In this study, cross-laminated timber (CLT) was manufactured from rubberwood via hot pressing. The effects of manufacturing parameters, such as resin content and clamping pressure, on the following properties of CLT panels were investigated: density (ρ), water absorption (WA), thickness swelling (TS), bonding strength (BS), compressive strength in the major strength direction of CLT (σ_major), compressive strength in the direction perpendicular to the flat plane of CLT (σ_Flat)), and rolling shear strength (RS). The relationships among the properties of the CLT panel, those the original rubberwood material, and the manufacturing parameters was also explored. The results showed that the resin content and clamping pressure did not significantly affect most of the examined properties of the CLT panels. The ρ, WA, σ_major, σ_Flat, and RS of the panels could be estimated directly from the properties of the original rubberwood, while the TS could be estimated directly from the clamping pressure applied on the panel. However, no such relationship was found for the BS value. Compared with typical softwood-CLT, the rubberwood-CLT exhibited superior mechanical properties. This implies that CLT made of rubberwood can achieve better structural performance than standard CLT can.

在这项研究中，交叉层压木材（CLT）是通过热压由橡胶木制成的。研究了制造参数（如树脂含量和夹紧压力）对CLT面板以下性能的影响：密度（ρ），吸水率（WA），厚度膨胀（TS），粘结强度（BS），抗压强度CLT的主要强度方向（σ_大），在沿垂直于CLT的平面抗压强度（σ_平））和滚动剪切强度（RS）。还探讨了CLT面板，原始橡胶木材料的性能与制造参数之间的关系。结果表明，树脂含量和夹紧压力不会显着影响CLT面板的大多数检查性能。ρ，WA，σ_大，σ_平坦，可以直接从原始橡胶木的特性来估计面板的RS，而可以直接从面板上施加的夹紧压力来估计TS。但是，没有发现BS值具有这种关系。与典型的软木-CLT相比，橡胶木-CLT表现出优异的机械性能。这意味着由橡胶木制成的CLT可以实现比标准CLT更好的结构性能。
