Abstract: This paper reported a case study on structure analysis and performance test for a water tank support based on polypropylene/glass fiber composites. A 3D model was first established with Catia software and then a simulation analysis was carried out with Ansys software to obtain the stress cloud. Rigidity and strength obtained from this model were in accordance with the requirements of theoretical analysis. On the other hand, a series of performance measurements were performed, which included impact, rotation torque, weathering, pull-out and aging tests. The results indicated that not only the performance of auto water tank supports met the requirements, but it also achieved a lightweight nature for a cost-effective demand.
