摘要

In this work, the mechanical properties of many types of structural composite materials (Samples 1–20) are studied, revealing useful links between the structure, behavior during deformation, and their overall performance. It can be observed that Sample 1 is stiff, but it breaks suddenly and doesn’t absorb much energy. In contrast, Samples 2 through 10 remain flexible, experience a lot of plastic deformation, and are tough. Analyses of Samples 11–20 point out three categories: first, samples 11–13 experience brittle and quick failure; the next category, samples 14–17, last longer and eventually break through delamination; lastly, samples 18–20 display the highest toughness due to preferred fiber-matrix attachment and strong resistance to damage. It is revealed that sample 19 shows the best results as it has the highest yield strength of all samples, the top load it can handle, and strong resistance to creep and fluctuations in stress, with a ductile failure. The reason is connected to powerful molecular bonds, similar material structure, and strong dislocation pinning. Sample 20 can be a good option since it maintains 94% of its strength under stress and bears 93% of its normal load. Based on the findings, it is clear how various fiber-matrix bonds (such as how well the fiber fits the matrix) and the quantity of voids relate to plastics behaving elastically, viscoelastically, or plastically, and eventually failing in specific ways. For applications that must handle large loads and need extra safety, Sample 19 is recommended.
