Abstract

fetched live from OpenAlex

In this study, the objective was to develop hybrid composites combining the semi-crystalline engineered polysaccharide α-1,3-glucan (Nuvolve™) with typical long glass fiber in a polypropylene matrix to optimize specific indicators of performance while also considering environmental attributes. Morphological analyses were conducted in conjunction with the evaluation of mechanical performance of these hybrid composites to gain further understanding of filler-matrix interaction. Optimum loadings of the polysaccharide / glass fiber system were identified as promising alternative to the current glass fiber / polypropylene incumbent material utilized in many commercial application (e.g. by Ford Motor Company for body interior and under-the-hood applications). Formulations with 10/15 (e.g. 10 wt.% polysaccharide and 15 wt.% glass fiber) or 10/20 showed an overall increase of >100% with respect to modulus, strength and impact properties while also demonstrating a density reduction of up to 13%. Interestingly, the life cycle analysis showed that addition of only 10 wt.% polysaccharide was able to save 4,720 liters of fuel for every ton of polysaccharide used in vehicles. Therefore, hybrid reinforced thermoplastic composites offer a balance of engineering and environmental performance to exceed materials in use. These new composites are commercially viable while also advancing the environmental stewardship and eco-efficiency within the automotive industry.

Full frame distilled prediction

Teacher imitation

Not 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.
