摘要： The present invention relates to a (meth)acrylic composition suitable for (meth)acrylic polymeric compositions and (meth)acrylic polymeric composites, its method of preparation and its use. In particular the present invention relates to a (meth)acrylic composition that is slightly crosslinked once polymerized and that is suitable for (meth)acrylic composites and more particular for rebars. More particularly the present invention relates to a (meth)acrylic composition suitable for rebars, preparing such a (meth)acrylic compositions, composite rebar comprising is and method of preparing such a composite rebar. The present invention also relates also to the use of such a (meth)acrylic composition and use of rebars.

摘要： A method for making a high temperature composite, which is a carbon carbon composite, carbon fiber reinforced ceramic matrix composite, ceramic fiber reinforced ceramic matrix composite, or a carbon silica composite, including: a) providing a precursor part including a resin comprising a poly(aryl ether ketone) (PAEK) and at least one reinforcing material, wherein the resin has a degree of crystallinity of 10% or more; b) pyrolyzing the precursor part to a pyrolyzed part; c) infusing a liquid second resin into the pyrolyzed part to make an infused part; and d) pyrolyzing the infused part to make the carbon carbon composite carbon fiber reinforced ceramic matrix composite, ceramic fiber reinforced ceramic matrix composite, or the carbon silica composite, optionally repeating steps c. through d. Also, a carbon carbon composite, carbon fiber reinforced ceramic matrix composite, ceramic fiber reinforced ceramic matrix composite, or carbon silica composite made by the method.
