1. A composite material comprising:

  • a bonding matrix, anda filler material incorporated in the bonding matrix, the bonding matrix comprising a plurality of bonding elements, each bonding element comprising;

    a core, wherein the core has a first chemical composition that includes one or more chemical elements;

    a first layer at least partially covering a peripheral portion of the core, wherein the first layer has a second chemical composition that is a different chemical composition than the first chemical composition, the second chemical composition including cations corresponding to one of the chemical elements of the first chemical composition; and

    a second layer at least partially covering a peripheral portion of the first layer, wherein the second layer has a third chemical composition that is a different chemical composition than the first and second chemical compositions, the third chemical composition including cations corresponding to one of the chemical elements of the first chemical composition,wherein the bonding matrix is prepared from a porous solid body, the porous solid body comprises a plurality of precursor particles, the precursor particles have a mean particle size of less than 70 μ

    m, and the precursor particles are transformed into the bonding elements,wherein the core comprises at least one synthetic formulation having chemical elements M, Me, and O (oxygen) and/or OH group, M is an alkaline earth metal selected from calcium or magnesium, and Me is selected from a group of metals consisting of silicon, titanium, aluminum, phosphorous, vanadium, tungsten, molybdenum, gallium, manganese, zirconium, germanium, copper, niobium, cobalt, lead, iron, indium, arsenic and tantalum,andwherein the filler material comprises;

    a first plurality of first size particles and a second plurality of second size particles, the second size particles being substantially larger in size than the first sized particles, and wherein the bonding matrix, the first size particles and the second size particles are arranged such that the composite material forms a hierarchic structure.
