A device for measuring the mechanical properties of micro- and nanoscale fibers

摘要

A device for measuring the mechanical properties of micro- and nanoscale fibers is characterized in that it comprises a housing (1), a force sensor module (12), a sample (13), an expansion module (16), a sample table and a control module. The force sensor module (12) and the expansion module (16) are each mounted on the bottom plate (6), and the force sensor module (12) is provided with a force sensor module chuck (25). The expansion module (16) is provided with a tensile modulus chuck (26). Between the force sensor module chuck (25) and the expansion module chuck (26), a sample table is arranged. The sample table comprises a cross member (19), a protruding end (20) of the sample table, a solid fiber plane (21), a column (22), a fixing seat (23) of the sample table and a sample table plate (24). At both ends of the solid fiber plane (21) columns (22) is arranged. Between the columns (22) has a cross member (19) is arranged. The side wall of the column (22) remote from the fixed fiber plane (21) is connected to one end of the sample table top (24). The other end of the sample table top 24 is connected to the fixation seat 23 of the sample table. The two parallel to the fixing seat (23) of the sample table ends of the column (22) are each provided with the protruding end (20) of the sample table. The fixation seat (23) of the sample table is respectively clamped and connected to the force sensor module chuck (25) and the expansion module chuck (26). The sample (13) is arranged on a fixed boundary plane (21). On the bottom plate (6) a support plate (15) is mounted. The support plate (15) is in each case equipped with a melter module (9), a cold module (10), a temperature sensor (11), a lighting module (14), a heating module (17) and a chamber temperature controlled agitator impeller (18). The melter module (9) comprises a melter head (27) and a melter transition bar (28). One end of the melter transfer bar (28) is connected to the melter head (27). The melter head (27) is located at the back of the sample table.
