Wahi a ka hui, ʻoki ke kaʻina hana hou i nā manawa hana mai 3 mau hola a ʻelua mau minuke

Wahi a ka mea hana kaʻa Iapana, ua hana ʻo ia i kahi ala hou e wikiwiki ai i ka hoʻomohala ʻana i nā ʻāpana kaʻa i hana ʻia mai ka carbon fiber reinforced plastics (CFRP) a hiki i ka 80%, e hiki ai ke hana nui i nā mea ikaika a māmā no nā kaʻa hou aʻe.

ʻOiai ua ʻike lōʻihi ʻia nā pōmaikaʻi o ka carbon fiber, hiki ke piʻi aʻe nā kumukūʻai hana ma mua o 10 mau manawa ma mua o nā mea kuʻuna, a ʻo ka paʻakikī i ka hana ʻana i nā ʻāpana CFRP ua hoʻopilikia i ka hana nui o nā ʻāpana kaʻa i hana ʻia mai ka mea.

Ua ʻōlelo ʻo Nissan ua loaʻa iā ia kahi ala hou i ke ʻano hana hana i ʻike ʻia ʻo ka hoʻoheheʻe ʻana i ka resin compression. ʻO ke kaʻina hana e kū nei, ʻo ia ka hana ʻana i ka pulupulu kalapona i ke ʻano kūpono a hoʻonohonoho ʻia i loko o kahi die me kahi hakahaka liʻiliʻi ma waena o ka make luna a me nā fiber carbon. Hoʻokomo ʻia ʻo Resin i loko o ka fiber a waiho ʻia e paʻakikī.

Ua hoʻomohala ka poʻe ʻenekinia o Nissan i nā ʻenehana e hoʻohālikelike pono i ka permeability o ka resin i loko o ke kalapona kalapona ʻoiai e nānā ana i ke ʻano o ka kahe resin i loko o kahi die me ka hoʻohana ʻana i kahi mea ʻike wela in-die a me kahi make aniani. ʻO ka hopena o ka simulation kūleʻa he ʻāpana kiʻekiʻe me ka manawa hoʻomohala pōkole.

Ua ʻōlelo ʻo Hope Pelekikena Hideyuki Sakamoto ma ka hōʻike ola ma YouTube e hoʻomaka ana nā ʻāpana CFRP e hoʻohana ʻia i nā kaʻa hāmeʻa i hana nui ʻia i loko o ʻehā a ʻelima mau makahiki, mahalo i kahi kaʻina hana hou no ka resin i ninini ʻia. ʻO ke kumukūʻai e loaʻa mai ka pōkole o ka manawa hana mai kahi o ʻekolu a ʻehā mau hola i ʻelua mau minuke wale nō, wahi a Sakamoto.
