Summary: A numerical model based on crack phase field analysis was used to investigate the quasi-static fracture process in interpenetrating phase composites (IPCs). The study found that tougher and stiffer tougheners result in more fracture in the brittle phase, but less fracture in the toughening phase, leading to a competition between increasing breakage in the brittle phase and declining breakage in the toughening phase. The study also identified various crack propagation patterns and compared fracture in different microstructures.

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: Researchers investigated the effects of replacing Portland cement with supplementary cementitious materials (SCM) on the durability of Ensete ventricosum (Ev) fibres in cementitious matrices. The flexure tests showed that composites with 100% Portland cement matrix lost ductility and strength after 25 wet-dry cycles, while ternary matrices of 70% FA and 10% MK exhibited minimal degradation. Partial replacement of Portland cement by SCMs can reduce the degradation of natural fibres in cement-based composites.

Summary: The inclusion of superabsorbent polymers (SAPs) is increasingly attractive to promote the self-healing ability of cementitious materials and reduce manual repair costs. Ultrasonic monitoring is used for non-destructive evaluation to determine the effectiveness and compare the healing capacity of different mixtures. However, previous studies mainly focused on mortars without large aggregates, so monitoring and comparing the self-healing of concrete and mortar were conducted. Ultrasonic surface wave monitoring shows the potential to evaluate crack closure and the effects of different SAPs.

The governing equation for interface forces and moments is obtained under plane strain assumptions, considering extension-bending coupling phenomena and residual hygrothermal stresses. The interface forces and moments are included in a novel generalization of the J-integral to estimate the Energy Release Rate (ERR). The analytical results of ERR and mode mixity show excellent agreement with Finite Element models for a Double Cantilever Beam test of a generally layered fibre metal laminate, utilizing the Cohesive Zone Method (CZM) and the Virtual Crack Closure Technique (VCCT).

Summary: This study evaluates the closure of cracks in cementitious mixtures with and without superabsorbent polymers using ultrasound measurements. By sending ultrasonic waves through the cracks, information on both the sound material and the healing products formed within the cracks is obtained. The healing process is promoted by wet-dry curing cycles and monitored for 14 days. Ultrasound was found to be sensitive to the closure of cracks, as confirmed by microscopic analysis of the reduction in crack width opening.

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.
