METHOD OF HYDROABRASIVE CUTTING OF HONEYCOMB AND HONEYCOMB PANELS MADE OF POLYMER COMPOSITE MATERIALS Russian patent published in 1997 - IPC

FIELD: cutting tools. SUBSTANCE: method of cutting with hydroabrasive jet includes directing high- pressure working fluid jet and abrasive particles onto honeycomb surface to be treated, honeycomb having been preliminarily filled along supposed cut line with water-resistant polymer-glue composition with abrasive in amount 20-70% based on total filler volume. The same composition is applied onto surface of upper panel envelop along supposed cut line. As filler, a composition can be utilized containing (in weight parts): epoxide resin, 55-61; product of condensation of dimerized acid methyl esters of acids of vegetable oils and polyethylenepolyamines, 38.3-44.3; 1-aminohexamethylene-6- amonomethylenetriethoxysilane, 0.5-0.6; diethylaminomethyltriethoxysilane, 0.1-0.2. As abrasive, glass microspheres and white fused corundum are used. EFFECT: facilitated cutting procedure. 3 cl, 1 dwg
