VERFAHREN ZUR HERSTELLUNG EINES FASERVERSTÄRKTEN PRODUKTES AUF EPOXIDHARZBASIS |
摘要 |
A method for the production of fibre-reinforced, epoxy resin products by resin-transfer moulding involves using an epoxy resin/aromatic diamine mixture containing 2-25 wt% crosslinkable polysiloxane-based elastomer particles with an average particle diameter of 1-5 microns and a mol. wt. of 1000-100000, surface-modified with groups which react with epoxy resin. A method for the production of fibre-reinforced, epoxy resin-based products involves (a) optionally preforming the fibre material, (b) placing the material in a mould (optionally precoated with release agent) and closing the mould to shape the material, (c) injecting under normal pressure a mixture of (i) 50-70 parts by weight (pts. wt.) epoxy resin, (ii) 25-50 pts. wt. aromatic diamine, (iii) 2-25 pts. wt. crosslinkable elastomer particles based on polyorganosiloxanes with an average particle diameter (d50) of 1-5 microns and an average mol. wt. of 1000-100000, surface-modified with groups which are reactive towards epoxy resin and (iv) 0.05-2 pts. wt. other conventional additives, (d) crosslinking the mixture, optionally by heating the mould and (e) demoulding the product. |
