The article discusses the optimum temperatures at which the barrel zones, die zone and adapter zone should be set to achieve maximum performance and reduce wear to polymer melt. Continue reading to …
Curing is a chemical process employed in polymer chemistry and process engineering that produces the toughening or hardening of a polymer material by cross-linking of polymer chains. Even if it is strongly associated with the production of thermosetting polymers, the term "curing" can be used for all … See more During the curing process, single monomers and oligomers, mixed with or without a curing agent, react to form a tridimensional polymeric network. In the very first part of the reaction branches of molecules with … See more In the case of concrete, curing entails the formation of silicate crosslinks. The process is not induced by additives. In many cases, the resin is provided as a solution or mixture … See more • Vulcanization • Cross-link See more Epoxy resins are typically cured by the use of additives, often called hardeners. Polyamines are often used. The amine groups ring-open the epoxide rings. In rubber, the curing is also induced by the addition of a crosslinker. The resulting process is called See more Cure monitoring is, for example, an essential component for the control of the manufacturing process of composite materials. The material, initially liquid, at the end of the … See more WebAug 24, 2024 · The corrosion of polymer matrix composites is additionally plagued by two different factors: the nature of the laminate and, within the case of thermosetting resins, the cure. Improper or poor cure can adversely impact corrosion resistance, whereas correct cure time and procedures can usually improve corrosion resistance.
WebAdditionally, the surface roughness increased the specific adhesion contact area between the epoxy polymer chains and the titanium substrate. Finally, the simulation found that both the D1002 and D3165 SLJs began failing at the lapping edges due to peeling stresses; the lapping edges were identified as stress concentration points. WebJul 1, 2015 · A typical silane-functional organic polymer features relatively high molecular weight polyether segments terminating in di- or trifunctional alkoxy caps. This polymer morphology places much of the stress experienced by the cured matrix on the highly crosslinked polymer termini, as opposed to the polyether backbone.
WebPolymer stress-strain curve. Stress-strain curves show the response of a material to an applied (usually tensile) stress. They allow important information such as a material's elastic modulus and yield stress to be determined. Accurate knowledge of these parameters is paramount in engineering design. Polymer stress-strain curves are produced by ...
WebJan 22, 2024 · The curing of a thermoset polymer coating, adhesive, or matrix in intimate contact with metal and/or ceramic surface (s) is a common process that introduces residual stresses.
