主权利要求
(IN201747045147)  1. A curable resin composition comprising: (A) a cycloaliphatic epoxy resin containing two or more epoxide groups;  and (B) a tri-functional benzoxazine compound represented by the following structure: Where Ri, R2 and R3 are independently selected from alkyl, cycloalkyl, and aryl, wherein the cycloalkyl and aryl groups are optionally substituted, and where substituted, one or more substituent groups may be present on each cycloalkyl and aryl group;  and R4 is selected from hydrogen, halogen, alkyl and alkenyl. 2. The curable resin composition of claim 1 further comprising: (C) a phenol compound as a catalyst. 3. The curable resin composition of claim 1 or 2 further comprising: (D) a di-functional benzoxazine compound. 4. The curable resin composition of claim 3, wherein the benzoxazine compounds (B) and (D) constitute for more than 50% by weight based on the total weight of the composition. 5. The curable resin composition according to any one of the preceding claims, wherein the tri-functional benzoxazine compound (B) is: 6. The curable resin composition according to any one of the preceding claims, wherein the tri-functional benzoxazine compound (B) is: 7. The curable resin composition according to any one of the preceding claims, wherein the tri-functional benzoxazine compound (B) is: 8. The curable resin composition according to any one of the preceding claims, wherein the cycloaliphatic epoxy resin is 3',4'- epoxycyclohexyl-3,4-epoxycyclohexane carboxylate, represented by the following structure: 9. The curable resin composition according to any one of claims 3 to 8, wherein the di-functional benzoxazine compound (D) is represented by the following structure: Where: Z1 is selected from a direct bond, -C(R3)(R4)-, -C(R3)(aryl)-, -C(O)-, -S-, -0-, -S(O)-, -S(0)2-, a divalent heterocycle and -[C(R3)(R4)]x-arylene-[C(R5)(R6)]y-, or the two benzyl rings of the benzoxazine moieties may be fused;  and R1 and R2 are independently selected from alkyl, cycloalkyl, and aryl, wherein the cycloalkyl and aryl groups are optionally substituted by a substituent selected from: Ci.8 alkyl, halogen and amine groups, and where substituted, one or more substituent groups may be present on each cycloalkyl and aryl group;   R3, R4, R5 and R6 are independently selected from H, Ci-8 alkyl, and halogenated alkyl;  and x and y are independently 0 or 1. 10. The curable resin composition according to any one of claims 2 to 9, wherein the phenol compound (C) is thiodiphenol (TDP). 11. A composite material comprising reinforcement fibers impregnated or infused with the curable composition according to any one of claims 1 to 10. 12. The composite material of claim 11, wherein the reinforcement fibers are selected from carbon fibers, glass fibers, and aramid fibers. 13. A prepreg comprising reinforcement fibers impregnated or infused with the curable composition according to any one of claims 1 to 10, wherein reinforcement fibers are in the form of unidirectional fibers or a fabric. 14. A cured composite part produced from a method comprising: (i) impregnating or infusing reinforcement fibers with the curable composition according to any one of claims 1 to 10;  and (ii) curing the resin-impregnated or resin-infused fibers.
