Improvements in materials for the manufacture of fiber-reinforced thermosetting resin mouldings
TL;DR: An improved FRP molding material was proposed in this paper where 1.5 to 6.0% of an acid-modified vinyl acetate copolymer was added as a low profile additive.
Patent
Fibre reinforced polyester moulding compositions and their use in car bodywork construction
TL;DR: A curable, unsaturated polyester molding composition containing a mixture of the following components: an ethylenically unsaturated, copolymerisable monomeric compound, a vibration-reducing thermoplastic polymer, a fibrous reinforcing agent and optionally E. thickeners, free-radical formers, inhibitors, fillers, flameproofing agents, lubricants, dyes and/or pigments as discussed by the authors.
Patent
Curable polyester molding compositions having low shrinkage
TL;DR: In this paper, a curable molding composition having low shrinkage was proposed, comprising an unsaturated polyester resin and a thermoplastic polyester made from a cycloaliphatic dicarboxylic acid.
Patent
Method for the fabrication of unsaturated polyester articles without shrinkage
TL;DR: In this article, the reaction injection molding (RIM) was used to mold unsaturated polyester resins containing 5 to 50% by weight of a saturated polyester.
Patent
Curable molding compositions
TL;DR: In this paper, the application relates to molded compositions based on unsaturated polyester resins which can be cured with low shrinkage and contain saturated, thermoplastic polyesters and a polyoxyalkylene, in particular an ethylene oxide-propylene oxide block copolymer.
