This work aims at applying the broadband laser-ultrasonic spectroscopy for quantitative
evaluation of combined influence of the reinforcement fraction and the porosity content on …

Fiber-reinforced polymer composite materials have become materials of choice for
manufacturing application due to their high specific stiffness, strength and fatigue life, low …

Ultrasonic testing is one of the most commonly used non-destructive (NDT) methods to
detect porosity in carbon fiber reinforced polymer (CFRP) material. However, the ultrasonic …

The influence of porosity on the mechanical behaviour of composite laminates represents a
complex problem that involves many variables. Therefore, the evaluation of the type and …

Void defects in the matrix and between fibers inevitably occur during fabricating of fiber
reinforced composites. Although the effects of matrix voids or interfiber voids on the …

Carbon fiber reinforced polymer (CFRP) composites are popular materials in the aerospace
and automotive industries because of their low weight, high strength, and corrosion …

Out-of-plane wrinkles in laminated composites reduce the structural integrity. This study
presents an algorithm to characterize wrinkle height and intensity of each lamina within a …

In powder bed fusion additive manufacturing (AM), the fusing process is temperature and
time dependent. However, little work has been done to understand how different processing …

This work aims at applying the method of broadband laser-ultrasonic spectroscopy for
quantitative evaluation of the effect of isolated dispersed voids and additional extended …

A composite material is a combination of two or more materials with very different
mechanical, thermal and electrical properties. The various forms of composite materials, due …
