Various types of boron filaments were broken in tension in such a way that primary fracture surfaces, and fragments ejected when fracture occurred, were retained. Fracture surfaces observed in the scanning electron microscope could be placed into one of two broad categories. Type I surfaces exhibited primary fracture characteristics such as mirror, mist and hackle zones. Flaws which initiated failure could frequently be resolved. Type II surfaces appeared to be generated by subsequent fracture… Expand
