Mounting of the specimen is often desirable or necessary for handling and metallographic polishing after the specimen is cut into an appropriate size. This article illustrates the different mechanical clamps used in mounting small specimens. It provides useful information on compression molded mounts, which are molded with thermoplastic and thermosetting resins. The article reviews several resins and their key factors, which help in the selection of the most appropriate mounting method and resin. It also discusses the characteristics of plastic mounting materials. The article provides information on the molds and resins used for castable mounts, vacuum treatment of mounts, special mount arrangements, and mount marking and storage.

This article discusses the coating systems categorized by the generic type of binder or resin and grouped according to the curing or hardening mechanism inherent within that generic type. It focuses on the properties, advantages, and limitations of various autooxidative cross-linked resins, thermoplastic resins, and cross-linked thermosetting resins. The autooxidative cross-linked resins include alkyd resins and epoxy esters. The article examines the two types of coatings based on thermoplastic resins: those deposited by evaporation of a solvent, commonly called lacquers, and those deposited by evaporation of water, a class of coatings called water-borne coatings. The coatings that chemically cross link by copolymerization, including epoxies, unsaturated polyesters, urethanes, high-temperature curing silicones, and phenolic linings, are also described.

This article describes the most significant tests to characterize the properties of constituent materials. It discusses the chemical, physical, and mechanical tests for determining the properties of reinforcement fibers and fabrics. The article provides information on some of the basic materials used for thermoset and thermoplastic resin matrices. It reviews the identification of the individual characteristics of thermoset and thermoplastic resin along with the test methods normally used for their determination. The article contains a table that lists properties and tests for uncured and cured thermoset-matrix resins and prepregs.

This article illustrates typical fractographic features for a number of different composite materials. It describes the differences in fracture characteristics due to different loading, material processing, and environmental conditions. The article presents fractographic data obtained from epoxy matrix materials. Minimal fractographic data from other brittle thermoset resin systems are also presented. The article discusses the interlaminar fracture of composites with ductile thermoplastic matrices. It also provides information on the translaminar fracture features of the composite materials.
