Transcribed Image Text:

One of the issues that affect composites toughness is the fiber length embedded into the matrix when the matrix has failed. In a tensile test the fiber experienced a stress of 180 MPa at the time the matrix failed. If the tensile strength of the fiber is 450 MPa and the embedded length of the fiber in the matrix is 33 microns, discuss the fiber response after matrix fracture with specific emphasis on the composite toughness. The fiber diameter is 24 microns. One of the issues that affect composites toughness is the fiber length embedded into the matrix when the matrix has failed.
