A three⁃dimensional numerical damage model study of composite material laminate with polyurethane coating under impact loading
To address the issue of damage caused by low-speed impacts on composite material laminates coated with polyurethane coating
a numerical analysis method based on three-dimensional progressive cumulative damage in composite laminates and a yield damage criterion for polyurethane coatings was proposed. Firstly
a damage numerical model of polyurethane coating-carbon fiber reinforced composite laminates under erosion was established
and a Vumat subroutine was written. Subsequently
referring to the ASTM D7136 test standard
impact tests with various energy levels were conducted on samples coated with 1 mm and 2 mm polyurethane coatings and uncoated samples. Simultaneously
the proposed damage model was employed to study the formation reasons and propagation patterns of primary damages such as fiber damage
matrix damage
and delamination
thereby revealing the mechanism of polyurethane coating in absorbing impact energy. The results indicated that the mechanical response results calculated by the proposed damage model showed a high degree of agreement with the test results
validating the correctness of the proposed model. Additionally
comparative tests demonstrated the enhancement effect of polyurethane coating on the impact damage resistance of carbon fiber composite laminates. The findings of this study can provide a reference for the design of protective coatings for aircraft.
