Design and Optimization of Floor Layers in Carbon Fiber Composites for Body‐in‐White Materials

Engineering Reports, Volume 8, Issue 6, June 2026.
The PSO‐BFO‐optimized partitioned carbon fiber mid‐floor achieves a 46.7% weight reduction and significantly improves the bending and torsional stiffness and modal performance of the body‐in‐white. ABSTRACT To improve the performance of the body‐in‐white (BIW) and achieve automotive lightweighting, a balanced approach across materials, techniques, and ...

Study on Deformation Law of Crossing Layer Drilling Superimposed Floor Roadway

Energy Science &Engineering, Volume 14, Issue 6, Page 2752-2771, June 2026.
Based on deformation law of crossing layer drilling superimposed floor roadway, low dip angle drilling is particularly susceptible to complications such as borehole blockage and collapse. ABSTRACT Floor extraction roadway crossing layer drilling is a pivotal strategy for gas control in areas prone to coal and gas outbursts.

Interpretable Tree‐Based Models for Predicting Short‐Term Rockburst Risk Considering Multiple Factors

Energy Science &Engineering, Volume 14, Issue 6, Page 2941-2960, June 2026.
Interpretable tree‐based models integrate microseismic, geological, and mining indicators to predict short‐term rockburst risk. SHAP analysis reveals the dominant role of energy‐related features and clarifies nonlinear factor interactions, enabling transparent and reliable early‐warning in deep coal mines.
