Appl. No.:

12/887287

Inventors:

James Francis Pratte - Wilmington DE, US
Scott A. Rogers - Placentia CA, US
Dominique Ponsolle - Winona MN, US

Assignee:

Cytec Technology Corp. - Wilmington DE

International Classification:

B32B 27/04

US Classification:

4283007, 4282991, 4282994, 4282997, 4274071

Abstract:

Thermoplastic composites having a core composite layer including a fibrous substrate and one or more high performance polymer, and a surface layer polymer applied to at least one surface of the core composite layer, which forms a polymer blend with the high performance polymer thereby imparting improved toughness and processing times, and methods for making and using same, are provided herein.

Appl. No.:

13/413466

Inventors:

James F. Pratte - Wilmington DE, US
Scott A. Rogers - Placentia CA, US
Dominique Ponsolle - Winona MN, US

Assignee:

CYTEC TECHNOLOGY CORP. - Wilmington DE

International Classification:

B32B 37/02

US Classification:

156182

Abstract:

A plurality of thermoplastic composite structures are laminated to each other in a lay-up arrangement to form a laminate. Each thermoplastic composite structure is composed of a core composite layer and a surface layer polymer applied to opposing surfaces of the core composite layer. The core composite layer is composed of a fibrous substrate and one or more high performance polymers, which crystallize at a faster rate than the surface layer polymer.

Abstract:

Some embodiments herein are directed to a thermoplastic composite structure having at least one structural layer of fiber-reinforced thermoplastic resin and at least one toughening layer adjacent to a surface of the structural layer. The toughening layer is configured to create an interlaminar region in a composite laminate and may take the form of a polymer film, a woven or non-woven fibrous material free particles, a polymer layer or non-woven veil with toughening particles dispersed therein, metal mesh or toll.

International Classification:

C08G 7310
C08G 6928
B32B 2700

US Classification:

528170

Abstract:

Polyimide polymers from 3,4,3',4'-biphenyltetracarboxylic dianhydride and 3,4,3',4'-benzophenonetetracarboxylic dianhydride and a diamine such as p-phenylenediamine exhibit a high glass transition temperature, high thermal oxidative stability and low moisture regain, useful for structural applications.

Abstract:

Surface-treated polymeric particles which are dispersible in water or an aqueous solution without the aid of any surfactant. Surface treatment of hydrophobic polymeric particles is carried out to increase the surface energy and to render the surfaces of the particles hydrophilic, thereby eliminating the need for a surfactant to disperse the polymeric particles in water or an aqueous solution. As such, a surfactantless slurry can be formed from the surface-treated particles for the fabrication of fiber-reinforced thermoplastic composite structures.
