Summary: The copolymer membrane and AHHFP grafted onto the surface of PBO fibres enhances the interfacial strength and reduces interfacial polarization of the wave-transparent laminated composites. The resulting 6F-PBO@P-GMA fibres/modified cyanate ester composites exhibit higher flexural strength and interlaminar shear strength compared to composites with pristine PBO fibres, with excellent wave-transparency properties at X-band.

Summary: The introduction of hyperbranched structure and fluorine groups in epoxy-preFHBPBO significantly improved the mechanical properties and wave-transparent performance of PBO fibers reinforced BADCy resins composites. The addition of 7 wt% epoxy-preFHBPBO increased the flexural strength and interlaminar shear strength, while reducing dielectric constant and dielectric loss compared to PBO fibers/BADCy composites. Moreover, the volume resistivity and breakdown strength were also enhanced in PBO fibers/FHBPBO-co-BADCy composites.

Summary: This paper investigates the effects of cooling rates on the crystallization behavior, interfacial bonding strength, interlaminar fracture toughness and low-velocity impact performance of carbon fiber reinforced poly(aryl ether ketone) (PAEK) and poly(ether ether ketone) (PEEK) composites. The results show that PAEK has lower crystallinity and smaller crystals compared to PEEK at the same cooling rate. The lower crystallinity and smaller crystals of PAEK contribute to improved matrix ductility and interfacial bonding strength in the composites. Under water cooling conditions, the impact damage area of CF/PAEK is about 71% lower than that of CF/PEEK, while the CAI is about 14% higher.

Summary: This article describes a method that uses Barker-coded thermal wave imaging to identify subsurface anomalies in materials. The proposed methodology can detect smaller defects at a higher depth even on a fully corroded sample of mild steel. Experiments were conducted with various samples and both deep learning and active contour segmentation techniques were used for anomaly detection. The results show that the proposed deep learning method gives better visualization and analysis of subsurface anomalies compared to other approaches.

Summary: This study investigates the effects of fibre concentration on the mechanical response of welded glass-fibre-reinforced polypropylene (GF-PP). Experimental observations reveal a significant reduction in weld ratio, up to 60%, indicating a decreased strength compared to the bulk material. Increasing fibre content in the welded material results in a decrease in stress at break and strain at the maximum stress. The use of DIC technique and X-ray microtomography further confirms the localized strain amplification in the welded zone due to the significant increase in fibre density.

Summary: The vulnerability of natural fibers to heat and fire poses a significant challenge for their substitution of traditional fiber reinforcements in composite materials. Natural fiber/polymer composites (NFCs) are regarded as potential candidates for engineering applications due to their environmental friendliness and low-impact sourcing. Thus, appropriate approaches need to be implemented to enhance the fire safety of NFCs. This review summarizes and discusses the latest understanding of flammability and thermal properties of natural fibers, with a special focus on their interaction with polymer matrix in fire behavior. Additionally, the latest developments in flame-retardant approaches for NFCs are reviewed, covering both flame retardancy and fire structural integrity. Finally, future prospects and perspectives on fire safety of NFCs are proposed, providing insights into further advancements of NFCs.
