Composite semi-finished material, like prepreg for semi-finished structure, has reinforcing fiber structure integrated by interface of two matrix systems, such that reinforcing fiber structure receives connecting forces of matrix systems

摘要

The composite semi-finished material (1) has a reinforcing fiber structure (2) that is integrated by an interface (7) of two matrix systems (4,6), such that the reinforcing fiber structure receives the connecting forces of the matrix systems with loads. The received loads act on the components formed from the composite semi-finished material. The reinforcing fiber structure of the matrix systems is penetrated into the equal portions, so that the interface is located between the matrix systems approximately in a central plane (8) of the reinforcing fiber structure. Independent claims are also included for the following: (1) a method for manufacturing composite semi-finished material; (2) a semi-finished structure with adjacent impregnated surfaces; and (3) a method for manufacturing semi-finished structure.
