3. Taolo ea ts'ebetso
(1) Mohlala: Pele o etsa mohlala, sebelisa sampuli e tloaelehileng ea Φ50 × 50mm ho leka matla a khatello ea lehlabathe la resin ≥ 3.5MPa, 'me u tiise tšepe e batang le semathi ho etsa bonnete ba hore hlobo ea lehlabathe e na le matla a lekaneng a ho felisa graphite e hlahisoang ha tšepe e qhibilihisitsoeng e tiisa ho atolosoa ha lik'hemik'hale, le ho thibela nako e telele ho etsa hore karolo e qhibilihisitsoeng e se ke ea ama lehlabathe le lengata.
Ho etsa Core: Mokotla oa lehlabathe o arotsoe ka likarolo tse 8 tse lekanang ka likhopo tse 8 tse matlafatsang, tse hokahaneng ka lehare le bohareng. Ha ho na likarolo tse ling tsa ts'ehetso le tsa ho qeta ntle le hlooho ea mantlha e bohareng. Haeba mokokotlo oa lehlabathe o ke ke oa lokisoa le Mochini, phepelo ea mantlha ea lehlabathe le masoba a moea a tla hlaha kamora ho tšela. Hobane sebaka se akaretsang sa mokokotlo oa lehlabathe se seholo, se arotsoe likarolo tse robeli. E tlameha ho ba le matla a lekaneng le ho tiea ho etsa bonnete ba hore mokokotlo oa lehlabathe o ke ke oa senyeha ka mor'a ho lokolloa ha hlobo, 'me o ke ke oa senyeha ka mor'a ho tšela. Deformation e etsahala, e le ho etsa bonnete ba hore botenya ba lebota bo lekanang ba ho lahla. Ka lebaka lena, ka ho khetheha re ile ra etsa lesapo le khethehileng la mantlha, 'me ra le tlama holim'a lesapo la mantlha ka thapo ea moea ho hula khase e tsoang hloohong ho netefatsa ho kopana ha hlobo ea lehlabathe ha ho etsoa mantlha. Joalokaha ho bontšitsoe setšoantšong sa 4.
