Physical and Mechanical Properties and Durability Characteristics of New Pultruded GFRP Bars with Thermoplastic Resin
Bibliographic record
Abstract
This paper presents an experimental study that investigated the physical and mechanical properties as well as the tensile properties, transverse shear strength, and interlaminar shear strength of a newly developed glass fiber–reinforced polymer (GFRP) bar pultruded with a novel thermoplastic resin. The performance of the newly developed thermoplastic GFRP bar was compared with that of conventional thermoset-based GFRP bars pultruded with vinyl-ester resin to evaluate its suitability as internal reinforcement for concrete structures. Moreover, this study evaluated the durability characteristics of the newly developed thermoplastic GFRP bars under alkaline environmental conditions. The experimental results presented herein show that the performance of the newly developed thermoplastic GFRP bars tested exceeded that of the minimum mechanical properties specified in recent standards. Moreover, the new GFRP bars displayed high long-term durability performance. The findings of this study indicate the potential of the newly developed thermoplastic GFRP bars as a viable alternative to conventional reinforcement materials. Their favorable mechanical behavior supports their use in concrete structures, contributing to improved durability, sustainability, and overall performance.

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.
