The invention relates to a method for producing a fiber-reinforced plastic (FRP) comparison body for modeling a layer porosity for the non-destructive testing of FRP components, comprising the following steps: i. producing a first part by a. arranging a first FRP layer having a cut-out; b. arranging at least one second FRP layer on the first FRP layer; c. prehardening the assembly of the first FRP layer and the second FRP layer in order to obtain the first part; ii. producing a second part by a. arranging further FRP layers; b. pre-hardening the assembly of further FRP layers in order to obtain the second part; iii. joining the first part to the second part, the cut-out on the first part facing the second part; and iv. hardening the assembly of the first part and the second part, a layer porosity being formed at the cut-out in the first FRP layer.

Method for producing a fiber-reinforced plastic comparison body and testing method

The invention relates to a method for producing a fiber-plastic composite reference body for simulating delamination for the nondestructive testing of FPC components, in particular aircraft components, comprising the following steps: i. producing a first insert by a. arranging a first FPC layer; b. forming a recess in the first FPC layer; c. procuring the first FPC layer, in order to obtain the first insert; ii. producing a second insert by a. arranging a second FPC layer; b. pre-curing the second FPC layer, in order to obtain the second insert; iii. providing at least one first FPC layer and at least one second FPC layer with a first clearance and a second clearance; iv. inserting the first insert and the second insert into the respective clearance of the corresponding FPC layer; v. curing the arrangement, a delamination being simulated at the recess of the first insert.
