Advancements in UHS research should be matched with new field development studies on natural hydrogen exploration and production.
In this work, a comparative performance study was conducted on glass fibre-reinforced thermoplastic acrylic and thermosetting epoxy laminates produced by vacuum-assisted resin transfer moulding. Mechanical characterisation revealed that the acrylic-based composite had superior transverse tensile strength mode-I fracture toughness to composite, while longitudinal flexural properties short beam shear were found be comparable. Dissimilar damage evolution behaviour observed in both materials...
The manufacturing process of a new generation thermoplastic fibre-metal laminates (TP-FMLs) was investigated. A vacuum assisted resin infusion method used to produce the hybrid laminates. effect various chemical and physical treatments on surface morphology aluminium (Al) alloy sheets bond strength at metal-composite interface examined. wettability, topography composition treated Al were studied by employing contact-angle goniometry, coherence scanning interferometry, profilometry X-ray...
ABSTRACT A comparative study is presented on the fracture toughness of carbon fiber/PEEK composites manufactured by autoclave and laser‐assisted automated tape placement (LATP). Formation a good inter‐laminar bond always concern in ATP due to short time available for intimate contact development polymer healing, yet our double cantilever beam (DCB) tests reveal 60–80% higher Mode I LATP processed specimens than specimens. This magnitude difference was unexpected, so were further examined via...
Thermal reshaping has been employed to simulate the end-of-life reuse of liquid-resin-infused thermoplastic acrylic composite laminates, and associated effects on matrix-dominated mechanical performance microstructure have studied. L-shaped laminates were infused at room temperature subjected 1 or 4 hot-press flattening cycles (25 min 120 °C; 11 bar). Compared original references, up 13% higher transverse flexural strengths measured for reprocessed laminates. Such a scheme may be readily...
Increasing usage of polymer composite materials necessitates the development recyclable alternatives to traditional thermoset matrices or new techniques for recycling these materials. One family promising are room temperature infusible acrylic resins, known commercially as Elium®. If be used in tidal stream energy and shipping sectors, they must able withstand long-term immersion seawater without significant losses mechanical properties. In this study, accelerated ageing is applied...
In this work, end-of-life reuse of continuous fibre-reinforced thermoplastic composites from marine applications has been simulated by thermally reshaping (reprocessing) seawater-aged materials. Specifically, resin-infused, V-shaped glass/acrylic were (60 °C; 170 h) and reprocessed in a heated hydraulic press (120 10 bar). Reprocessing promoted void collapse increased short beam shear strengths. Unaged materials retained 52 % 57 performance flexural strength modulus, (relative to virgin...
The use of thermoplastic composites as a sustainable alternative to thermosets is gaining increasing popularity due their improved recyclability at the end life. fatigue performance glass fibre/acrylic, fibre/acrylic- polyphenylene ether, and fibre/epoxy specimens, under three distinct upper stress levels (R-ratio=0.1; f=5 Hz) was studied. S-N curves were established for these specimens both before after immersing them months in seawater (temperature: 50°C). dry exhibited similar thermoset...
Abstract Fiber‐metal laminates (FMLs) offer the superior characteristics of polymer composites (i.e., light weight, high strength and stiffness) with ductility fracture metals. The bond between two dissimilar materials, composite metal, dictates properties performance FMLs. bonding becomes more critical when matrix is thermoplastic hydrophobic in nature. This work employed a novel technique metal layer using six different combinations organic coatings. flexural, interlaminar shear fiber...
This study exploits the unique attributes of a reactive thermoplastic acrylic resin system (room-temperature liquid-resin infusibility, in-situ polymerisability, and room-temperature weldability) to achieve additive-free mitigation exothermic heat generation during thick laminate production. Additives are typically required when thicknesses exceed 12 mm, but their use often compromises degree polymerisation mechanical performance. An innovative multi-stage manufacturing scheme has been used...
This work demonstrates the use of an engineering thermoplastic, poly(phenylene ether) (PPE) to enhance solvent resistance and thermomechanical properties liquid acrylic resin-based composites by a reactive hybridisation route. Oligomeric PPE with vinyl functionality was employed attain chemical reactivity between two constituents during in-situ polymerisation process. Both unreinforced polymer blends glass fibre-reinforced were studied; physical insights into structure obtained through...
