Abstract

fetched live from OpenAlex

Abstract Biocomposites from renewable resources have been attracting increasing attention over the last two decades, mainly for two major reasons: first, environmental concerns, and second, the realization that our petroleum resources are finite. Nowadays, biofiber‐reinforced composites are seen as potential materials for many engineering applications. Unfortunately, there are still issues that limit their future applications including long‐term performance and processing variability. This article gives an overview of the wide variety of biocomposite processing techniques as well as the factors (moisture content, fiber type, content as well as coupling agents, and their influence on composites properties) that affect the processes. Before processing biocomposites, semifinished product manufacturing is also a vital part, which is illustrated. Processing technologies for biofiber‐reinforced composites are discussed on the basis of the thermoplastic matrix (compression molding, extrusion, injection molding, LFT‐D method, and thermoforming) and thermosets (resin transfer molding, sheet molding compound) as well as other implemented processes, that is, thermoset compression molding and pultrusion. Furthermore, we include comparative studies between different processes regarding the biocomposites' structure–property relationships.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
