Abstract: A low density coring material is described. In one embodiment, the low density coring material consists essentially of: about 40 to about 80 wt % resin; 0 to about 50 wt % monomer; 0 to about 5 wt % dispersion aid; 0 to about 5 wt % accelerator; about 3 to about 7 wt % microspheres; and about 1 to about 5 wt % catalyst; wherein a density of the cured coring material is less than about 5.0 lbs/gal. Composites made using the low density coring material and methods of making composites are also described.
