effect of particulates and fiber reinforcements on the curing behavior of unsaturated polyester resin

the effect of particulates and reinforcement on the curing behavior of unsaturated polyester resin was investigated. also investigated was the effect of surface treatment of particulates on the curing behavior of unsaturated polyester resin. the authors have found that an increase in the surface area, by either increasing the loading of p..

surface treatment technique for aramid fibres

a surface treatment technique based on roughening of the fibre surface is investigated with kevlar (du pont) fibres to promote their bonding to resin matrices. a 20 improvement in the interlaminar shear strength is accompanied by a fibre strength loss of about 15 (author abstract) 6 refs

new strong cement materials: chemically bonded ceramics

new cements developed in recent years have strengths that are greater by an order of magnitude than those of conventional hydraulic cements. these low-temperature materials, whose strengths approach those of many traditional high-temperature ceramics, are termed chemically bonded ceramics. the different routes to generating strong cementi..

composites with metallized reinforcing fibres

with nickel-coated textile structures, in particular woven fabrics, it is possible to increase the interlaminar bond strength of high -performance composites, to improve the reflection and screening behavior in the microwave range and to use corresponding products even as a lightning protection medium. composite structures containing nick..

turning of fibre reinforced thermosetting plastics

the field of application of fibre reinforced plastics has expanded cosiderably in recent years. the mouldings are often machined in order, for example, to obtain highly toleranced working surfaces. a study was thus made of the surface finishes, the cutting forces, the temperatures and the extent of cutting tool wear, when turning various ..

appliance finishing turning to prepaint

except for certain parts subject to high heat end use that need to be coated with porcelain, the entire major appliance industry could convert to prepaint fabrication within 10 years. this prediction from an industry spokesman appears credible, based on the flurry of activity in the appliance industry to change from post-fabrication paint..

lure of molecular computing

the basic principles of molecular computing are described and two approaches are outlined: the biological, which seeks to duplicate the powerful information processing capabilities of biological systems; and the digital, which seeks to create a molecular electronics that would lead to a smaller, faster, less-expensive digital computer wit..

l'aluminium dans l'emballage rigide, semi-rigide, souple $left bracket$ aluminum in rigid, semi rigid and flexible packaging $right bracket$

the advantages of aluminum packaging over other packaging materials are cited. the techniques of fabrication of aluminum packaging are reviewed, including shaping, surface treatment and coatings, and decoration and overprint lacquering. shaping technologies commonly used include stamping, deep drawing, impact extrusion, piercing, swaging,..
