NON-DESTRUCTIVE INSPECTION APPARATUS AND METHOD FOR TOUGHENED COMPOSITE MATERIALS
First Claim
1. A non-destructive composite material inspection apparatus, a surface layer of composite material including a plurality of fibers having a fiber direction and a plurality of toughened particles distributed on the surface layer, comprising:
- a first light module generating a first light ray projecting to a inspection area of the composite material surface, wherein the first light ray is polarized in a polarization orientation; and
a stereoscopic microcamera module capturing the reflection light from the inspection area and outputting an image;
wherein when the polarization orientation and the fiber direction are parallel, the image is a bright field image for analyzing the fiber direction and toughened particle distribution whereas when the polarization orientation and the fiber direction are orthogonal, the image is a dark field image for analyzing the toughened particle distribution and predicting the toughness of the composite material.

Abstract
A non-destructive composite material inspection apparatus and method thereof inspect the fiber direction and fracture toughness. The apparatus includes a light module and a stereoscopic microcamera module. The light module generates a polarized light that has a polarization orientation projecting to an inspection area on the surface layer of the composite material. The stereoscopic microcamera module captures the reflection light from the inspection area and outputs an image. When the polarization orientation and the fiber direction are parallel, the image is a bright field image. When the polarization orientation and the fiber direction are orthogonal, the image is a dark field image. The bright and dark field images show the fiber direction and toughened particle distribution and the toughness of the composite material is then predicted.
