Abstract
An ablative material comprises a phenolic resin, a polymeric phosphorylated amide, and a number of fillers. The polymeric phosphorylated amide is in the ratio of between 1 and 10 parts of the polymeric phosphorylated amide per 100 parts of phenolic resin or resin solids, by weight.
Claims20
A method comprising:
- adding a phenolic resin to a mixer;
- adding between 1 part and 4.9 parts of a polymeric phosphorylated amide, per 100 parts of the phenolic resin, by weight to the mixer;
- mixing the phenolic resin and the polymeric phosphorylated amide for at least 5 minutes;
- adding a number of fillers to the mixer after mixing the phenolic resin and the polymeric phosphorylated amide for at least 5 minutes;
- and
- mixing the number of fillers, the polymeric phosphorylated amide, and the phenolic resin to form an ablative material.

- adding a number of fillers to the mixer after mixing the phenolic resin and the polymeric phosphorylated amide for at least 5 minutes;
- mixing the number of fillers, the polymeric phosphorylated amide, and the phenolic resin to form an ablative material, wherein incorporation of the polymeric phosphorylated amide:
- increases strain compliance of the ablative material;
- and
- decreases modulus of the ablative material;
- disposing the ablative material in a mold;
- and
- curing the ablative material in the mold.
