Publication number: 20240300191Abstract: A method of embedding a reinforcing fiber into a thermoplastic resin. The method includes providing a cavity defined by first and second members and a seal and enclosing a ply stack. The ply stack includes at least one thermoplastic resin ply including the thermoplastic resin and at least one reinforcing fiber ply including the reinforcing fiber. The method further includes subjecting the cavity to a vacuum to form a vacuum-sealed cavity to impart an impregnation pressure on the ply stack. The method also includes heating the vacuum-sealed cavity to an impregnation temperature above a glass transition temperature of the thermoplastic resin to form a heated thermoplastic resin impregnating into the reinforcing fiber to form a heated composite. The method also includes cooling the heated composite to form a thermoplastic composite.Type: ApplicationFiled: May 17, 2024Publication date: September 12, 2024Inventor: Christopher JOHNSTON, VII

Publication number: 20220389689Abstract: Wear caps protect the wearable surfaces of an adapter for an earth working equipment. These wear caps are subjected to erosion and wear by contact with abrasive material, such as experienced in an excavating operation. The wear caps can be attached to upper and lower legs of the adapter and protect them from wear. Each wear cap is secured to a retention feature on an independent mounting structure. The independent mounting structures are aligned and staggered such that installation of a wear cap onto the rearward independent mounting structure is conducted first. The independent mounting structures on an upper leg may be situated one above the other.Type: ApplicationFiled: August 11, 2022Publication date: December 8, 2022Applicant: ESCO Group LLLCInventors: Abram Hernandez, Yesenia Meraz-Torres, Christopher A.
