Summary: High-performance polymer fibres have excellent tensile and physical properties but poor compressive performance, which limits their use in structural composite applications. Testing unidirectional thermoset composites made with three types of polymer fibres in shear-loaded compression confirmed their poor compressive performance despite good fibre alignment, low porosity, and decent interfacial adhesion. The collapse of the fibres rather than microbuckling was identified as the main cause. The finite element model developed predicted that the short gauge lengths needed to avoid buckling led to significant strain concentrations due to the grips, resulting in underestimation of the compressive modulus and potentially the rest of the compressive stress in the stress-strain diagram.

Summary: Thermoset materials and their composites have important applications in aircraft, wind turbines, and constructions, and the interest in their recycling is growing. Successful recovery and valorization of these materials require degradation of their structures and recovery of valuable components. This mini-review focuses on the formulation and recovery methods of innovative thermoset materials with built-in recyclability. The aim is to provide an overview of thermoset recycling and commonly used composites, as well as novel formulating strategies. This review is also a valuable guide for students and technicians in polymer production and recycling.

Summary: The study reveals that the glass transition of toughening particles has different effects on the interlaminar G12 and G13 in two ways, by changing microstructural characteristics in the pre-gelation stage and reducing shear modulus in the post-gelation stage.

Summary: This paper investigates the interlaminar bond strength of laser in-situ consolidation CF/PEEK thermoplastic composites. The results show that porosity significantly affects the interlaminar shear strength, while there is no correlation between crystallinity and interlaminar shear strength. The interlaminar shear strength in the heated tool in-situ consolidation group is significantly higher than the constant pressure in-situ consolidation group.

Summary: This material demonstrates a reversible temperature-triggered self-healing mechanism using furanic pendant moiety and bismaleimide with Diels-Alder reaction, along with a reversible electrically conductive polymer network achieved by adding reduced graphene oxide. Additionally, the electrical conductivity is activated at temperatures higher than 100 degrees C, showing potential applications as electronic switches in self-healing soft devices.

Summary: This study explores the use of recycled thermosetting polymer waste (RTPW) in the fabrication of composites with high-density polyethylene (HDPE). The results show that incorporating RTPW enhances the thermal behavior of the HDPE composites, improving melt flow index, heat deflection temperature, and VICAT softening temperature while minimally affecting the crystallinity of HDPE.

Summary: It is shown that discrete in-situ consolidation (DISC) can significantly reduce porosity and increase mechanical performance in continuous fiber-reinforced polymer composites deposited by fused filament fabrication (FFF). By alternating between material deposition and DISC, well-consolidated material can be built up layer-by-layer. DISC technology is also demonstrated to be suitable for manufacturing geometrically complex forms.

Summary: This study aimed to revisit the effect of porosity in fiberglass composites and tried different methods to create controlled voids. The water spray method proved to produce significantly different levels of porosity, but required drying after curing. Voids influenced the horizontal propagation of cracks between layers, but did not act as initiation sites for failure.

Summary: The high dimensional accuracy of thermoset composite parts poses a challenge for manufacturers in the aeronautical industry, requiring a deep understanding of cure behavior to prevent shape deformations caused by internal stresses. Experimental investigations using PvT-HADDOC reveal higher coefficients of thermal expansion along the thickness direction in liquid and cured states. The orthotropic behavior of the IMA/M21 system is attributed to the presence of interleaf layers of resin within the prepreg plies.
