復(fu)合(he)球(qiu)(qiu)棒(bang)(bang)(bang)(bang)(bang)的(de)(de)(de)(de)(de)(de)材質為白楊木、楓木與竹片聚(ju)合(he)壓縮而成,也(ye)有人稱(cheng)之為「壓縮棒(bang)(bang)(bang)(bang)(bang)」、「合(he)成棒(bang)(bang)(bang)(bang)(bang)」、甚(shen)至「竹棒(bang)(bang)(bang)(bang)(bang)」。由於復(fu)合(he)球(qiu)(qiu)棒(bang)(bang)(bang)(bang)(bang)融合(he)了木棒(bang)(bang)(bang)(bang)(bang)與鋁(lv)棒(bang)(bang)(bang)(bang)(bang)的(de)(de)(de)(de)(de)(de)優點,彈性較佳而且不(bu)(bu)易斷裂(lie),揮擊(ji)時的(de)(de)(de)(de)(de)(de)力(li)道其(qi)實不(bu)(bu)會輸給鋁(lv)棒(bang)(bang)(bang)(bang)(bang),所以在(zai)(zai)一般(ban)國(guo)(guo)際正式比賽場(chang)合(he),通常(chang)都是(shi)(shi)不(bu)(bu)被(bei)允許使(shi)用(yong)(yong)的(de)(de)(de)(de)(de)(de);不(bu)(bu)過由於國(guo)(guo)際棒(bang)(bang)(bang)(bang)(bang)球(qiu)(qiu)總會積極(ji)推展(zhan)國(guo)(guo)際賽事全面改用(yong)(yong)木棒(bang)(bang)(bang)(bang)(bang)的(de)(de)(de)(de)(de)(de)政策之下,復(fu)合(he)球(qiu)(qiu)棒(bang)(bang)(bang)(bang)(bang)已經被(bei)視為全面改用(yong)(yong)木棒(bang)(bang)(bang)(bang)(bang)前的(de)(de)(de)(de)(de)(de)過渡球(qiu)(qiu)棒(bang)(bang)(bang)(bang)(bang),在(zai)(zai)國(guo)(guo)內(nei)三級棒(bang)(bang)(bang)(bang)(bang)球(qiu)(qiu)比賽中,球(qiu)(qiu)棒(bang)(bang)(bang)(bang)(bang)當(dang)然不(bu)(bu)可(ke)能(neng)是(shi)(shi)純「鋁(lv)」所制成,通常(chang)是(shi)(shi)以合(he)金成份為主。鋁(lv)棒(bang)(bang)(bang)(bang)(bang)的(de)(de)(de)(de)(de)(de)使(shi)用(yong)(yong)已經日漸(jian)式微,在(zai)(zai)重要的(de)(de)(de)(de)(de)(de)國(guo)(guo)際比賽當(dang)中,幾乎(hu)已經看(kan)(kan)不(bu)(bu)到了;在(zai)(zai)國(guo)(guo)內(nei)的(de)(de)(de)(de)(de)(de)三級棒(bang)(bang)(bang)(bang)(bang)球(qiu)(qiu)比賽中,有時仍然看(kan)(kan)得到鋁(lv)棒(bang)(bang)(bang)(bang)(bang)的(de)(de)(de)(de)(de)(de)身(shen)影。
1.若材質(zhi)強度高 - 硬度/韌(ren)性高,傳到球的力道(dao)較(jiao)直接,能量損耗(hao)較(jiao)少,此謂棒子(zi)的彈性系數高;
2.擇材質彈性低 - 較硬的東西,就比較不那么flexible,而(er)且回到(dao)手(shou)掌的震動較大,這可以理解;
3.在此同時 - 棒(bang)子比較(jiao)耐用不易斷。
球 棒木(mu)(mu)質不比手套(tao)皮(pi)革嬌嫩,倒(dao)是(shi)木(mu)(mu)、竹材質都怕濕,保持干(gan)爽的(de)(de)細(xi)節(jie)要(yao)注(zhu)意。新棒會上漆(qi),不只是(shi)印(yin)logo、討個亮麗外(wai)觀,主(zhu)要(yao)能防濕氣,如(ru)同所(suo)有木(mu)(mu)制品一般。球棒打久會磨擦掉漆(qi),此(ci)時更應該注(zhu)意保存時的(de)(de)防濕。
