This first very basic model of silk was introduced by Termonia in 1994 who suggested crystallites embedded in an amorphous matrix interlinked with hydrogen bonds.
2.
A two-phase composite structure with amorphous matrix and a ductile dendritic crystalline-phase reinforcement, or a metal matrix composite reinforced with fibers of other material can reduce or eliminate this disadvantage.
3.
On a secondary structure level, the short side chained alanine is mainly found in the crystalline domains ( beta sheets ) of the nanofibril, glycine is mostly found in the so-called amorphous matrix consisting of helical and beta turn structures.
