Woodceramics, which are made of wood or wood-based materials impregnated by thermosetting resins
and then carbonized at a high temperature, are porous carbon materials, the properties of which vary according to manufacturing conditions.
Heat and steam then are injected into the pipe to activate the thermosetting resins
, resulting in a new structural pipe inside the original pipe.
This volume is occupied by a thermosetting resin
of density [rho], specific heat [C.sub.p], thermal conductivity k, and conversion enthalpy [Delta][H.sub.T].
National Liner consists of a non-woven, needled polyester felt liner saturated with a thermosetting resin
system designed specifically for the environmental conditions of the rehabilitation project.
It comprises a thermoplastic polyimide obtained by reacting a diamine component comprising a diamine represented by the following formula (1) with a tetracarboxylic acid dianhydride, and a thermosetting resin
contained in the ratio of from 1 to 200 weight parts, based on 100 weight parts of the thermoplastic polyimide.
An abrasive article is provided that includes at least one binder system formed from a polymeric additive and a thermosetting resin
. The polymeric additive includes a polymeric backbone having substituents attached thereto, wherein the substituents include at least one urethane linked nitrogen bonded side chain having about 5 carbon atoms or more and a terminal methyl group and at least one oxygen linked water solubilizing group.
The materials are available as copper-clad laminates or prepregs in a woven-fiberglass-reinforced, low polarity thermosetting resin
system modified with a proprietary microdisperse ceramic.
The process uses a custom-manufactured non-woven felt tube impregnated with a polyester thermosetting resin
. The tube is inserted into the damaged section of pipe, usually through an existing manhole, and installers use gravity and water pressure to propel the tube through the host pipe, inverting it while pressing it radially outward into intimate contact with the walls of the existing pipe.
However, cycle times for the production of car parts are much faster and the thermosetting resin
must therefore cure in only a few minutes, not a few hours.
Kotaki, Wang, and He have developed a conductive material consisting of a curable liquid thermosetting resin
mixed with conductive nanofibers such as carbon nanotubes, carbon nanofibers, metallic nanofibers, or nonconductive nanofibers with an electrically conductive coating, plus a particulate filler.
It is known that the magnitude of the exothermic heat produced during the curing of a thermosetting resin
is usually used to evaluate the controllability of the curing reactions (21).
