Problems solved by technology

However, the present method for manufacturing off-axis unidirectional prepreg is time consuming and requires a highly skilled workforce to achieve the required quality levels of rolls of off-axis prepreg material
Additionally, the output rate of off-axis unidirectional prepreg material produced using conventional methods can be less than that required to provide sufficient volume of material to support automated layup

Embodiment Construction

[0050] Referring now to the drawings, in which are shown for purposes of illustrating various embodiments of the present disclosure, figure 1 Shown is a block diagram of an example of a machine 100 for making rolls of off-axis unidirectional thermoplastic prepreg material. The unidirectional thermoplastic prepreg material may comprise a thermoplastic matrix material 162 ( Figure 8 ) of multiple reinforcing fibers 160 ( Figure 8 ). Machine 100 may manufacture lengths of off-axis unidirectional thermoplastic prepreg material by seam welding end-to-end series of unidirectional thermoplastic prepreg pieces 172 . The prepreg 172 may initially be formed from a roll of 0° unidirectional thermoplastic prepreg material with unidirectional fibers 160 ( Figure 9 ) cut, most of the unidirectional fibers 160 can be parallel to the longitudinal direction 188 of the 0° material ( figure 2 ) orientation. Prepreg 172 may be provided from a supplier of a desired size and geometry.

Abstract

The present invention relates to a system and method for making off-axis prepreg materials. An off-axis prepreg material manufacturing machine (100) may include a robot (120) configured to position a prepreg piece (172) adjacent an end of a prepreg layer (180). The machine (100) may additionally include an alignment system (200) configured to sense the position of the prepreg (172) relative to the prepreg layer (180) and A position signal representing the position is generated. The machine (100) may further include a controller (192) configured to receive the position signal and cause the robot (120) to adjust the position of the prepreg (172) , so that the end edge of the prepreg (172) and the end edge (184) of the prepreg layer (180) substantially abut.

Description

technical field [0001] The present disclosure relates generally to composite materials, and more particularly to systems and methods for fabricating off-axis unidirectional fiber-reinforced polymer matrix materials. Background technique [0002] The manufacture of composite parts may involve laminating multiple plies or layers of fiber-reinforced polymer matrix material. Each layer may be formed from unidirectional fibers. Fibers can be pre-impregnated with resin (eg, prepreg) to simplify the manufacturing process. The fibers in each layer of the composite part may be oriented at specific angles relative to the fiber orientation of the other layers as a means of optimizing the strength and stiffness properties of the composite part. Unidirectional prepregs are available in rolls of 0° material where most of the fibers are oriented parallel to the longitudinal direction of the material. 0° rolls are available in different widths for use in automated lay-up equipment. For ...
