  • Patent number: 11535568
    Abstract: This invention provides resin formulations which may be used for 3D printing and pyrolyzing to produce a ceramic matrix composite. The resin formulations contain a solid-phase filler, to provide high thermal stability and mechanical strength (e.g., fracture toughness) in the final ceramic material. The invention provides direct, free-form 3D printing of a preceramic polymer loaded with a solid-phase filler, followed by converting the preceramic polymer to a 3D-printed ceramic matrix composite with potentially complex 3D shapes or in the form of large parts. Other variations provide active solid-phase functional additives as solid-phase fillers, to perform or enhance at least one chemical, physical, mechanical, or electrical function within the ceramic structure as it is being formed as well as in the final structure. Solid-phase functional additives actively improve the final ceramic structure through one or more changes actively induced by the additives during pyrolysis or other thermal treatment.

  • Patent number: 11485829
    Abstract: Radiation cured composite materials are greatly improved by enhancing the fiber to matrix bond by prewetting the fibers with an interface resin that has a curing agent mixed in with the interface resin. Furthermore, radiation curing the composite material at or near an expected operating temperature of the composite material improves the mechanical properties of the material by reducing thermally induced strains and stresses caused by thermally curing a material and subsequently cooling the material. Adding an interface resin with a curing agent to the fibers allows relatively thick parts, a must faster curing process, a wide variety of inexpensive and easily workable molding materials, the ability to maintain tight tolerances and reduce or eliminate springback, and a radiation cured material that approaches or exceeds the material characteristics of thermally cured composite materials.

    Abstract: A method of forming a dual cure three-dimensional object by additive manufacturing may be carried out by mixing a first precursor liquid and a second precursor liquid to produce a polymerizable liquid comprising a mixture of (i) a light polymerizable liquid first component, and (ii) a second solidifiable component (e.g., a second reactive component) that is different from the first component (e.g., that does not contain a cationic photoinitiator, or is further solidified by a different physical mechanism, or further reacted, polymerized or chain extended by a different chemical reaction). In the foregoing: (i?) at least one reactant of the second solidifiable component is contained in the first precursor liquid, and (ii?) at least one reactant or catalyst of the second solidifiable component is contained in the second precursor liquid.

  • Patent number: 11440994
    Abstract: A dual-cure method for forming a solid polymeric structure is provided. An end-capped, imide-terminated prepolymer is combined with at least one photopolymerizable olefinic monomer, at least one photoinitiator, and a diamine, to form a curable resin composition, which, in a first step, is irradiated under conditions effective to polymerize the at least one olefinic monomer, thus forming a scaffold composed of the prepolymer and the polyolefin with the diamine trapped therein. The irradiated composition is then thermally treated at a temperature effective to cause a transimidization reaction to occur between the prepolymer and the diamine, thereby releasing the end caps of the prepolymer and providing the solid polymeric structure. A curable resin composition comprising an end-capped, imide-terminated prepolymer, at least one photopolymerizable olefinic monomer, at least one photoinitiator, and a diamine, is also provided, as are related methods of use.

  • Patent number: 11414576
    Abstract: Switchable adhesive compositions are disclosed comprising an adhesive component, which is formed from a material or materials capable of undergoing cross-linking with isocyanale other than by free radical polymerisation and at least one isocyanate having an average of more than one isocyanate functions, unsaturated curable molecules mixed in or partially bound in with the adhesive component, or unsaturated curable moieties fully bound in to the material or materials capable of undergoing cross-linking with isocyanate, and a photoinitiator. The adhesive composition forms a tacky gel-like pressure sensitive adhesive that is capable of moulding to a substrate, and upon activation of the photoinitiator the curable molecules or moieties cross-link to form a dense 3-dimensional network through the adhesive component which causes the composition to become less tacky and to form an elastic film with reduced peel strength.
