摘要

This paper outlines sample preparation methodology and providesmechanical property data for commonly used plastic packaging materials.Included are die attach epoxies, mold compounds, liquid encapsulants(glob top material), printed circuit board laminate, and solder mask.Elastic modulus and thermal expansivity were characterized in thetemperature range between -65° C and 260° C. Where possible, datawere measured on samples cut from actual product to account for anymicrostructural effects that are process dependent. If special sampleshad to be fabricated, they were first subjected to the temperatureprofiles expected in actual manufacturing processes before being tested.The main effect of these added thermal exposures was to increase theglass transition temperature

7. Mechanical properties of various concrete after high temperature exposure Mechanical property of various types of concrete after high temperature exposure is investigated. Considering compressive strength requirement for a vertical element in high rise building, concrete specimens with various design strengths of 35, 80, 100, and 150 MPa were tested. Particularly, the influence of incorporated steel fiber on fire resistance is of interest in this study. Experimental results show that the fire resistance depends on the design strength and steel fiber content. Normal strength concrete (NSC) of a design strength of 35 MPa or high performance concrete (HPC) of 80-100 MPa does not spall when exposed to 100-400 °C of temperature. However, an explosive spalling occurs at 300 °C when the HPCs contain 1 vol. of steel fiber. Ultra-high performance concrete (UHPC) of a design strength of 150 MPa and 1.5 vol. of steel fiber also shows dramatic spalling at 300 °C. The experimental results found in this study can contribute to a better understanding of the behaviors of HPC and UHPC under fire and the role of steel fiber on the fire resistance. [O] . 2017
