Effect of the addition of modified mica on mechanical and durability properties of FRP composite materials for civil engineering
Bibliographic record
Abstract
Abstract The durability of fiber reinforced polymer (FRP) composite materials in humid and harsh environments is an important consideration for acceptance of these materials in civil engineering applications. Reducing the moisture ingress may improve the durability of FRPs. The addition of modified inorganic powder, such as clay nanoparticles, may improve several important properties of polymers, such as barrier properties, fire retardancy, dimensional stability, and mechanical strength. The present work aims to evaluate the effect of the addition of modified mica on FRP properties used in civil engineering applications. To conduct this preliminary study, the following steps were taken: (1) prepare and characterize composites made from lab‐made modified mica, (2) determine the maximum water uptake, water absorption rate and coefficient of diffusion, (3) characterize the mechanical properties, and finally, (4) evaluate the UV resistance. The experimental results show that the use of nanoparticles leads to a decrease of the coefficient of diffusion of water and a significant increase of stiffness and UV resistance. POLYM.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
