The invention discloses a shock-resistant thermoplastic liner for a helmet, which is formed by stacking multiple layers of sheets processed into a head shape. Each layer of sheet is provided with arrayed hemispherical cavities which are open cavities, and the hemispherical cavities of adjacent sheets are nested, butted or engaged with each other. The middle part of the liner contains spheroid-like hollow bodies distributed in an array, which are formed by butting the hemispherical cavities of adjacent two layers of sheets. The manufacturing method of the liner comprises: firstly manufacturing a helmet-like sheet base without hemispherical cavities through injection molding, pressing or blow molding; then forming the arrayed hemispherical cavities on the sheet base through a suction-blow molding process; finally stacking, bonding and punching multiple layers of sheets in a nested, butted or engaged manner to obtain the shock-resistant thermoplastic liner for a helmet. The invention has the advantages of simple structure, comfortable wearing, convenient processing, environment-friendly materials, suitability for personalized customization and the like.
