Ta. Starzhenetskaya et Nn. Davydova, CHANGE OF THE PHYSICOMECHANICAL PROPERTIES OF FIBROUS POLYMER COMPOSITES EXPOSED TO MOISTURE AND LOW-TEMPERATURES, Mechanics of composite materials, 31(4), 1995, pp. 366-370
We investigated the cyclic effect of water and the simultaneous effect
of water and low temperatures on the properties of fibrous polymer co
mposites. Methods of sorption, thermogravimetry, and mechanical tensil
e, bending, and interfacial shear tests were used. It was established
that for carbon plastic and organite the most aggressive external fact
or is water, and the vulnerable link is the matrix and the reinforcing
fiber. For boron plastic the aggressive factors are water and the joi
nt effect of water and low temperatures; the vulnerable link is the fi
ber-matrix interface.
