PROBLEM TO BE SOLVED: To provide a foam filling method cable of injecting a liquid formable material by reducing complexity at the time of partitioning a hollow part of a hollow structural member.SOLUTION: A foam filling method flows a liquid formable material into a hollow part 61a of a hollow structural member 61 of a vehicle, thereby to charge a portion of the hollow part 61a with a foamed material formed from the formable material. The foam filling method comprises a partitioning member arranging step, a partition forming step, and a foaming material filling step. At the partitioning member arranging step, a partitioning member 11 having a foaming member 21 for foaming and hardening when heated is provided in the hollow part 61a. At the partition forming step, the foaming member 21 is heated so as to be foamed and set to form a partition wall 41 partitioning the inside of the hollow part 61a. At the foam filling step, a foaming material is poured into the hollow part 61a thereby to fill the foam while restricting the range, in which the foaming material foams while being limited by the partition wall 41.SELECTED DRAWING: Figure 1
【課題】中空構造部材の中空部を区画する際の煩雑さを低減して液状の発泡性材料を注入することのできる発泡体の充填方法を提供する。【解決手段】発泡体の充填方法は、車両の中空構造部材61の中空部61aに液状の発泡性材料を流入し、発泡性材料から形成された発泡体を中空部61aの一部に充填する。発泡体の充填方法は、区画用部材配置工程、区画壁形成工程、及び発泡体充填工程を備える。区画用部材配置工程では、加熱により発泡及び硬化する発泡性部材21を備えた区画用部材11を中空部61aに配置する。区画壁形成工程では、発泡性部材21を加熱することで発泡及び硬化させて中空部61a内を区画する区画壁41を形成する。発泡体充填工程では、中空部61aに発泡性材料を流入し、発泡性材料が発泡する範囲を区画壁41により制限しながら発泡体を充填する。【選択図】図1
