North Carolina State University Yin Jie Group AFM: Three-dimensional Paper-cut Programmable Structured Materials

Junction structure of the material feed ( A R & lt C H I T E C T E D m A T E R & lt I A L S ) and the name of machine mechanical ultra material feed ( m E C H A n- I C A L m E T A m a t e r i a l s ) , GuName Si Yi is means over the sheet material of the present body composition physical properties substance of a class of self- natural boundaries do not exist in the man -made material feed
.

It advantage with the new Ying the material feed several any shape shape and junction structure design terms to and its periphery of exemplary junction structure of have sequences rows columns toReal now a few ultra often the material physical properties substance , than as a negative poise pine ratio ( transverse direction tensile elongation guide actuator longitudinally to the swelling expansion ) , the negative thermal expansion expansion ( thermal contraction cold expansion ) , the negative pressure reduction ( static water pressure at not shrink anti bulging ) and the like

The most recent North card Luo Levin Carolina state legislature large study Yin Jie research study small group ( Bo Shi born Li Yan Bin , Bo Shi Zhang autumn Ting , Bo Shi raw Hung Yao Ye ) will be two -dimensional cut paper design meter management concept Tinto exhibition to three -dimensional space between junction structure , and to this wasGroup basis set count out the tool has a super- stage variant form mode type to and wood material properties can be programmed path can force the super- material feed
.

Is not the same in the transmission system thin plate cut sheet in the cut marks FIG pattern , the small groups from a thick plate out of hair ( FIG .

1 A ) , pass through by KAM two -dimensional cut paper processing concept introduced into not the same layer level of the cutting plane , set the count out of a Species may be in real now multipleSpecies space between variant -shaped molded state of the three -dimensional cut paper single element ( FIG .

8 Species not different variant form shaped state

The place in not different variant -shaped form states at the junction structure as is the base of this single element , the small group put out a pass through the fitted jacket groups together not the same but variable shape coordination tone of the single element to construct Jian new the junction structure of sheet material is disposed gauge side case
.

Ratio as inHigh degree direction to stack the stack may be in a form into a dimensional column -shaped member material ( FIG.

1 D and 2 D super- material feed to and can be programmed process variable shape Laid property , ( C - D ) .
3 D super- material feed to and which can be programmed process variable shape Laid properties

This research study real current of the transmission conventional flat plane cut paper to the three -dimensional space between the cut paper square method is a th fly jump , card out of the three -dimensional space between the cut paper having has more big in design terms to and shaped shape variations of empty room , put out the advantage with can change shapeShaped three -dimensional cut sheet single element of the space between the rows of columns and insert fitted to the structure built junction structure of the material feed of the new thinking way
.

Research studies are of be this research study can be in machine mechanical absorbing energy , acoustic learn band gap adjusting section , may be adjusted section just of the machine is human , to andConstruction building materials material to and design terms , etc.
of into a step of be used
