In-situ cure monitoring of epoxy resin systems
… capable of monitoring the cure state of an epoxy/amine resin system. The sensors were of simple construction, consisting of an optical fibre from which the silicone cladding layer had been removed over a short length. This stripped length was embedded into the curing resin system. The sensor …

Modification, curing and flame retardation of epoxy resin networks
… flame retardance of di- and higher functionality epoxy resins were investigated. The influence of curing temperature and time on morphological development and fracture behavior was also studied. Arylamine functionalized poly(arylene ether sulfone)s of controlled molecular weight were synthesized …

Alleviation of stress concentration with analogue reinforcement
… by sandwiching these reinforcements between two epoxy resin plates. Plane specimens, i.e., without reinforcement, were also made of the same epoxy resin for comparison. The stress concentrations at the edge of the hole under uniaxial tension were determined by photoelastic techniques. The …

FAR-END CROSSTALK MODELING AND PREDICTION FOR HIGH-SPEED PCB DESIGN WITH INHOMOGENEOUS DIELECTRIC LAYERS (IDLS)
… layers of the stripline are laminated with epoxy resin and glass bundles. The dielectric permittivity of the epoxy resin and glass bundles are different, which causes the inhomogeneity of the dielectric layers while also increasing the FEXT magnitude. The dielectric of the microstrip in …
