Bafuputsi ba pakile hore lihlomo tsa koloi tse sebelisang lisebelisoa tsa tšepe tse entsoeng ka lekoeba li ka thibela likulo tsa 0.50 le lihlomo tse phunyang lihlomo. Le hoja boima ba eona bo le ka tlaase ho halofo ea boima ba lihlomo tsa tšepe tsa setso, phello ea eona ea tšireletso e tšoana le lihlomo tsa tšepe tsa setso. Ho sibolloa hona ho bolela hore baetsi ba likoloi ba tla khona ho nts'etsapele likoloi tse bobebe tsa sesole ntle le ho tela polokeho, kapa ho ntlafatsa bokhoni ba ts'ireletso ea koloi ntle le ho eketsa boima ba koloi.

Lisebelisoa tsa foam tse entsoeng ka tšepe ke mofuta oa thepa ea foam e entsoeng ka libolo tsa tšepe tse se nang letho. Libolo tsena tsa tšepe li entsoe ka tšepe e sa hloekang kapa titanium ea tšepe 'me li kenngoa ka har'a matrix a tšepe a entsoeng ka tšepe, titanium, aluminium kapa lisebelisoa tse ling tsa tšepe. Phuputsong ena, bafuputsi ba ile ba sebelisa thepa ea tšepe e entsoeng ka tšepe e entsoeng ka tšepe e entsoeng ka tšepe e entsoeng ka tšepe, e bolelang hore sepakapaka le matrix li entsoe ka tšepe.

Phuputsong ena, bafuputsi ba thehile sistimi e thata ea lihlomo e nang le phanele ea ceramic, motsoako oa tšepe oa foam, le poleiti e tšesaane ea aluminium e ka morao. Teko ea lihlomo e sebelisitse likulo tsa 0.50 le lithunya tse phunyeletsang lihlomo. Lebelo la ho qala la lihlomo tsa teko le tloha ho limithara tse 500 motsotsoana ho isa ho limithara tse 885 motsotsoana.
