US Patent:

47787163, Oct 18, 1988
Filed:

Mar 26, 1987
Appl. No.:

7/030475
Inventors:

Bradley S. Thorfinnson - Orange CA
Thomas J. Folda - Placentia CA
Assignee:

BASF Corporation - Parsippany NJ
International Classification:

B32B 502
US Classification:

428236
Abstract:

Inclusion of minor amounts of predominately amorphous silica microfibers into thermosetting matrix resins allow manufacture of prepregs which produce toughened composites resistant to impact damage without the loss of modulus normally associated with toughened resin systems.
