Definitions
- the present invention relates to door modules comprising at least one single-layer, continuous fiber-reinforced fiber-matrix semifinished product obtained by impregnating semifinished fiber products with at least one thermoplastic and their use.
- FRP Fiber reinforced plastics
- FRPs Fiber reinforced plastics
- the fibers give the component its mechanical properties. The highest mechanical properties are achieved when the fibers are oriented in a stretched position in the direction of the force flow.
- particularly thin-walled components are produced which are reinforced only at predetermined locations. In the production of such FRP-based components, however, it must be ensured with great effort that the reinforcing elements do not leave their preselected position or slip unintentionally.

The cooling to room temperature within 60 s was carried out at a surface pressure of 7.5 bar. Due to the different viscosities of the thermoplastic Matrizes 1 and 2, there was a non-uniform structure of the fiber-matrix semifinished product.

For this purpose, a cross-section of fiber-matrix semi-finished products (1) and fiber-matrix semi-finished products (2) was examined by means of a computer tomograph Micro CT nanotom S from the manufacturer General Electric. For statistical reasons, three test specimens were examined, each with 5 repeat measurements.

- Table 1 Test parameters in tensile test h As a criterion for the bond strength, the maximum measured force determined in the tensile test was defined. First measurable force drops were caused by initial cracks in the material, peelings, deformations or similar effects before reaching maximum force and appeared to be unsuitable as a bond strength criterion. The maximum measured force was reached in case of failure of the head tension test; It is therefore referred to below as the breaking force. Basically, it should be noted that the maximum force in addition to the bond adhesion and the geometry can always depend on the test method and the test conditions.
- thermoplastic matrix 1 In the case of the fiber matrix semifinished product (1) (according to the invention), in all cases a purely cohesive failure of the thermoplastic matrix 1 occurred directly at the uppermost semifinished fiber layer of the semi-finished fiber product.

A cohesive failure of thermoplastic matrix 1 above the uppermost semi-finished fiber layer was not observed.
- thermoplastic matrix 2 In the non-inventive fiber-matrix semifinished product (2) thus the near-surface layer (surface) of thermoplastic matrix 2 from the substrate consisting of semifinished fiber and thermoplastic matrix 1, demolished, while the invention, single-layer fiber-matrix semifinished product (1) no Such separation was observed within a surface-parallel layer in the thermoplastic matrix 1.
- test results show that the maximum force in the comparisons of the two fiber-matrix semifinished products in the single-layer fiber-matrix semifinished product (1) according to the invention always turned out to be higher than in the case of the fiber-matrix semifinished product (2) with layered structure. Also, the mean value of the individual test results of the measurement series was significantly higher than that of the fiber-matrix semifinished product (2) in the single-layer fiber-matrix semifinished product (1) according to the invention.
- the rib peel strength of the single-layer fiber-matrix semifinished product (1) according to the invention was markedly higher than that of the fiber-matrix semifinished product (2), which is why a monolayer fiber-matrix semifinished product according to the invention, used as a door module, has clear advantages over fiber According to the prior art.
