ʻO ka hoʻemi ʻana i ke kaumaha he mea koʻikoʻi ia i ka hoʻolālā ʻana a me ka hana ʻana o nā mokulele, hiki ke hāʻawi i nā mokulele koa me ka ʻoi aku ka ikaika o ka lele ʻana a hoʻomaikaʻi i ka hoʻokele waiwai o nā mokulele mokulele. Akā inā lahilahi ka mānoanoa o nā ʻāpana i hoʻohālikelike ʻia ma ka mokulele, e kū ana ia i nā pilikia o ka lawa ʻole o ka ikaika a me ka ʻoʻoleʻa. Ke hoʻohālikelike ʻia me ka hoʻohui ʻana i nā papa kākoʻo, hiki ke hoʻomaikaʻi maikaʻi i ka hiki ʻana o ka ukana me ka hoʻonui ʻole ʻana i ke kaumaha.

Hoʻopiha ʻia kahi ʻāpana o ka lāʻau māmā a i ʻole ka ʻili i hoʻopiha ʻia ma waena o ka ʻili o loko a me waho o ka ʻili i hana ʻia me ke aniani fiber reinforced epoxy resin (glass fiber reinforced plastic). ʻO ka lāʻau māmā kekahi o nā mea hana sandwich mua loa i hoʻohana ʻia i nā mokulele, e like me ka mokulele lāʻau kaulana i ka wā o ke Kaua Honua II - ʻo ka British Mosquito Bomber, i hana ʻia me ka plywood me ʻelua papa o ka lāʻau birch sandwiched ma waena o kahi papa lāʻau māmā.

I ka ʻoihana mokulele hou, ʻo nā mea kumu i hoʻohana ʻia me ka honeycomb structure a me nā plastic foam. Hiki i ka honeycomb nawaliwali ke pale aku i ka haki ʻana o nā kaʻa koʻikoʻi no ka mea ʻo ka honeycomb paʻa e like me ka hoʻolālā grid ke keʻakeʻa nei i ka deformation buckling, ʻo ia ka mea e like me ka manaʻo i loaʻa i nā pahu pahu corrugated ka ikaika compressive ikaika.

ʻO ka alumini ka metala maʻamau i hoʻohana ʻia ma nā mokulele, no laila he mea maʻamau ka hoʻohana ʻana i kahi ʻano me nā panela alumini alumini a me nā panela sanwika honeycomb aluminika.
