Experimental Comparative Analysis of Hole‐Making Strategies and Cutting Parameters on Flexural Properties and Induced Delamination in S2 Glass and Basalt Fiber‐Reinforced Polymers

open access: yesPolymer Composites, EarlyView.
Hole‐making strategy and machining parameters influence delamination and hole quality in S2‐glass and basalt FRP composites, which subsequently affet flexural performance. Improved hole integrity leads to enhanced structural performance during three‐point bending.

Nonwoven rCF/PA6 Thermoplastic Composites: Hybrid Commingled Fibers vs. Powder Impregnation—Effects on Microstructure and Mechanical Properties

open access: yesPolymer Composites, EarlyView.
Comparison of powder impregnation and hybrid commingled non‐wovens for PA6/rCF nonwoven composites. The two‐step powder route gives lower voids and higher properties, while the single‐step hybrid route is limited by precursor inhomogeneity and high void content.

Analysis of the Crashworthiness of Novel Flax‐Fiber Hybrid Reinforced Three‐Dimensional Woven Composites

open access: yesPolymer Composites, EarlyView.
Through‐thickness binder yarns in tailored three‐dimensional woven flax‐fiber composites stabilize damage propagation and promote progressive crushing, enhancing crashworthiness and energy absorption. ABSTRACT This study investigates the impact crashworthiness performance of flax‐fiber reinforced three‐dimensional (3D) composites through a ...
