Self-healing was achieved with a dual-microcapsule epoxy-amine chemistry in thermoset epoxy. One capsule contained a modified aliphatic polyamine (EPIKURE 3274) while the second capsule contained a diluted epoxy monomer (EPON 815C). Amine microcapsules were prepared by vacuum infiltration of EPIKURE 3274 into hollow polymeric microcapsules. Epoxy microcapsules were prepared by an in situ polyme...

This paper investigates the mechanical performance and electrical resistivity of a structural adhesive epoxy enhanced using milled carbon fibre (MCF) as well as the bond performance of carbon fibre reinforced polymers (CFRP) and steel adhesively bonded joints using the enhanced epoxy. The epoxy was enhanced using such MCFs with different weight ratios of 1.5%, 3% and 5%. Tensile experiments wer...

The increasing awareness of evposure to traditional paint strippers has prompted a search for altemativeproducts. Onegroup of such alternatives are formulations based on N-Methylpyrolidone (NMPkqn comparing NMP-based paint removers with more volatile products, the primary tradeoffs are stripping speed versus solvent inhalation, and product cost v e m wage cost. NMP-based paint removers work at ...

We have implemented a non-photorealistic rendering system which simulates the placement of paint/pencil/pastel strokes to produce representational artworks from digital images. The system is able to record an image of each paint stroke independent of the overall picture, in addition to some details about each stroke. Working with sets of paint strokes from paintings of different images, we inve...

polysulfide resins,with trade name of  g4 and g112, with short and long chain lengths respectively, were used as reactive modifiers to toughen epoxy resin. the effects of molecular weights of g4 and g112 on impact resistance, dielectric constant, thermal conductivity as well as decomposition  heat and adhesion properties of toughened epoxy were investigated. the impact strength and the dielectr...

BACKGROUND Airborne contact dermatitis (AirbCD) is not uncommon, according to a large number of published case reports and review articles. Epidemiological data on AirbCD based on larger clinical samples have not yet been published. OBJECTIVES To investigate demographic characteristics and patch test reactivity in patients diagnosed with both occupational and non-occupational AirbCD. METHOD...

Epoxy resins are used widely in industry because of their strong adhesive properties, chemical resistance, mechanical toughness and high electrical insulation. Consequently they are often found in adhesives, stabilizers, sealants, varnishes and paints. Epoxy resins consist of bridged diepoxide oligomers of increasing molecular weight and there are various types corresponding to different molecu...

This paper gives a detailed study on the performance of oil paint image filter algorithm with various parameters applied on an image of RGB model. Oil Paint image processing, being very performance hungry, current research tries to find improvement using parallel pattern library. With increasing kernelsize, the processing time of oil paint image filter algorithm increases exponentially.
