Abstract Scope |
The single fiber pull-out test (SFPT) is used to characterize the interaction between fiber and resin in a fiber-reinforced composite. This is accomplished by embedding a fiber into its matrix material and measuring the force response as the fiber is pulled out. The SFPT is useful because it is inexpensive and the fabrication of specimens is straightforward. The test also gives the apparent interfacial shear strength, which indicates the fiber’s ability to transfer load into the matrix. The load transfer capacity in a fiber-reinforced composite material significantly affects its mechanical performance. A better understanding of this problem will lead to more informed composite designs. A computational model of this test would allow for the optimization of geometric ratios, insight into stress and traction distributions, visualization of failure mode and progression, and inexpensive validation for future modeling. In this study, a quasi-static finite volume model of the SFPT was created and compared with experimental data. The model is able to capture the progression of failure, the force response, and make predictions on the different failure modes seen in the SFPT. |
