摘要	This invention is directed to strongly bonded composite materials and a process for preparing the same, such materials comprising (1) a resinous matrix containing (2) carbon fibers having a Young''s modulus parallel to the fiber axis of at least about 12 X 106 pounds per square inch and having a substantially continuous coating of amorphous carbon applied to the surface of such fibers prior to admixture with the resin matrix.
权利要求	1. A COMPOSITE COMPRISING A POLYESTER RESIN MATRIX CONTAINING A PLURALITY OF FLEXIBLE CARBON FIBERS SAID FIBERS HAVING A YOUNG''S MODULUS PARALLEL TO THE FIBER AXIS OF AT LEAST ABOUT 12 X 10*6 POUNDS PER SQUARE INCH AND THE SURFACE OF SAID FIBER BEING COATED WITH AN ESSENTIALLY CONTINUOUS COATING OF AMORPHOUS CARBON, SAID COATING HAVING A THICKNESS OF FROM ABOUT 20A TO ABOUT 200A AND BEING OBTAINED BY DEPOSITION OF A THERMALLY CARBONIZABLE ORGANIC PRECURSOR ONTO THE CARBON FIBER SAID ORGANIC PRESURSOR BEING THERMALLY CARBONIZED TO AMOROPHOUS FORM AT TEMPERATURES LESS THAN 1,200C. 2. A composite material comprising a vinyl ester resin matrix containing a plurality of flexible carbon fibers said fibers having a Young''s modulus parallel to the fiber axis of at least about 12 X 106 pounds per square inch and the surface of said fiber being coated with an essentially continuous coating of amorphous carbon, said coating having a thickness of from about 20A to about 200A and being obtained by deposition of a thermally carbonizable organic precursor onto the carbon fiber said organic precursor being thermally carbonized to amorphous form at temperatures less than 1,200*C.
