A Study of the Different Types of Plastics to Ascertain Their Suitability as a Material in the Construction of Projects in Industrial Arts Programs

A Study of the Different Types of Plastics to Ascertain Their Suitability as a Material in the Construction of Projects in Industrial Arts Programs

Date: August 1954
Creator: Fredrickson, Wade O.
Description: This study will not attempt to analyze the various types of plastics presented with respect to the chemical ingredients and chemical processes necessary for their manufacture, but it will deal primarily with the selection and use of the various types of plastics as materials suitable for use in the construction of projects in an industrial arts program.

Fracture Toughness Testing of Plastics under Various Environmental Conditions

Fracture Toughness Testing of Plastics under Various Environmental Conditions

Date: December 1997
Creator: Velpuri, Seshagirirao V.
Description: The primary objective of this study is to test the applicability to plastics of a fracture toughness testing tool developed for metals. The intent is to study pre-test conditioning of several plastic materials and the effect of the depth of the razor notch cut in the chevron notched fracture toughness test specimens. The study includes the careful preparation of samples followed by conditioning in various environments. Samples were subjected to laboratory air for a specific duration or to a controlled temperature-humidity condition as per the ASTM D1870. Some of the samples were subjected to vacuum conditioning under standard test specifications. Testing was conducted using the conventional three-point bend test as per ASTM D5045-95. ASTM E1304, which sets a standard for short rod and bar testing of metals and ceramics provides some basis for conducting chevron notched four-point bend tests to duplicate the toughness tool. Correlation of these results with the ASTM test samples is determined. The four-point bend test involves less specimen machining as well as time to perform the fracture toughness tests. This study of fracture toughness testing has potential for quality control as well as the fracture property determination.

A Study of the Development and Use of Plastics in Industry with Proposals for the Adaptation of Plastics as a Phase of Industrial Arts

A Study of the Development and Use of Plastics in Industry with Proposals for the Adaptation of Plastics as a Phase of Industrial Arts

Date: 1951
Creator: James, A. S., Jr.
Description: The purpose of this study is twofold. First, it is to present evidence of the ever-increasing development and use of plastics by industry. A second purpose after presentation of evidence, is to propose that industrial arts must adapt work with plastics as a phase of its program in order to meet present-day needs of the growing generation.

The Economic Theory of the Chemical Industry

The Economic Theory of the Chemical Industry

Date: 1951
Creator: Lawhon, Edgar C.
Description: The purpose of this thesis is to contrast classical theory with the operations of a controlled industry whose foremost raw material is technical knowledge, and to observe whether these operations can approximate the conditions of orthodox theory.
