Abstract

A fiber reinforced composite prepreg includes a prepreg containing reinforcing fiber and an uncured matrix resin, and a thermoplastic urethane elastomer film laid on the prepreg. A fiber reinforced composite laminate is formed by subjecting the fiber reinforced composite prepreg to hot pressing techniques. The thermoplastic urethane elastomer film enhances the bonding strength between the laminate and other materials bonded thereto.

Claims

exact text as granted — not AI-modified
I claim:  
     
         1 . A fiber reinforced composite prepreg comprising: 
 a prepreg containing reinforcing fiber and an uncured matrix resin; and    a thermoplastic urethane elastomer film laid on said prepreg.    
     
     
         2 . The fiber reinforced composite prepreg of  claim 1 , wherein said uncured matrix resin is made from an epoxy resin composition.  
     
     
         3 . A fiber reinforced composite laminate comprising: 
 a laminate that is formed by hot pressing a prepreg together with a thermoplastic urethane elastomer film, said prepreg containing reinforcing fiber and an uncured matrix resin, said matrix resin being cured and being bonded to said thermoplastic urethane elastomer film during the hot pressing.    
     
     
         4 . The fiber reinforced composite laminate of  claim 3 , wherein said uncured matrix resin is made from an epoxy resin composition.
