Abstract
The invention relates to a composite comprising a thermoplastic resin and a glass fabric that can be used in the form of a linear extrudate as a structural member or as a repair unit. The resin glass fiber composite structural member can be manufactured in an extrusion process. The linear extrudate can have a cross-section of any arbitrary shape or can be a regular geometric shape. The profile is made by first preforming the glass fabric into a useful shape, combining the preform fabric with melt resin and extruding the resin and glass fiber in a useful shape. When contacted with melt resin, the glass fiber becomes intimately contacted with and substantially coated with the melt resin.
Claims16
A profile comprising a thermoplastic resin glass fabric composite, the profile comprising a cross-section shape that departs from planar and includes at least an included angle or an included curve and includes at least one folded fabric edge in the composite wherein the profile has the properties:
- (i) a modulus of elasticity of about 830 kpsi or greater;
- (ii) a coefficient of thermal expansion of about 0.000022 in/in/.degree. F. or less;
- (iii) a shrinkage not to exceed about 0.28%;
- and
- (iv) an impact strength of about 10 in-lbs or greater.
A profile comprising a thermoplastic resin glass fabric composite, the profile comprising a cross-section shape that departs from planar and includes at least an included angle or an included curve and wherein the fabric includes at least one peripheral edge that is folded back onto itself to form a folded fabric edge in the composite, wherein the profile has the properties:
- (i) a modulus of elasticity of about 830 kpsi or greater;
- (ii) a coefficient of thermal expansion of about 0.000022 in/in/.degree. F. or less;
- (iii) a shrinkage not to exceed about 0.28%;
- and
- (iv) an impact resistance of about 10 in-lbs or greater.
