Preface to the Fourth Edition
It is with great pleasure that I offer this fourth edition of Composite Materials:
Science and Engineering to the readers. The book has been thoroughly updated,
new material been been added in all chapters, plus a new chapter, Repair and
Recycling of Composites, has been added.
The thirdeditionofthis booksaw thelightofthedayin2012.Boeing 787and
Airbus 350 XWB entered into service in 2012 and 2015, respectively. Those two
marked a major shift in the large-scale use of composites. Since then, GE and
Safranhavemadetremendousinroadsintotheuseofceramicmatrixcompositesin
aircraft engines. The cover picture of this edition shows the LEAP engine, which

Preface to the Third Edition
Since the publication of the second edition of this book, there has been a spate of
activity in the field of composites, in the academia as well as in the industry. The
industrialactivity,inparticular,hasbeenledbythelargescaleuseofcompositesby
aerospacecompanies,mainlyBoeingandAirbus.Itwouldnotbefaroffthemarkto
say that the extensive use of carbon fiber/epoxy resin composites in Boeing 787
aircraft anda fairly large use ofcomposites inAirbus’sA380 aircraft represents a
paradigm shift. Boeing 787 has composites in the fuselage, windows, wings, tails,
stabilizers, etc. resulting in 50 percent in composites by weight. Nevertheless, it
shouldbepointedoutthatinreality,theextensiveuseofcompositesinaircraftisa
culminationofseriesofearlierstepsoverthedecadessincemid-1960s.Besides,the
large scale applications in the aerospace industry, there have been impressive
developments in other other fields such as automotive, sporting goods, supercon-
ductivity, etc.
All of this activity has led to a substantial addition of new material in this
edition. Among these are: Carbon/carbon brakes, nanocomposites, biocomposites,
self-healing composites, self-reinforced composites, fiber/metal laminate compos-
ites, composites for civilian aircraft, composites for aircraft jet engine, second
generation high temperature superconducting composites, WC/metal particulate
composites,newsolvedexamples,andnewproblems,etc.Inaddition,Ihaveadded
a new chapter, called non-conventional composites. This chapter deals with some
non-conventional composites: Nanocomposites (polymer, metal, and ceramic
matrix), self healing composites, self reinforced composites, biocomposites, and
laminates made of bidimensional layers.
Onceagain,Ipleadguiltytothechargethatthematerialcontainedinthisedition
is more than can be covered in a normal, semester-long course. The instructor of
course can cut the content to his/her requirements. I have always had the broader
aim of providing a text that is suitable as a source of reference for the practicing
researcher, scientist, and engineer.
