樹木は強風や豪雪に見舞われても倒れないように、バネのようにしなやかな構造を持っており、衝撃を吸収できる。木を構成する無数の細胞壁は、衝撃に耐えられるように自ら硬くした細胞壁が骨組みの役割を果たし、強風や豪雪があたっても、クッションのように細胞壁が変形して衝撃を吸収する。また、細胞壁を構成するセルロースという物質は、糸が絡み合ったような繊維状の形をしており、外から力が加わると、この繊維がしなり、衝撃を和らげる。
衝撃を吸収する木材として体育館や病院の床に使われている。
細胞壁の構造派は、2つ以上の異なる素材を一体的に組み合わせた複合材の開発に応用できる。樹木が進化の過程で作り上げた細胞壁の生成プロセスを解明することで、より強度のある新しい複合材の開発に応用できる。
