Question
In a continuos and aligned fiber composite submitted to a longitudinal loading, failure is NOT catastrophic because:
options:
all fibers fails at the same time but the matrix resist to the applied stess staying intact
the matrix fails but the fibers resist to the applied stress without deforming
not all fibers fracture at the same time and the matrix respond to the applied stress with plastic deformation
all fibers fails at the same time but the matrix resist to the applied stess staying intact
the matrix fails but the fibers resist to the applied stress without deforming
not all fibers fracture at the same time and the matrix respond to the applied stress with plastic deformation
Explanation / Answer
In a continuos and aligned fiber composite submitted to a longitudinal loading, failure is NOT catastrophic because: not all fibers fracture at the same time and the matrix respond to the applied stress with plastic deformation.
Other reasons are not correct because 1) all fibres do not fail at the same time and 2) the matrix do not fail.
