Toughened Thermosetting Structural Materials

US Patent:
5242748, Sep 7, 1993
Filed:
Jan 4, 1989
Appl. No.:
7/293236
Inventors:
Thomas Folda - Neuleiningen, DE
Jack D. Boyd - Westminster CA
Helmut Tesch - Birkenheide, DE
Thomas Weber - Ludwigshafen, DE
Hans G. Recker - Irvine CA
Assignee:
BASF Aktiengesellschaft - Ludwigshafen
International Classification:
C08L 6300
C08F28304
B32B 2700
US Classification:
428272
Abstract:
The incorporation of 2 to 25. mu. m particles of a limited class of polyimides having appreciable nonaromatic character into heat curable epoxy resin systems significantly increases the toughness of such systems without loss of other desirable properties. These toughened epoxy resin systems are useful in preparing carbon fiber reinforced composites having compression strength after impact (CAI) of greater than 45 Ksi after a 1500 in-lb/in impact.

Toughened, Fiber-Reinforced Thermosetting Resin Matrix Prepregs And Composites Made Therefrom

US Patent:
5627222, May 6, 1997
Filed:
Jan 9, 1995
Appl. No.:
8/370338
Inventors:
Hans G. Recker - Irvine CA
Volker Altsaedt - Gernsheim, DE
Helmut Tesch - Roedersheim/Gronau, DE
Thomas Weber - Ludwigshafen, DE
Assignee:
Cytec Technology Corp. - Wilmington DE
International Classification:
C08G 7310
C08J 524
US Classification:
523400
Abstract:
The subject invention pertains to toughened thermosetting resin systems useful as structural adhesives and as matrix resins for thermosetting fiber-reinforced prepregs. These toughened resins employ a most minor amount of functionalized elastomeric particles having a T. sub. g of 10. degree. C. or below dispersed in a thermosetting base resin system.

Toughened Thermosetting Structural Materials

US Patent:
5605745, Feb 25, 1997
Filed:
Dec 29, 1994
Appl. No.:
8/366392
Inventors:
Hans G. Recker - Irvine CA
J. Timothy Hartness - Tega Cay SC
Thomas Folda - Neuleiningen, DE
Helmut Tesch - Birkenheide, DE
Thomas Weber - Ludwigshafen, DE
Jack D. Boyd - Westminster CA
Assignee:
Cytec Technology Corp. - Wilmington DE
International Classification:
B32B 516
US Classification:
442175
Abstract:
The incorporation of 2 to 35. mu. m particles of a differentially soluble engineering thermoplastic into heat curable epoxy resin systems significantly increases the toughness of such systems without loss of other desirable properties. These toughened epoxy resin systems are useful in preparing carbon fiber reinforced composites having compression strength after impact (CAI) of greater than 45. Ksi 310 MPa after a 1500 in-lb/in impact.

Bismaleimide Resin Systems Toughened By Addition Of Preformed Functionalized Low T.sub.g Elastomer Particles

US Patent:
5532296, Jul 2, 1996
Filed:
Sep 24, 1993
Appl. No.:
8/126012
Inventors:
Hans G. Recker - Irvine CA
Helmut Tesch - Roedersheim/Gronau, DE
Thomas Weber - Ludwigshafen, DE
Volker Altstaedt - Gernsheim, DE
Jack D. Boyd - Westminster CA
Assignee:
Cytec Technology Corp. - Wilmington DE
International Classification:
C08G 7310
C08J 524
US Classification:
523400
Abstract:
Bismaleimide resin systems and fiber reinforced prepregs prepared therefrom having exceptional toughness are prepared by dispersing into a bismaleimide base resin system preformed functionalized elastomer particles having a T. sub. g of less than 10. degree. C.

Toughening Of Brittle Epoxy Resin Matrices With Functionalized Particulate Elastomers

US Patent:
5464902, Nov 7, 1995
Filed:
Feb 4, 1994
Appl. No.:
8/191686
Inventors:
Hans G. Recker - Irvine CA
Assignee:
Cytec Technology Corp. - Wilmington DE
International Classification:
C08F 800
US Classification:
525119
Abstract:
Relatively brittle epoxy resin systems which may be employed as structural film adhesives and matrix resins for fiber-reinforced prepregs are toughened against impact-induced damage by the addition of minor quantities of functionalized elastomer particles having a glass transition temperature of less than 10. degree. C.
