Abstract
A method for preparing stampable composites of poly(arylene sulfide) compositions that are radio frequency energy sensitive and reinforced with fibrous or filamentous mat; the stampable composites prepared thereby; a method for preparing a laminate with metal sheet and fiber mat reinforced poly(arylene sulfide) in which the poly(arylene sulfide) is sensitive to radio frequency energy; a bonded laminate produced thereby; stamped objects produced from the composites and/or laminates.
Claims41
A porous composite of fibrous reinforcing mat surrounded by a discontinuous matrix forming a fused coating of the fibrous mat said matrix comprising poly(arylene sulfide) and a radio frequency energy sensitizer.
A non-porous composite of fibrous reinforcing mat surrounded by a continuous matrix forming a fused coating of the fibrous mat said matrix comprising poly(arylene sulfide) and a radio frequency energy sensitizer.
A porous composite of fibrous reinforcing mat surrounded by a continuous matrix forming a fused coating of the fibrous mat said matrix comprising poly(arylene sulfide) and a radio frequency energy sensitizer.
A method for preparing a porous composite of fibrous reinforcing mat surrounded by a discontinuous matrix forming a fused coating of the fibrous mat said matrix comprising poly(arylene sulfide) and radio frequency energy sensitizer said method comprising:
- (a) impregnating a mat of fibrous reinforcing material with an admixture comprising poly(arylene sulfide) powder admixed with an amount of a radio frequency energy sensitizing composition sufficient to produce an admixture sensitive to melting using radio frequency energy, said admixture present in an amount that on treatment with radio frequency energy produces a discontinuous matrix,
- (b) subjecting said mat impregnated with said admixture to sufficient radio frequency energy to melt said admixture thereby forming a discontinuous matrix of sensitized poly(arylene sulfide) surrounding said reinforcing material with a fused coating, and
- (c) cooling said matrix coated with poly(arylene sulfide) to produce a reinforced composite.
