Question

Need help with the learning objectives for this chapter! The book is Materials Science and Engineering An Introduction,9th Edition by William D., Jr. Callister and David G. Rethwisch .

Learning Objectives After studying this chapter, you should be able to do the following: 1. Name the four main divisions of composite 5. Compute longitudinal strengths for discontinu- ous and aligned fibrous composite materials materials and cite the distinguishing feature of each. 6. Note the three common fiber reinforcements 2. Cite the difference in strengthening mechanism used in polymer-matrix composites and, for each, cite both desirable characteristics and limitations. for large-particle and dispersion-strengthened article-reinforced composites. 3. Distinguish the three different types of fiber- reinforced composites on the basis of fiber length and orientation; comment on the distinctive mechanical characteristics for each type 7. Cite the desirable features of metal-matrix 8. Note the primary reason for the creation of 9. Name and briefly describe the two subclassifica- composites ceramic-matrix composites tions of structural composites. 4. Calculate longitudinal modulus and longitudinal strength for an aligned and continuous fiber- reinforced composite

Answer 1

Learning objectives simply specifies that what we are going to study in this particular unit / chapter. It specifies our main objective to learn this chapter.

According to these all learning objectives, we are going to learn following things in this chapter:-

1. After studying this chapter we get an idea about main divisions of composite material and also get distinguish features of each other. they are-

(A) particle reinforced

(B) fiber reinforced

(C) structural

(D) nanocomposites

2. We can see the difference between strengthening mechanism for Large-particle composites (metals, poly-
mers, and ceramics) And dispersion strengthened particle reinforced composites.

3. Types of fiber reinforced composites on the basis of fiber length and orientation:-

(A) continuous aligned

(B) discontinuous aligned

(C) discontinuous randomly oriented

And we also get the infromation about distinctive mechanical characteristics for each type.

4. We can get longitudinal modulus and longitudinal strength for an aligned and continuous fiber inforced composites.

5. After studying this chapter we can also compute strengths for discontinuous and aligned fiber composites.

And so on.

Thus after studying this chapter we get the knowledge about all these learning objective.

So simply these learning objectives give us complete summary about this chapter, what we are going to learn in it etc.
