摘要： An improved flame retardant molding composition of polypropylene terephthalate or polybutylene terephthalate is provided. The composition includes in intimate admixture an oxide of antimony and a specific brominated aromatic polyphosphate copolymer which has been found to be highly compatible with the other components. In a preferred embodiment the molding composition additionally includes a reinforcing agent (e.g. a glass fiber reinforcing agent). Unlike the flame ratardant molding compositions of the prior art, the components of the same tend to be non-exuding during utilization of a resulting three-dimensional shaped article at elevated temperatures (e.g. after 66 hours at 175*C.) and thereby render the same suitable for attractive utilization in an even wider range of applications.

摘要： An improved electrolytic process is provided for modifying the surface characteristics of an electrically conductive high modulus graphitic carbonaceous fibrous material (i.e., exhibiting a mean single filament Young''s modulus of at least about 60 million psi) and to thereby facilitate enhanced adhesion between the fibrous material and a resinous matrix material. The electrolytic process is carried out upon immersion of the fibrous material in an aqueous electrolytic solution of sodium hypochlorite (as defined) provided at a moderate temperature for a relatively brief residence time (i.e., about 2 to 10 minutes) while subjected to a relatively low current density (i.e., about 2.5 to 12 milliamps per square centimeter of surface area of fibrous material), and thereafter washing the same. Composite articles of enhanced interlaminar shear strength may be formed by incorporating the fibers modified in accordance with the present process in a resinous matrix material.

摘要： The efficient production of pervious low density carbon fiber reinforced composite articles is made possible through the use of the present invention. A fibrous open weave tape (as described) which is capable of undergoing conversion to a carbonaceous fibrous material is continuously passed in the direction of its length through a series of heating zones to form a fibrous carbon tape (preferably of graphitic carbon) wherein an open weave construction is maintained. A plurality of layers of the resulting fibrous open weave carbon tape may be impregnated with a thermosetting resinous material, and a plurality of previously superimposed layers of the impregnated tape subsequently cured to form a pervious composite article. The composite articles of the present invention exhibit a high specific modulus and strength, and are extremely lightweight. The lightweight composite articles may be utilized as structural elements, and are particularly suited for use as a facing sheet of an acoustic sandwich liner which serves as a noise suppression function in jet engines.

摘要： Carboxylic acids are converted to the corresponding hydroxymethylsubstituted compounds by preparing an aqueous solution of their alkali metal salts buffered to a pH between about 6.0 and 7.0 and then reacting the buffered salt solution with hydrogen in the presence of a hydrogenolysis catalyst such as active metallic cobalt. In a particularly useful embodiment the potassium salts of carboxylic acids, dicarboxylic acids, and hydroxycarboxylic acids having at least about four carbon atoms are hydrogenolyzed in a reactor within which the desired buffering is accomplished with potassium bicarbonate in the presence of a finite concentration of free carbon dioxide. After the reaction step the liquid product is degassed at a temperature high enough to decompose potassium bicarbonate to potassium carbonate; the reaction product separates into two phases because of the salting-out action of the resulting potassium carbonate, and the organic products can be recovered by decantation while the aqueous phase, containing reuseable potassium carbonate, is recycled to the acid-neutralization step which precedes the hydrogenolysis.
