Abstract

Short-term aging properties of a tri-axial polymer composite material for mobile bridges operating in high heat environment were analyzed with progressive failure simulation software and physically tested for verification. The work focused on thermal cycling, impact damage and ultra violet (UV) exposure effects on degradation of the composite material tensile and compressive strengths as well as fatigue life. Tests and simulations showed that short-term thermal cycling and UV exposure did not have significant effects on the composite mechanical properties. Simulation results agreed well with the test data.
