1、Designation:D355217Standard Test Method forTensile Properties of Fiber Reinforced Metal MatrixComposites1This standard is issued under the fixed designation D3552;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revis
2、ion.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope1.1 This test method covers the determination of the
3、 tensileproperties of metal matrix composites reinforced by continuousand discontinuous high-modulus fibers.Nontraditional metalmatrix composites as stated in 1.1.6 also are covered in this testmethod.This test method applies to specimens loaded in auniaxial manner tested in laboratory air at either
4、 room tem-perature or elevated temperatures.The types of metal matrixcomposites covered are:1.1.1 UnidirectionalAny fiber-reinforced composite withall fibers aligned in a single direction.Continuous or discon-tinuous reinforcing fibers,longitudinal and transverse proper-ties.1.1.2 0/90 Balanced Cros
5、splyA laminate composed ofonly 0 and 90 plies.This is not necessarily symmetric,continuous,or discontinuous reinforcing fibers.1.1.3 Angleply LaminateAny balanced laminate consist-ing of 6 theta plies where theta is an acute angle with respectto a reference direction.Continuous reinforcing fibers wi
6、thout0 reinforcing fibers(that is,(645)ns,(630)ns,and so forth).1.1.4 Quasi-Isotropic LaminateAbalanced and symmetriclaminate for which a constitutive property of interest,at a givenpoint,displays isotropic behavior in the plane of the laminate.Continuous reinforcing fibers with 0 reinforcing fibers
