Abstract

PROBLEM TO BE SOLVED: To correctly grasp and inspect the entirety of a composite material while forming a composite material by non-destructive and numerical operation as to whether it is in a desired state or not by installing a device for grasping and inspecting the adherence state of a composite material in a laminate apparatus for forming a composite material by adhering a plurality of composite materials. SOLUTION: The lamination apparatus works to composite material 7 by holding material 5 having an adhesive applied and material 6 having no adhesive applied between an adherence roller 1 and a compression roller 2. In this instance, composite material 7 is taken up by a winding part 4 by a device 3 for grasping and inspecting the adherence state of composite material while grasping and inspecting the adherence state thereof. The inspection device 3 operates to give vibration to the composite material by a vibrator in accordance with an output from a signal generator, and measure the shift and acceleration by a sensor, and obtain a transfer function by comparing each output, and thereafter, its adherence state is comparison-determined by a comparison determination means by comparing the transfer function with a base data.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laminating apparatus having a device for bonding a plurality of materials to form a composite material and for grasping and inspecting the state of bonding of the composite materials.

[0002]

2. Description of the Related Art Conventionally, when a composite material is made by laminating a plurality of materials with a laminating apparatus, a grasping test for judging whether or not the composite material is in a desired bonding state is performed by stopping the laminating apparatus. This is performed by measuring the lamination strength of a piece obtained by cutting out a part of the composite material.

[0003] Therefore, in the conventional grasping inspection, a piece obtained by cutting out a part of the composite material to be measured is measured, and thus there are the following three problems. First, it is impossible to determine whether or not the entire composite material is in a desired bonded state. Second, non-destructive inspection cannot be performed. Third, the laminating apparatus must be temporarily stopped, and a grasp inspection cannot be performed in real time.
