Abstract
A composition of a fiber reinforced multi-layered laminate that when compression-molded forms a composite having a Class-A surface that is resin rich. The fiber reinforced multi-layered laminate has an outer layer of a cyclic polyester oligomer containing a latent polymerization catalyst; a glass mat; a core layer of a cyclic polyester oligomer containing a latent polymerization catalyst; a second glass mat, and another outer layer of a cyclic polyester oligomer containing a latent polymerization catalyst. When compression molded, the combination of heat and pressure force the core layer through the permeable glass mats and toward the surface. The latent polymerization catalyst initiates polymerization of the cyclic polyester oligomer forming a Class-A surface that is resin rich. The core layer of a cyclic polyester oligomer thoroughly permeates the reinforcing fiber forming a composite having a middle, with a nearly uniform mixture of reinforced glass fiber and thermoplastic in situ polymerized resin.
