Development of High Performance FRP Crush Box

This article surveys existing cohesive zone models (CZM) and their use in numerical simulations for analysis impacts on composite structures and predicting the damage induced. These models are used for matrix cracks and delamination. The first part of article gives the required background on failure criteria for predicting the onset of delaminations, on fracture mechanics and the various types of CZM. The second part discusses applications of CZM to several types of impact problems with composite structures. Applications for these models to other problems are briefly mentioned at the end. CZM are now part of state of the art numerical simulations with progressive damage analysis.

“…Fiber-reinforced plastics (henceforth FRP) have been researched intensively for the purpose of vehicle weight reduction due to their outstanding specific modulus and strength levels [2][3][4][5][6][7][8][9][10][11]. For example, carbon-fiber-reinforced plastics (CRFPs) reduce the weight when replacing metallic parts by more than 50%.…”

The functions of circular braided composite materials in suspension stabilizer bars were investigated in an effort to reduce vehicle weights. By applying these composites in the automotive industry, productivity was also considered and was increased by using a third-generation method of carbonfiber-reinforced plastic fabrication (the PulPress ® process). Analytic and finite element analyses were carried out to determine the geometric parameters of the composite stabilizer bars. The static and dynamic properties were measured and compared with theoretical estimations. The feasibility of the third-generation method is discussed with a process capability analysis.
