  • composition
  • A method of producing a curable prepreg which comprises (i) sandwiching a multi-ply fabric layer comprising at least two superposed sheets of woven reinforcing fabric between solid films of a curable resin composition and (ii) heating the resulting sandwich under pressure so that the resin composition impregnates the sheets of woven reinforcing fabric to form a coherent curable structure.

  • 7. A method according to claim 1, in which the multi-ply fabric is laid on a solid film of curable resin composition, a further film of curable resin composition is laid on top of the multi-ply fabric and the resulting assembly is heated underpressure. (patentgenius.com)
  • 8. A method according to claim 1, in which the prepreg is made continuously by applying continuous solid films of curable resin composition simultaneously to each face of the multi-ply fabric and passing the resulting sandwich between heatedrollers so that the resin composition impregnates the multi-ply fabric to form a coherent curable structure.

  • C. so that the resin composition impregnates the fabric. (patentgenius.com)
  • 13. A curable prepreg consisting essentially of a multi-ply fabric layer, which comprises at least two superposed sheets of woven reinforcing fabric, impregnated by, and contained within a sheet matrix of, a solid curable resin composition inwhich the superposed sheets of woven fabric are held together by a retaining means which inhibits movement of the sheets in relation to each other.

  • For many years, fibre reinforced resin products used in the aerospace and allied industries have been produced by curing a sheet, or in the case of laminates two or more superposed sheets, of curable fibre reinforced prepreg, i.e. fibrousreinforcing material impregnated by, and within a matrix of, a solid curable resin composition.

  • Polymers used in the composition of composite resins may absorb water and chemicals from the oral environment (sorption) and may release some of their own components (solubility) 1,12 . (scielo.br)
  • acrylic
  • In this technique, a transparent acrylic resin matrix is fabricated before preparation of the facial surface of the tooth, to allow the adequate reproduction of contour, shape, and surface texture originally exhibited by the tooth. (ebscohost.com)
  • Acrylic resin, in particular the methyl methacrylate type of synthetic resin, produces acrylic glass (also called PMMA, Lucite, Plexiglass), which is not a glass but a plastic polymer that is transparent, and very hard. (wikipedia.org)
  • polymer
  • This method is very important in that both of the chain polymer and core polymer are freely selected from various resins. (google.com)
  • In the recent years, researchers have made efforts on the surface modification to increase the properties of the polymer matrix composites [ 7 - 10 ]. (hindawi.com)
  • The synthetic resin for such processes is a monomer for making a plastic thermosetting polymer. (wikipedia.org)
  • Single-monomer resins may be used in the process, which form homopolymers (polymers containing only one type of polymer). (wikipedia.org)
  • Synthetic
  • Bond Strength Variation of Synthetic Resin Teeth in Dentures. (ebscohost.com)
  • Resin casting is a method of plastic casting where a mold is filled with a liquid synthetic resin, which then hardens. (wikipedia.org)
  • After the mold has been made, a synthetic resin - such as polyurethane or epoxy - mixed with a curing agent, is poured into each mold cavity. (wikipedia.org)
  • Surfaces
  • Statistically significant differences were found between U and L surfaces of each composite shade-IT combination (p=0.0001) and among the ITs of same shade-surface combination (p=0.0001), except between groups A1-20U and A1-40U, confirming the study hypothesis 1 and partially rejecting the hypothesis 2.

  • adequately
  • it was discontinued due to this requirement, as well as the fact that the shorter wavelengths of UV lighting used did not penetrate deeply enough into the resin to adequately cure it. (wikipedia.org)
  • cavity
  • In dentistry, an inlay is usually an indirect restoration (filling) consisting of a solid substance (as gold, porcelain or less often a cured composite resin) fitted to a cavity in a tooth and cemented into place. (wikipedia.org)
  • teeth
  • A complete oral examination revealed no significant problems or pathosis, other than her unsightly old single resin restoration wedged between teeth Nos. (dentalproductshopper.com)
  • commonly
  • The molds are commonly half-divided (like the hollowed chocolate Easter eggs with candy inside) and a release agent may be used to make removal of the hardened/set resin from the mold easier. (wikipedia.org)
  • thorough
  • While the LED curing light is a huge step forward from the initial curing light offerings, refinements and new technologies are continually being developed with the goal of quicker and more thorough curing of resin composites. (wikipedia.org)
  • mold
  • The simplest method is gravity casting where the resin is poured into the mold and pulled down into all the parts by gravity. (wikipedia.org)
  • Pressure and/or centrifugal force can be used to help push the liquid resin into all details of the mold. (wikipedia.org)
  • time
  • Another study detected an increased survival time of composite resin inlays but it was rated to not necessarily justify their bigger effort and price. (wikipedia.org)
  • fracture
  • This in vitro study determined the fracture toughness of four classes of resin using wet and dry test environments, following 48 hours of wet storage. (ebscohost.com)
  • produce
  • Resin casting is used to produce collectible and customized toys and figures like designer toys, garage kits and ball-jointed dolls, as well as scale models, either individual parts or entire models of objects like trains, aircraft or ships. (wikipedia.org)
  • The low initial investment cost of resin casting means that individual hobbyists can produce small runs for their own use, such as customization, while companies can use it to produce small runs for public sale. (wikipedia.org)
  • There is some evidence that, when placed correctly, composite resin can produce high success rates. (wikipedia.org)
  • light
  • As light passes through the bulk of the composite resin, it is absorbed, dispersed and attenuated, decreasing the irradiance and curing effectiveness (3), consequently, the surface layer close to the light source is better polymerized than the layers far from it. (scielo.br)
  • Composite discs were formed in Teflon molds and light-activated according to the manufacturers' recommended procedures. (umich.edu)
