Minutes of Workshop on Composite Materials Test Methods Held at the Institute for Defense Analyses on February 27, 1985.

This paper presents a review of recent literature related to the static mechanical testing of thermoset-based carbon fiber reinforced composites and introduces a material qualification methodology to generate statistically-based allowable design values for aerospace application. Although most test methods have been found to be effective in determining the specific material properties by incorporating them into the material qualification and quality control provisions, a full validation to clarify the behavior of thermoset-based laminated composite materials is currently lacking, particularly with regard to the characterization of compressive, in-plane, interlaminar shear, and damage tolerance properties. The present study obtains information on the different types of test method that can be employed within the same material properties, and makes an in-depth experimental comparison based on the past literatures. A discussion on the scope of theoretical analysis involves a description of how the proposed test method can be adequate for obtaining more accurate material properties. This discussion is directly applicable to the assessment of material nonlinearity and the geometrical effect of specimens. Finally, the resulting failure modes and the effect of each material property are studied to aid the understanding of the load distribution and behavior of laminated composite materials.

The Matrix

With pulse magnetic field, it is use 2124-K2ZrF6-KBF4 as matrix metal to produce chemical reaction to gain (Al3Zr+ZrB2) p/2124 composite materials in this paper. In this paper, For the sake of researching the microstructure, the morphology, the size and the matrix distribution characteristics of the reinforced grain of prepared composite material , those test methods are used, such as optical microscopy, scanning electron microscope, X-ray diffraction analysis and so on. We will research the magnetic field strength how to influence size and distribution of Al3Zr +ZrB2 particle and the abrasion performance of (Al3Zr+ZrB2)P/2124 composite materials in the room temperature. Wear experiment is proceeding in the CETR UMT 3-V the testing machine and sliding friction is friction way with pin-disc but without lubricant, then analyzes the wear mechanism.
