Introduction:
This study aims to investigate the strength characteristics of fiber composites under uniaxial tensile stress.
Methods:
A tensile failure finite element model based on fracture mechanics was built for fiber composites. The principal stress concentration-release-transfer evolution and the crack propagation of the composites under the conditions of equal single fiber width, unequal quantity, and equal total fiber width and unequal quantity were discussed.
Results:
The tensile strength of the composites increased with fiber quantity when the width of each single fiber was equal.
Conclusions:
The tensile strength of the composites increased with fiber quantity when the total width of the composite fiber was equal.

03:35Classifying Matter by Composition
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...
