Manual on Experimental Methods for Mechanical Testing of Composites

Few would argue that there has been tremendous activity surrounding composite materials in the last few decades. Simply put, composite materials are those comprising at least two distinct materials phases: a matrix material in which is embedded a reinforcement material. Clearly by that definition, composite materials have been around for a very long time. Some composite materials occur naturally, such as wood; other man-made materials, such as concrete, have a long history of development and application.

It is, however, modern, high-performance composites that have truly revolutionized recent technology. One can point to their high specific strength and stiffness, of course. But what has been truly revolutionary is that, unlike an earlier time wherein the materials were selected to fit the design after the fact, modern composites now allow for the materials themselves to be designed, simultaneously, along with the rest of the structure or system.

Thus modern composites are perhaps the largest embodiments of what can be truly called engineered materials, and their use is ever growing. The Composites Institute (New York, NY) estimates that composite shipments reached 3.28 billion pounds in 1996, a 3.2 percent increase over 1995, and a 38.2 percent increase since 1991. Evolving technologies are leading this increased usage of composite materials; there is no indication that these trends will subside.

It is from this background that we find the motivation for the second edition of the Manual, offered in the pages that follow. As its name implies, the Manual focuses on experimental methods that improve our understanding of the mechanics of composite materials. Experimental methods play a variety of roles in this effort. As they always have since the earliest of times, experimental methods provide insight into the form and constitution of theoretical models. Experiment then plays an important role in the verification of those very theories. Experiments also provide critical means for material characterization and damage detection. Since many of these experimental methods are evolving, it was felt that a second edition of the Manual was appropriate at this time. Nearly one-half of the Manual is either new or revised.
