ʻO ka lāʻau Beech kahi ʻano lāʻau ʻoʻoleʻa me ke ʻano kiʻekiʻe a me ke ʻano paʻakikī. ʻO kona ikaika compressive, ʻo ka lāʻau beech i ʻike ʻole ʻia ka manamana lima a me ka paʻakikī, ʻoi aku ka maikaʻi o ka hana ʻana i nā mea hana kiʻekiʻe-ikaika a me nā mea kūkulu hale. ʻoi aku ka maikaʻi o ke kūʻē ʻana o ka papa hui manamana lima i ʻike ʻole ʻia i ka warping ma mua o nā papa i hoʻomoe pololei ʻia.
He nani loa ka hoʻolālā, me ka ʻāpana hui e hōʻike ana i kahi hiʻohiʻona niho huna. Hūnā a kūlohelohe nā humuhumu, e mālama ana i ke ʻano o ka mauna -ʻano like ʻole a me ke ʻano paheʻe o ka lāʻau beech. ʻO ka hopena hiʻohiʻona holoʻokoʻa kokoke loa i kahi papa paʻa. He maikaʻi nā waiwai kino.
He 15-20% ki'eki'e ka ikaika ku'u 'ana ma mua o ka papa lā'au pa'a. 'Oi aku ka maika'i o ka elastic modulus ma mua o ko nā laminates glued ma'amau.
ʻO ka ʻoluʻolu maʻamau (e mālama mau ʻia i loko o 8-12%)
ʻAʻole hiki ke loaʻa ke ʻano hana chipping
ʻO ka palahalaha o ka ʻili ma hope o ke one hiki ke hiki i ± 0.2mm
Paʻa hale kiʻekiʻe
ʻOi aku ka paʻa o ka hui ʻana o nā niho i hūnā ʻia ma mua o nā papa i hoʻomoe pololei ʻia, ʻoi aku ka ikaika o ka pale ʻana i ka deformation a me ka pohā.
ʻO ka puʻunaue koʻikoʻi o loko o ka lāʻau he ʻano like ʻole, ʻaʻole hiki ke hoʻopaʻa ʻia, a he kūpono ia no ka hana ʻana i nā lako -nui.
Nani a kūlohelohe
ʻO nā humuhumu niho i hūnā ʻia e ʻike ʻole ʻia ka pilina, e like me ka papa piha.
ʻO ka lāʻau beech he huaʻai maʻemaʻe a me ka waihoʻoluʻu mahana, kūpono ia no nā lako hana hou, Nordic a me nā mea ʻē aʻe.
He 15% - 20% kiʻekiʻe ka ikaika piʻo ma mua o ko nā lāʻau paʻa, no laila kūpono ia no nā hale amo.
Loaʻa iā ia ka hana hoʻoponopono maikaʻi, ʻaʻole maʻalahi i ka haki ʻana o ka ʻaoʻao, a he palahalaha ʻili kiʻekiʻe (± 0.2mm).
Nā huahana pale: lāʻau beech ʻike ʻole manamana lima papa, Kina lāʻau beech ʻike ʻole manamana lima lima papa mea hana, mea hoʻolako, hale hana
