Problems Encountered with Conventional Fiber-Reinforced Composites
The problems encountered in dealing with composites can be usefully classified as preparational, computational and operational. That is, we first ask how it is made and the effects of process variables, including the resultant chemistry, on the initial properties.* Then, knowing (or presuming) the component properties and attributes, one may try to calculate the properties of any given composite structure made from these and at the same time estimate its ability to withstand some generalized stress field, i.e., some combination of mechanical, thermal or environmental loads for some stated period of time. Finally, we can ask what problems are encountered under use conditions.
