Processing composite materials with lasers

Advanced Concepts of using diode lasers in materials processing

In the last few years impressive advances in the development of high-power diode lasers (HPDL ́s) and their production technology have been achieved /1/. Output powers in the range up to 120 W out of one 10 mm diode laser bar have been reported /2,8/ as well as rapidly declining prices. In the past most activities concerning application of HPDL ́s have been focused on the pumping of solid-state l...

Composite Materials with Enhanced Conductivities

The authors have analyzed the isotropic thermal/electrical conductivities of two types of specially structured composite materials. Closed-form results have been obtained for predicting the conductivities of the composites, and the accuracy has been verified by FE simulations. The obtained results in this paper are compared to the relevant theoretical predictions and experimental measurements. ...

Fibrous Ceramic-ceramic Composite Materials Processing and Properties

Friction Stir Processing of Particle Reinforced Composite Materials

The objective of this article is to provide a review of friction stir processing (FSP) technology and its application for microstructure modification of particle reinforced composite materials. The main focus of FSP was on aluminum based alloys and composites. Recently, many researchers have investigated this technology for treating other alloys and materials including stainless steels, magnesi...

Nanomaterials: Processing and Characterization with Lasers

In conjunctionwith the increasing availability of cost-efficient laser units during the recent years, laser-based micromachining techniques have been developed as an indispensable industrial instrument of ‘‘tool-free’’ high-precision manufacturing techniques for the production of miniaturized devices made of nearly every type of materials. Laser cutting and drilling, as well as surface etching,...
