Postponed differentiation of reinforced composites

A laminate comprising:

• a first fabric formed from a plurality of fibers having at least one fabric formed from a plurality of fibers having a sizing composition and a single first chemical treatment disposed thereon, wherein the first sizing composition includes a film former and a coupling agent, the first fabric having a first side and a second side;
• said first chemical treatment being coated on the first side of the first fabric, wherein the first chemical treatment is present on the first fabric in an amount from 1 weight percent to 20 weight percent and the first chemical treatment consists of one or more of a first polyamide having a melting point less than 250° C., a first reactive compound selected from a primary amine, primary amide, styrene-maleic anhydride, and mixtures thereof;
• a first thermoplastic matrix material coated on the first chemical treatment, wherein the first sizing composition is not compatible with said first thermoplastic matrix material and the first chemical treatment increases the compatibility between the first sizing composition and the first thermoplastic matrix material;
• a second fabric formed from a plurality of fibers having a second sizing composition at least one fabric formed from a plurality of fibers having a sizing composition and a single second chemical treatment disposed thereon, wherein the second sizing composition includes a film former and a coupling agent, the second fabric having a first side and a second side, wherein the second side of the second fabric is laminated to the first thermoplastic matrix material;
• said second chemical treatment being coated on the first side of the second fabric, wherein the second chemical treatment is present on the second fabric in an amount from 1 weight percent to 20 weight percent and the second chemical treatment consists of one or more of a second polyamide having a melting point less than 250° C., a second reactive compound selected from a primary amine, primary amide, styrene-maleic anhydride, and mixtures thereof;
• and
• a second thermoplastic matrix material coated on the second chemical treatment, wherein the second sizing composition is not compatible with said second thermoplastic matrix material and the second chemical treatment increases the compatibility between the second sizing composition and the second thermoplastic matrix material.

A reinforced composite comprising:

• at least one fabric formed from a plurality of fibers having a sizing composition and a single chemical treatment disposed thereon;
• said chemical treatment being coated on a surface of the fabric, wherein the chemical treatment is present on the fabric in an amount from 1 weight percent to 20 weight percent and the chemical treatment consists of one or more of the group consisting of polyamidoamine, polyamine, 4,4′-methylenebis-(cyclohexylamine), polyoxypropylene diamine, triethyleneglycol diamine, trimethylopropane-polyoxypropylene triamine, bis(2-aminopropyl)ether, aminopropylvinyl ether, and polybutadiene diamine;
• and
• a thermoplastic matrix material, wherein the sizing composition is not compatible with the thermoplastic matrix material.
