Abstract
A substrate and method for providing a thermoplastic composite having a fiberglass mat embedded within a thermoplastic polymer. The characteristics of the fiberglass mat combined with a thermal compression bonding method allow for a substantially improved and desirable thermal expansion coefficient over conventionally filled thermoplastic substrates or other fiberglass reinforced thermoplastics.
Claims20
A substrate comprising:
- a thermoplastic composite having a fiberglass mat embedded in a thermoplastic resin, wherein the fiberglass mat has a basis weight of 76 to 500 g/m2 and about 20 to about 3000 fiberglass intersections per cm2, and wherein the thermoplastic composite possesses (i) a Thermal Expansion Coefficient of ⅓ or less than that of a substrate derived from a neat embodiment of the thermoplastic resin, or (ii) a Thermal Expansion Coefficient of 50*10−6 m/(m*° C.) or lower.
An article comprising a substrate derived from thermal compression bonding a thermoplastic resin with a fiberglass mat and optionally one or more fillers, wherein the fiberglass mat has a basis weight of 76 to 1250 g/m2 and about 20 to about 3000 fiberglass intersections per cm2, and wherein the thermoplastic composite possesses a Thermal Expansion Coefficient of ⅓ or less than that of a substrate derived from a neat embodiment of the thermoplastic resin, or (ii) a Thermal Expansion Coefficient of 50*10−6 m/(m*° C.) or lower.
A method comprising:
- (a) scattering a thermoplastic resin with optionally one or more fillers onto a fiberglass mat positioned on a first rotating belt, wherein the fiberglass mat has a weight of at least 76 up to 1250 g/m2 and about 20 to about 3000 fiberglass intersections per cm2 (b) thermal compression bonding the thermoplastic resin with optionally one or more fillers and the fiberglass mat between the first rotating belt with a second rotating belt to form a substrate, wherein the substrate possesses (i) a Thermal Expansion Coefficient of ⅓ or less than that of a substrate derived from a neat embodiment of the thermoplastic resin, or (ii) a Thermal Expansion Coefficient of 50*10−6 m/(m*° C.) or lower.
