Abstract
A reinforced composite substrate made from a composition of about 50 wt. % resin and about 50 wt. % reinforcing fibers, with the reinforcing fibers being 12K tow carbon fiber about one inch long and glass fibers present in a 40:60 ratio by weight is presented. The carbon fibers and glass fibers should be randomly distributed within the reinforced composite substrate. The tensile strength of the reinforced composite substrate is greater than about 170 MPa, the tensile modulus is greater than about 20 GPa, and the specific gravity is less than about 1.60.
Claims21
A reinforced composite substrate comprising
- about 50 wt. % resin;
- and
- about 50 wt. % reinforcing fibers,
- wherein the reinforcing fibers comprise carbon fiber and glass fibers present in a 40:60 ratio by weight, and the carbon fiber comprises 12K tow fiber having an average fiber length of about one inch.
A sheet molding compound comprising
- about 50 weight percent reinforcing fibers comprising about 40 weight percent carbon fibers and about 60 weight percent glass fibers, and
- about 50 weight percent thermosetting resin;
- and
- wherein the carbon fibers comprises 12K tow fiber having an average fiber length of about one inch, the carbon fibers and glass fibers are randomly distributed within the sheet molding compound, the tensile strength of the sheet molding compound is greater than about 170 MPa, the tensile modulus of the sheet molding compound is greater than about 20 GPa, and the specific gravity of the sheet molding compound is less than about 1.60.
A method of forming a composite structural component comprising:
- providing glass fibers of about 1 inch length,
- providing 12 K tow carbon fibers of about 1 inch length,
- forming a mat of randomly distributed glass and carbon fibers,
- contacting a thermosetting resin with the mat to form a resinated mat;
- compacting the resinated mat to form an uncured sheet;
- molding and cutting the uncured sheet to the desired shape and size;
- curing the uncured sheet to form the composite structural component,
- wherein the tensile strength of the composite structural component is greater than about 170 MPa, the tensile modulus of the composite structural component is greater than about 20 GPa, and the specific gravity of the composite structural component is less than about 1.60.
