Abstract : This handbook provides information related principally to families of thermoplastics reinforced with strand 'E' glass. The handbook content, while limited to molding materials, advises the reader that other forms of thermoplastic materials-such as foams and elastomers-are also glass reinforced. The wealth of detail and information presented will acquaint US Army Materiel Development and Readiness Command personnel with the range of available materials and their unique mechanical, electrical, and physical properties; fabrication processes, including joining, together with their advantages and disadvantages; and areas of glass-reinforced thermoplastics (GRTP) application. Thus potential uses of GRTP's-with their attendant lower cost and ease of production-are suggested for the design and procurement of Army material. The handbook features the relationships between the GRTP's and their properties-the relationships are displayed both in tabular form and graphically. The influence of composite variables-volume of glass fiber; glass strand solids and bundle size; glass filament diameter, length, and orientation-on properties are similarly displayed. Another unique feature of the handbook is the manner in which the polymers and their associated properties are presented. In one breakout, the GRTP's are displayed as the independent variable; in a second breakout, the properties are displayed as the independent variable.
