A fan housing assembly of a turbofan engine and method of manufacture includes a fan housing that defines a flowpath radially inward, and a groove structure attached to and located aft of the housing for connection to a stationary portion of an outer shell of a thrust reverser. The groove structure includes a base portion concentrically located about an engine axis, and aft and leading legs spaced axially apart from one another and projecting radially outward from the base portion. The fan housing, the base portion, and the aft and leading legs are made of a one-piece composite material.

The groove structure set forth in claim 6 further comprising: a stop block projecting radially outward from the wear liner at the leading portion. 8. The groove structure set forth in claim 7, wherein the stop block and the leading liner are made of a one-piece metallic material. 9. A fan housing assembly of a turbofan engine comprising: a fan housing located about an engine axis and defining a flowpath radially inward;a groove structure at least in-part located aft of and attached to the fan housing, the groove structure having a base portion concentrically located about the engine axis, an aft leg projecting radially outward from the base portion, and a leading leg projecting radially outward from the base portion and spaced axially from the aft leg, and wherein the fan housing, the base portion the aft leg and the leading leg are made of a composite material; anda flange attached to and projecting radially outward from the fan housing and made of a composite material. 10. The fan housing assembly set forth in claim 9, wherein the groove structure includes a wear liner generally exposed radially outward and attached to at least the leading leg. 11. The fan housing assembly set forth in claim 9, wherein an adhesive bonds the flange to the fan housing. 12. A fan housing assembly of a turbofan engine comprising: a fan housing located about an engine axis and defining a flowpath radially inward; anda groove structure at least in-part located aft of and attached to the fan housing, the groove structure having a base portion concentrically located about the engine axis, an aft leg projecting radially outward from the base portion, and a leading leg projecting radially outward from the base portion and spaced axially from the aft leg, and wherein the fan housing, the base portion, the aft leg and the leading leg are made of a composite material;wherein an adhesive bonds the groove structure to the fan housing. 13. A fan housing assembly of a turbofan engine comprising: a fan housing located about an engine axis and defining a flowpath radially inward; anda groove structure at least in-part located aft of and attached to the fan housing, the groove structure having a base portion concentrically located about the engine axis, an aft leg projecting radially outward from the base portion, and a leading leg projecting radially outward from the base portion and spaced axially from the aft leg, and wherein the fan housing, the base portion, the aft leg and the leading leg are made of a composite material;wherein the groove structure is constructed and arranged to receive a V-blade. 14. A method of manufacturing a fan housing assembly for a turbofan engine comprising the steps of: forming a fan housing of a composite material;forming at least a portion of a groove structure of a composite material; andattaching the fan housing to the portion of the groove structure. 15. The method of manufacturing the fan housing assembly set forth in claim 14, wherein the fan housing is attached to the portion with an adhesive. 16. The method of manufacturing the fan housing assembly set forth in claim 14, wherein the fan housing and the portion are formed in unison and as one continuous composite material. 17. The method of manufacturing the fan housing assembly set forth in claim 14, comprising the further step of: adhering a wear liner to the portion. 18. The method of manufacturing the fan housing assembly set forth in claim 14 comprising the further step of: forming a flange in unison with the fan housing and as one continuous composite material.
