Abstract

fetched live from OpenAlex

The high molecular polyetheramines curing agent(such as D-2000 and T-5000)and flexi- ble epoxy resin(EP)(such as DER-732,EPICLON 830,133L)were introduced into EP systems,and the influence of modifier species and content were studied on tensile performance and bonding perfor- mance for EP systems.The research results showed that the introduced high molecular polyetheramines and flexible EP could remarkably enhance elongation at break of EP systems.The optimum system with high molecular polyetheramines was E-51/D-400/D-2000 system,the elongation at break and the tensile strength were 53.6%and 17.8 MPa respectively when mass fraction of D-2000 was 30 phr.The optimum system with flexible EP was E-51/DER-732/D-400 system,the tensile strength and the elon- gation at break were 13.0 MPa and above 130%respectively when mass fraction of DER-732 was 25 phr.The tensile shear strength of EP systems with high elongation at break was about 25 MPa for bonding aluminum.

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.
