved the tenacity of specimens, Especially for temperature 60, this propriety is more suitable for vehicle industry. Results in terms of simulation using a code program (Abaqus) are presented, The Johnson–Cook (JC) model was chosen as the constitutive model and then the finite element solutions were compared to the experimental results. A good agreement of the numerical curves with the target loading curves was found.
