Claims
- 1. A matrix resin composition comprising
- a. about 100 parts by weight of a first component which is a two component mixture of approximately equal parts by weight of diglycidyl ether of bisphenol A and an epoxidized dimer of oleic acid;
- b. of about 20 to about 23 parts by weight of a second component of butanediol diglycidyl ether;
- c. of about 20 parts by weight of a third component which is a three component mixture of diaminodiphenylmethane in a ratio of about 65 parts of said diaminodiphenylmethane with about 10 parts by weight of triamines and with about 25 parts by weight of polyamines; and,
- d. of a fourth component of 1,4,6-trioxaspiro[4.4]nonane in parts by weight from about 2 to about 5 to achieve a conversion of said first three compositions of said matrix resin composition from a shrinkable matrix resin composition to an expandable matrix resin composition during polymerization or curing phase of said matrix resin composition.
- 2. The matrix resin composition of claim 1 wherein said second component is present in an amount of about 23 parts by weight and wherein said fourth composition of said 1,4,6-trioxaspiro[4.4]nonane is present in an amount of about 2 parts by weight.
- 3. The matrix resin of claim 1 wherein said second component of butanediol diglycidyl either is present in an amount of about 20 parts by weight and wherein said fourth composition of said 1,4,6-trioxaspiro[4.4]nonane is present in an amount of about 5 parts by weight.
