ʻO ka mea hana kiʻiʻoniʻoni ka ʻāpana nui o ka mea hoʻokomo fiber aniani, ma ke ʻano maʻamau he 2% a 15% o ka hapa nui o ke ʻano infiltrant, ʻo kāna kuleana ke hoʻopaʻa i ka fiber aniani i loko o nā puʻupuʻu, i ka hana ʻana o ka pale ʻana o nā fibers, i loaʻa i nā puʻupuʻu fiber kahi kekelē maikaʻi o ka paʻakikī, ka hoʻohuihui ʻana, e hoʻokō i nā koi hana ma hope i nā huahana fiber aniani. ʻO nā mea hana kiʻiʻoniʻoni i hoʻohana pinepine ʻia i nā ʻano infiltrant fiber aniani he mau polymers, me nā resins epoxy, polyurethane, polyester, phenolic resins, nā dispersions polypropylene i hoʻololi ʻia, a i ʻole nā ​​emulsions. ʻO ka hana o nā mea hana kiʻiʻoniʻoni e hilinaʻi nui ʻia i ka ʻano molekala a me ke kaumaha molekala o ka polymer. No ka mea hana kiʻiʻoniʻoni like, ʻo ka paʻakikī oolonā anianihiki ke hoʻoponopono ʻia e ke kaumaha molekala o ka mea hana kiʻiʻoniʻoni, a ʻo kahi mea hana kiʻiʻoniʻoni me ke kaumaha molekala kiʻekiʻe e loaʻa i kahi ʻoi aku ka paʻakikī o ke aniani fiber, kahi kūpono no ka mālama ʻana i ka ʻili ohoʻoikaika i nā huahana fiber aniani i ʻoki ʻia thermoplastic, ʻoiai he mea hana kiʻiʻoniʻoni me ke kaumaha molekala haʻahaʻa e kūpono no ka hana ʻana o nā olonā i hoʻohana ʻia i ka wili ʻana a me ka huki ʻana i ka hoʻoheheʻe ʻana. Loaʻa i nā polymers resin epoxy nā hui aliphatic hydroxyl, ether, a me epoxy, a he ikaika ka huki kemika ma waena o nā hui polar i nā mea hana kiʻiʻoniʻoni epoxy, no laila he maikaʻi ko lākou hoʻopili ʻana a me ka hopena bundling ma nā fiber aniani;

Eia kekahi, hiki i ka hui epoxy i loko o ka mea hana kiʻiʻoniʻoni epoxy ke hana me ka hui hydroxyl terminal, ka hui carboxyl terminal, ka hui amino terminal, a me nā hui hana ʻē aʻe i nā plastics ʻenekinia e like me PBT, PET, PA, PC, a me nā mea ʻē aʻe, e hoʻomaikaʻi i ka ikaika hoʻopaʻa interfacial ma waena o ke kaula aniani a me ka resin. Loaʻa i nā mea hana kiʻiʻoniʻoni polyester nā hui ester he nui, nā pilina kemika unsaturated, a me nā hui hydrophilic i loko o ke kaulahao nui, a pili kā lākou hana i ke ʻano o ka waikawa a me ka waiʻona i hoʻohana ʻia i ka synthesis o polyester a me ka ratio. Ke resin polyester unsaturated ka resin kumu, hiki i nā pilina pālua unsaturated i loko o ka mea hana kiʻiʻoniʻoni polyester ke polymerize a cross-link me nā pilina pālua i loko o ka resin kumu e hana i kahi pilina kemika ikaika a i ʻole ka entanglement kino, kahi e hoʻomaikaʻi ai i ka ikaika hoʻopaʻa interfacial. ʻO nā mea hana kiʻiʻoniʻoni polyester he mau waiwai wetting a me ke komo ʻana maikaʻi loa a no laila hoʻohana ʻia e like me nā mea wetting i ka pultrusion, winding, spraying, chevron, a me nā huahana ʻē aʻe. Loaʻa i ke kaulahao molekala ʻoniʻoni polyurethane kahi ʻano carbamate hou, ʻo ke ola ʻana o kēia mau hui polar e hoʻolilo i ka polyurethane i ke aniani fiber i kahi nakinaki maikaʻi loa, ʻo nā ʻāpana palupalu a paʻakikī o ka hui pū ʻana o ka elasticity kiʻekiʻe a me ke kū'ē ʻana i ka abrasion, i ka manawa like, hiki ke hoʻokomo ʻia ka polyurethane i loko o ka hui isocyanate me ka amino coupling agent a me ka matrix resin i ka hopena kemika, e hoʻolaha i ka pilina interfacial, hoʻomaikaʻi i ka hana onā mea i hui pū ʻianā huahana.
