Abstract null null Ultra-high molecular-weight polyethylene (UHMWPE) composites reinforced with Graphene Oxide (GO), Nanodiamonds (ND), and Short Carbon Fibres (SCF) are characterised for their mechanical performance in tensile and short-term creep tests. A methodology to separate and analyse the materials’ viscoelastic (VE) and viscoplastic (VP) responses is applied and evaluated. The results show a clear dependence of the performance on size scale/morphology of the reinforcements. All composit...

Abstract null null This paper presents experimental and numerical investigations in the single-lap, single-bolt joints of carbon fiber reinforced bismaleimides (CF/BMI) composites. In order to guide the engineering design, an optimum configuration of composite joints is determined. Effects of stacking sequence and geometry dimensions on composite joints under tensile loading are discussed to select an optimum configuration. The optimum configuration is validated by the experimental method. Quasi...

Abstract null null UV-polymerizable and UV-crosslinkable pressure-sensitive adhesive acrylic compositions are widely applied for high-quality carrier-free films, one-sided or double-sided self-adhesive tapes. Comprehensive studies of the properties of novel acrylic PSAs for carrier-free films or adhesive tapes were carried out. Solvent-free acrylic pressure-sensitive adhesive layers were UV-crosslinked using various photoreactive crosslinking agents. Polymer content during UV-polymerization, pre...

Abstract null null Carbon fiber reinforced polyethylene composites have garnered recent interest in many industrial fields owing to their inherent benefits of excellent chemical and corrosion resistance, and processing ease. The interfacial strength between polyethylene and carbon fiber has been understudied to this point but it is critical to the performance of these new composite parts. In this study the apparent interfacial shear strength between three differently sized carbon fibers and high...

Abstract null null Effect of CO2-philic additive additives PDMS and co-blowing agent alcohol on dynamic bubble growth behavior of supercritical CO2 assisted polymer foaming process, was investigated by using a visual observation system combined with numeric model. The addition of PDMS in PS accelerates the bubble nucleation and growth rate, and the bubble growth rate decreases with the increase of PDMS molecular weight. The bubble growth of polymer is mainly determined by the effect of PDMS on t...

Abstract null null Thermoplastic overmolding technique is an advanced integrated manufacturing technology to fabricate hybrid fiber reinforced thermoplastic composites (hybrid composites) components in which short fiber reinforced thermoplastics are injected onto the surface of thermoformed continuous fiber reinforced thermoplastic (CFRT) laminate (organosheet). To further clarify the bonding mechanism between the heterogeneous interface of short and continuous glass fiber reinforced thermoplast...

Abstract null null The characterization of materials by means of differential scanning calorimetry (DSC) may contain measurement artefacts originating from the undefined contact area between the material sample and the pan surface. Especially in cases where low thermal conducting materials are investigated, this contact area strongly determines the heat transfer towards the material sample and, thus, the obtained results. As a remedy, the supportive use of heat-transfer agents (HTA) in DSC chara...

Abstract null null Epoxy resins, as a typical class of thermosetting polymers, have widespread industrial applications such as adhesives, coatings, electronic encapsulants, and polymer matrices for advanced composites, owing to their excellent mechanical performance, adhesive capacity, dimensional stability, heat, and chemical resistance. However, conventional epoxy resins cannot be reprocessed, repaired, or recycled due to their permanent crosslinked structures, making it a long-standing challe...

Abstract null null The morphology, size and surface roughness of the nucleating agent significantly affect the nucleation effect for foaming in the polymer. In this work, four nucleating agents with different morphologies, namely DE, MS, OMMT and β- CD as heterogeneous nucleation agents were selected for a polypropylene (PP) foaming injection molding process to explore nucleation mechanism. A theoretical assumption (cavity nucleation) in polymer foaming had been put forward about how to enhance ...

Abstract null null High-performance PBS films can be prepared by the melt-stretching method. The effect of the melt-drawing ratio (MDR) on the mechanical properties and microstructure of PBS cast films prepared by melt-stretching is studied in this paper. The elastic modulus, tensile stress, and strain hardening increase with increasing MDR. With an MDR of 25–50, the crystalline morphology changes from deformed spherulites to row-nucleated lamellar structure. The lateral size and orientation of ...
