Special Issue Information

Dear Colleagues,

Fiber-reinforced polymers are multipurpose materials widely used in advanced applications due to their excellent properties, e.g., their low production time, ability to produce long-term cost saving, light weight, and high durability properties. This Special Issue of Polymers is dedicated to fiber-reinforced polymers (FRPs). We are expecting to receive papers dealing with cutting-edge issues on the research and application of FRP composites in different areas.

The topics of this Special Issue include but are not limited to the durability and mechanical properties of FRPs, FRPs that are manufactured using different types of fibers (including recycled and natural fibers), FRPs containing nanomaterials, composite members manufactured with FRPs, retrofitting with FRP composites, the long-term properties of FRPs, fire protection for FRPs, and applications of FRPs. Both original contributions and reviews are welcome.

In this paper compressive strength and ultimate strain results in the current database of fiber-reinforced polymer (FRP)-confined concrete are used to determine the reliability of their design space. The Lognormal, Normal, Frechet, Gumbel, and Weibull distributions are selected to evaluate the probabilistic characteristics of six FRP material categories. Following this, safety levels of the database are determined based on a probabilistic model. An iterative reliability method is developed with conjugate search direction for evaluating the reliability. The results show that Lognormal and Gumbel distributions provide best probability distribution for model errors of strength and strain enhancement ratios. The developed conjugate reliability method provides improved robustness over the existing reliability methods owing to its faster convergence to stable results. The results reveal that the part of the database containing normal strength concrete (NSC) heavily confined (i.e., actual confinement ratio (flu,a/f’co) > 0.5) by low and normal modulus carbon fibers (i.e., fiber elastic modulus (Ef) ≤ 260 GPa) and moderately confined (i.e., 0.3 ≤ flu,a/f’co ≤ 0.5) by aramid fibers exhibits a very high safety level. The segments of the database with a low and moderate safety level have been identified as i) NSC moderately and heavily confined by higher modulus glass fibers (i.e., Ef > 60 GPa), ii) high strength concrete (HSC) moderately and heavily confined (i.e., flu,a/f’co > 0.3) by glass fibers, iii) HSC lightly confined (i.e., flu,a/f’co ≤ 0.2) by carbon fibers, and iv) HSC lightly confined by aramid fibers. Additional experimental studies are required on these segments of the database before they can be used reliably for design and modeling purposes. Full article
