摘要： A method for making a carbon carbon, carbon ceramic matrix, or carbon silica composite, comprising melt processing a resin comprising a polyaryletherketone (PAEK) and at least one reinforcing additive to make a precursor part, pyrolyzing the precursor part to make a pyrolyzed part, infusing a liquid second resin into the pyrolyzed part to make an infused part, and pyrolyzing the infused part, wherein the temperature within the chamber increases one or more times at a rate from 1 °C/h to about 20 °C/h during said pyrolyzing, and wherein optionally said pyrolyzing is maintained for a period of time at one or more temperatures. Other methods comprise processing aligned reinforcing additives and a resin comprising a PAEK to make an aligned reinforcing additives PAEK, aligned 1-2 dimensional flake material, or aligned 1-2 dimensional platelet material, to create a fabric, prepreg or tape comprising the aligned reinforcing additives and impregnated PAEK. Other methods comprise impregnating continuous fiber tape or fabric with a resin comprising PAEK and at least one reinforcing additive or co-weaving a continuous fiber or fabric with a PAEK fiber comprising PAEK and at least one reinforcing additive.

摘要： The invention relates to an additive manufacturing process by extrusion for forming a three-dimensional part in an additive manufacturing machine having a build environment, the process comprising: - i) providing a composition comprising at least one poly-aryl-ether-ketone (PAEK) having a melt viscosity from about 200 Pa.s to about 1500 Pa.s, according to ASTM D3835-16, measured at a temperature of 320°C and at a shear rate of 100 s -1 , by capillary rheology using a 1 mm diameter, 15 mm long die; - ii) extruding the composition in the build environment at an extrusion temperature equal to 330°C or less, to form an extruded part section; and, - iii) cooling the extruded part section in the build environment. The invention also relates to a filament and its use in said additive manufacturing process and the corresponding object obtainable from said additive manufacturing process.

摘要： The invention concerns an additive manufacturing process by extrusion for forming a three-dimensional part with an additive manufacturing machine comprising a nozzle, the process comprising: - i) providing a pseudo-amorphous composition having a glass temperature Tg; - ii) softening the composition at a softening temperature above Tg and below 300°C to form a softened composition which is fluid enough to flow and, extruding the softened composition from the nozzle to form an extruded part section; and, - iii) solidifying the extruded part section; wherein the composition is based on a homopolymer or a copolymer of poly-ether-ketone-ketone, consisting of : at least an isophthalic (I) repeating unit, having the formula(I); and, in the case of the copolymer, a terephthalic (T) repeating unit, having the formula (II); wherein the molar proportion of T units relative to the sum of the T and I units ranges from 0% to 45% or from 55% to 65%.
