Abstract
Abstract Injection molded poly(trimethylene terephthalate) (PTT)/carbon fiber (CF) composites have been fabricated using a twin screw micro compounder. The effect of CF reinforcement on the thermal, mechanical, dynamic mechanical, and microscopic properties of the composite was investigated. Addition of 30 wt% of CF into PTT resulted in the significant enhancement of tensile (120%) and flexural (30%) strength compared to neat PTT. The rule of mixture was successfully employed for theoretical calculations of tensile modulus and the calculated values were compared with the experimental results. Similarly, CF reinforced (30 wt%) PTT composites exhibited an increase of more than a 150°C in the heat deflection temperature. Scanning electron microscopy analysis of the tensile fracture specimens revealed uniform distribution of the CFs with good polymer matrix and fiber adhesion. Overall, the results obtained indicate the enhancement of properties with increasing fiber content, confirming better fiber and polymer matrix compatibility. POLYM.

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 it
